Foreword

This British Standard is one of a series based upon the recommendations in the report (published in 1969) of the Home Office Gas Cylinders and Containers Committee for materials, design, construction, testing, filling and maintenance of containers intended for the conveyance by road of permanent and liquefiable gases under pressure.It has been prepared under the auspices of the Pressure Vessel Standards Committee at the request of the Home Office in order to satisfy the technical requirements of new legislation currently under consideration for such conveyance.This particular standard deals with filling ratios and developed pressures for liquefiable and permanent gases filled into containers.This British Standard replaces BS 1736 published in 1951 and presents a wider scope in that filling ratios are specified for a greater number of liquefiable gases and it also specifies the developed pressures for permanent gases. BS 1736 is now withdrawn.A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application.

Compliance with a British Standard does not of itself confer immunity from legal obligations.

Summary of pagesThis document comprises a front cover, an inside front cover, pages i to iv, pages 1 to 40, an inside back cover and a back cover.This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover.

1 ScopeThis British Standard specifies the filling ratios and developed pressures to be used when filling, selecting or designing containers of 1 litre water capacity and above for conveyance of liquefiable or permanent gases by road within the United Kingdom.NOTE As guidance only, for overseas markets, corresponding filling ratio and developed pressure data for climatic areas other than the United Kingdom are given in Appendix C.

2 ReferencesThe titles of the British Standards referred to in this standard are listed on the inside back cover.

3 DefinitionsFor the purposes of this British Standard the following definitions apply.

3.1 critical temperature

the temperature above which the substance cannot exist in a liquid state

3.2 liquefiable gas

a gas which is liquefiable by pressure at – 10 °C but which is completely vapourized at 17.5 °C when at not more than 1 013 mbar1)

3.3 high-pressure liquefiable gas

a gas which has a critical temperature from – 10 °C to 70 °C inclusive

3.4 low-pressure liquefiable gas

a gas which has a critical temperature above 70 °Cthose toxic substances which are liquid at 1 013 mbar1) pressure at 0 °C but which boil at or below 30 °C at that pressure shall be treated aslow-pressure liquefiable gases

3.5 permanent gas

a gas which has a critical temperaturebelow – 10 °C

3.6 filling ratio

the ratio of the mass of gas introduced into a container to the mass of water (water capacity) at 15 °C that fills the container fitted as for use, i.e. complete with valve, dip tube, float etc, as necessary

NOTE The water capacity stamped on the container may refer to the minimum designed water capacity of the container without fittings, in which case the net water capacity must be ascertained.Although water capacity is defined as a mass it may be expressed as a volume.

where filling ratios are calculated in accordance with the requirements of Appendix A they shall be maximum values and hence the filling mass charged into a container must take account of the accuracy of the filling procedure

3.7 developed pressure

the pressure developed by the contents of the container at the pressure reference temperature as given in Table 2

3.8 reference temperature for filling ratio

the temperature at which the liquid density is to be evaluated for calculating the filling ratio

3.9 reference temperature for developed pressure

the temperature at which the developed pressure is to be determined

3.10 maximum permissible pressure

the maximum permissible pressure in service is the pressure developed by the contents at the pressure reference temperature taking into account the filling ratio for high pressure liquefiable gases and the intended charging pressure at 15 °C for permanent gases

4 General4.1 Table 1 classifies those gases conveyed in commercial quantities for which data are given in this standard. It also indicates any associated hazard.4.2 The reference temperatures for filling ratio and for developed pressure referred to in this standard vary with the size of container. The relationship between reference temperature and container volume is given in Table 2.4.3 Where filling ratios and developed pressures are not specified for gases or gas mixtures, the procedure to be followed is included as Appendix B to this standard.

4.4 The developed pressure figures quoted in the various tables are assumed to be for pure gases. If impurities are present the effect on the developed pressure must be taken into account, for example, by treating the impure substance as a mixture for the purposes of Appendix A.4.5 The physical data for the majority of the gases in this standard are taken from the Report of the Home Office Gas Cylinders and Containers Committee, published in 1969. Pressure values have been converted from lbf/in2 to bar2) using a factor of 0.068 947 6 and rounded to the same number of significant figures as in the above report.

5.1 High pressure liquefiable gases

5.1.1 The chosen filling ratio shall be such that1) The pressure developed by the contents at the reference temperatures does not exceed the maximum permissible pressure.

2) The pressure developed at 5 °C above the reference temperature does not exceed the maximum permissible pressure by more than 20 %.

5.1.2 Filling ratios and the associated developed pressures at the reference temperatures applying in the United Kingdom for different sizes of containers are given in Table 3. If it is desired to use containers designed for developed pressures other than those given in Table 3, then the procedure in Appendix B shall be followed.Formulae for calculating filling ratios are given in Appendix A. In calculating the filling ratio from the physical data, allowance shall be made for the negative degree of uncertainty in the accuracy of the density data.5.1.3 For impure gases and mixtures of high pressure liquefiable gases with other gases, the permissible filling ratio shall be determined experimentally so as to comply with the requirements of 5.1.1.5.1.4 For guidance only for overseas markets, corresponding filling ratio and developed pressure data for climatic areas other than the United Kingdom are given in Appendix C, Table 19.

5.2 Low pressure liquefiable gases

5.2.1 General. The chosen filling ratio shall be such that in no circumstances shall the liquid portion of the gas occupy more than 97 % of the volume of the container at the filling ratio reference temperature, nor shall the container be liquid full at a temperature 5 °C greater than the filling ratio reference temperature.Formulae for calculating filling ratios are given in Appendix A. In calculating the filling ratio from the physical data, allowance shall be made for the negative degree of uncertainty in the accuracy of the density data.5.2.2 Filling ratios. The filling ratios to be used for the commercially pure gases listed in Table 1 are given in Table 6. Columns giving the vapour pressure developed at the pressure reference temperature associated with the filling ratio reference temperature have also been included.Vapour pressure data for commercial butane and commercial propane as defined in BS 4250 are given in Table 7.5.2.3 Mixtures of low pressure liquefiable gases. Except as allowed under 5.2.4 the density of a mixture of low pressure liquefiable gases shall be determined experimentally at the appropriate filling ratio reference temperature, from which, after allowance for the tolerance on the proportions of the mixture, the filling ratio shall be determined in accordance with 5.2.1. Alternatively the density of the mixture may be calculated using the formula given in Appendix A.

5.2.4 Mixtures of liquefiable petroleum gases. For mixtures of liquefiable petroleum gases Table 8 to Table 15 should be used for obtaining filling ratios appropriate to the reference temperature. The density of the mixture shall be determined experimentally at a convenient temperature and for any given reference temperature the maximum permissible filling ratio is the value at the intersection of the row beginning with the value determined for the density and the column headed by the temperature at which it was determined. See 5.1.1 and Table 2 for the association of reference temperature with size of container.5.2.5 Mixtures of liquefiable petroleum gases consisting wholly of saturated hydrocarbons.Table 8, Table 10, Table 12 and Table 14 give the maximum permissible filling ratios for mixtures of liquefiable petroleum gases consisting wholly of saturated hydrocarbons.5.2.6 Mixtures of liquefiable petroleum gases consisting wholly of unsaturated hydrocarbons or containing more than 2 mol % of C2 hydrocarbons. Table 9, Table 11, Table 13 and Table 15 give the maximum permissible filling ratios for mixtures of liquefiable petroleum gases consisting wholly of unsaturated hydrocarbons, or containing more than 2 mol % of C2 hydrocarbons.

Liquid density data for 43 °C, 47.5 °C and 50 °C are quoted to ensure compliance with the over-rider on filling ratio given in 5.2.1. Except where stated, these data relate to the pure gases. For certain gases the probable impurities are such that it would be necessary to reduce the filling ratio, and cases of doubt should be referred to HM Inspector of Explosives.

7 Developed pressure for permanent gases7.1 Table 16 shows, for the United Kingdom, reference temperature of 60 °C common to all sizes of container for permanent gases, the relationships between the maximum permissible charging pressure at 15 °C for the commonly used permanent gases and their developed pressures at the reference temperature. Linear interpolation is permissible to derive other relationships between the charging pressure at 15 °C and the developed pressure at reference temperature.7.2 The compressibilities of the components of a mixture of permanent gases are not always additive. Therefore, for mixtures the filling pressure at 15 °C shall be obtained experimentally.7.3 For boron trifluoride, the maximum filling pressure shall be 60 % of the maximum permitted developed pressure for which the container is designed or 136.5 bar7) gauge, whichever is the smaller.7.4 For fluorine, no container shall be filled with more than 5 kg of gas and the pressure at 15 °C shall not exceed 27.5 bar gauge. Containers shall be designed for a maximum developed pressure of 200 bar gauge at the reference temperature.

7.5 For coal gas, the relationship between the charging pressure and developed pressure at reference temperature is dependent upon the composition of the gas mixture. The relationships given in Table 16 for methane shall apply to coal gas except where specific approval has been obtained under the terms of Appendix B for a defined coal gas mixture.7.6 As guidance only for overseas markets, corresponding developed pressure data for climatic areas other than the United Kingdom are given in Appendix C, Table 31.

8 Large containers8.1 For large insulated containers reference temperatures lower than those specified in 5, 6 and 7 may be used with the agreement of HM Inspector of Explosives.8.2 In the case of large insulated containers used for the conveyance of high pressure liquefiable gases at sub-normal temperatures, the mass of the gas to be filled into the containers shall be such that the liquid portion shall occupy not more than 98 % of the container volume at the highest temperature likely to be reached in conveyance or at the pressure at which any safety devices fitted operate.

Appendix A Determination of filling ratios and developed pressures

This appendix details the basis on which the filling ratios and developed pressures are determined, and defines the way in which they should be applied in practice.A.1 Low pressure liquefiable gasesA.1.1 Filling ratios for single components (see 4.4). The filling ratio is defined so as to leave a guaranteed free space of 3 % at the appropriate reference temperature. It is normally calculated from the formula

whereÔl is the density of liquid phase of gas at the reference temperature of filling ratioC is the confidence limit on data for liquid density %Ôw is the density of water at 15 °C.

Formula 1 assumes that the whole of the contents are in the liquid phase. If the mass of gas in the vapour phase is allowed for, slightly greater ratios could apply, calculated from the formula

whereÔg is the density of gaseous phase of gas at the reference temperature for developed pressure.

NOTE The adjustment afforded by formula 2 is of value only when density of the gaseous phase exceeds 0.33 g/cm3.

A.1.2 Filling ratio for mixtures except hydrocarbon gases (see Table 8 to Table 15). Where containers are to be filled with a mixture of gases or of gases and liquids, where the liquid densities of the individual components are known, the filling ratio can be calculated as follows.An adjustment shall be made to the percentages of the components in such a manner as to reduce the filling ratio. When experience is available, and figures for tolerances of filling are known, these can be used. Otherwise a value of 2 % is recommended.For example, for a mixture of 30 %/70 % H/L where H is the heavier component, the ratio should be calculated on the basis of 28 %/72 % H/L.

The formula for a mixture of two components x1/y1 of a/b is

whereÔa, Ôb are the densities of liquid phase of components a and b at the reference temperature for filling ratioCa, Cb are the percentage confidence limits for liquid densities of components a and bx1, y1 are the nominal mass fractions of components a and bx2, y2 are the mass fractions of components a and b after correction for tolerances.

The procedure can be extended for mixtures of three or more components.A.1.3 Pressure of mixtures (except hydrocarbon gases). For the purposes of assessing the developed pressure of a mixture of gases, the contents shall be assumed to be 100 % of the component with the highest vapour pressure. However for an azeotrope which develops a pressure higher than any of its individual components the pressure of the azeotrope shall be the value which is to be used.A.2 High pressure liquefiable gasesA.2.1 Filling ratio for single components (see 4.4).A.2.1.1 Two phases. When the design of the container is such that contents when carrying an HP liquefiable gas are in two phases (e.g. cryogenic conditions) then the filling ratio is defined as in A.1.1, except 2 % guaranteed free space is allowed.

A.2.1.2 Single phase. Apart from cryogenic conditions, it is more usual for a high pressure liquefiable gas to be in a single phase at the reference temperature. The pressure developed at a given temperature is dependent on the filling ratio, and must be determined experimentally.The maximum filling ratio is that which produces, at the reference temperature, a developed pressure equal to the test pressure of the container, or equal to such lower value as is appropriate depending on the design of the container.

A.2.2 Filling ratio for mixturesA.2.2.1 Mixtures, which may be of high pressure liquefiable gases alone or with low pressure liquefiable gases, should only be assessed under such conditions as enable formula 3 to apply i.e. the filling ratios used are sufficiently low to ensure two phase conditions (note that the densities used are those of the liquids at the references temperature for developed pressure).A.2.2.2 Higher filling ratios than those obtained under A.2.2.1 may be permissible but should be backed by experimental evidence, and application made under the procedures of Appendix B.A.3 Permanent gasesA.3.1 Mixtures of permanent gasesA.3.1.1 If a mixture has one component of more than 98 % by mass, then the charging pressure may be determined as if the main component were 100 % of the contents.A.3.1.2 For mixtures other than those falling under A.3.1.1 the charging pressure may be determined as if the component with the highest ratio of developed pressure at reference temperature to charging pressure, were 100 % of the contents (except that components present in concentrations less than 0.5 % by mass can be aggregated with the major component).A.3.2 Mixtures of permanent and liquefiable gasesA.3.2.1 If one component is a permanent gas of concentration 98 % or more of the mixture by mass, then the charging pressure may be determined as if the main component were 100 % of the contents.A.3.2.2 For mixtures other than A.3.2.1 approval shall be sought under the procedures of Appendix B.

Appendix B Filling ratios and developed pressures not specified in this standard

For the conveyance by road of gases and gas mixtures where the filling ratios and developed pressures are not specified in this standard, application shall be made to HM Inspectors of Explosives. It may be necessary to support the application with a statement of the relevant chemical and physical properties of these gases or gas mixtures.The data should be supported wherever possible by reference to published papers or by full details of non-published experimental work, and include the effect on the properties of specified limits of impurity in the gas or gas mixture proposed.

The temperature range over which the physical properties are to be submitted should preferably be that indicated in the following table for the class of gas concerned to permit as the case may be, the assessment of the developed pressure/charging pressure at 15 °C relationship for permanent gases or the filling ratio and developed pressure requirement for liquefiable gases.

The procedure for mixtures of gases of the same class should follow the procedure laid down for that class. Mixtures of different classes of gas, including padding with inert gases for conveyance, are special cases, and the fullest information shall be supplied on their behaviour with temperature over the intended range of mixture composition, following the lines indicated in the above table.Where liquefiable gases defined in clause 3 are to be conveyed at sub-normal temperatures in insulated containers, the ranges of temperature applicable for conveyance in exposed naked containers do not apply, since the contents are maintained, by means of insulation and/or some form of refrigeration, at sub-normal temperatures. In such cases the liquid density/temperature and vapourpressure/temperature relationships, inclusive of the effects of any impurity and of any inerts, are required relative to the maximum permissible developed pressure, and these data should be given for a temperature range from 10 °C below the temperature corresponding to the maximum permissible developed pressure to 10 °C above that corresponding to the test pressure for which the container is to be designed.

Appendix C Filling ratios and developed pressure for countries other than the United Kingdom

C.1 This appendix gives details of the filling ratios and developed pressures for liquefiable gases and developed pressures for permanent gases which may be used in the design and filling of containers intended for export of gas from the United Kingdom.Where the containers are to be filled with gas in the country of distribution at the prevailing ambient temperature, the container may be designed using the criteria contained in the body of this standard.Statutory requirements for the conveyance of gas containers in ships or for their conveyance or use in other countries may preclude the use of these data. Those intending to export containers from the United Kingdom, or those intending to supply containers for shipboard use, should therefore ascertain the statutory requirements before using any of the data in this appendix.C.2 Table 17 classifies countries according to the absolute maximum shade temperature attained in those countries.C.3 Table 18 lists the reference temperatures for filling ratios and developed pressures according to the climatic areas given in Table 17.C.4 Filling ratios and developed pressure data for high pressure liquefiable gases at the reference temperatures given in Table 18 are given inTable 19.

C.5 Filling ratio and developed pressure data for low pressure liquefiable gases at the reference temperatures in Table 18 are given in Table 20.NOTE See 5.2.3 for mixtures of low pressure liquefiable gases.

C.6 For mixtures of liquefiable petroleum gases, Table 21 to Table 30 should be used for obtaining filling ratios appropriate to the reference temperature. The density of the mixture should be determined at a convenient temperature, and for any given reference temperature the maximum permissible filling ratio is the value at the intersection of the row beginning with the value determined for the density and the column headed by the temperature at which it was determined.Table 21, Table 23, Table 27 and Table 29 give the maximum permissible filling ratios for mixtures of liquefiable petroleum gases consisting wholly of saturated hydrocarbons.Table 20, Table 24, Table 26, Table 28 and Table 30 give the maximum permissible filling ratios for mixtures of liquefiable petroleum gases consisting wholly of unsaturated hydrocarbons, or containing more than 2 % by volume of C2 hydrocarbons.For mixtures containing both saturated and unsaturated hydrocarbons reference should be made to 5.2.7.C.7 Developed pressure data for permanent gases at the reference temperatures given in Table 18 are given in Table 31.
