Foreword

This European Standard has been prepared by Technical Committee CEN /TC 218, "Rubber and plastics hosesand hose assemblies", the secretariat of which is held by BSI.

This European Standard shall be given the status of a national standard, either by publication of an identical text orby endorsement, at the latest by March 2002, and conflicting national standards shall be withdrawn at the latest byMarch 2002.

This standard is one in a series of specifications for hose and hose assemblies for conveying petroleum based andassociated products. It covers types of hose and hose assemblies for conveying asphalt and bitumin, which arehazardous materials at temperatures where they can flow readily.

The annexes A, B and C are normative. Annex D is informative.

According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden,Switzerland and the United Kingdom.

1 Scope

This European standard specifies requirements for two types of hose and hose assembly identified by theirmaximum working pressures and main use i.e. Type 1 is for road and rail tanker use and Type 2 is for docksideuse. The types can be further divided into two classes related to the maximum temperature of the product to beconveyed. The hose constructions may be smooth or rough bore.

NOTE These types of hose or hose assemblies may not necessarily be suitable for all types of petroleum based productsor coal tar, or products containing coal tar.

2 Normative references

This European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the test and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision. For undated references the latest edition of thepublication referred to applies (including amendments).

9 Frequency of testing

Type approval and routine tests are specified in Table C.1.

Type approval tests are those tests required to obtain type approval.

Routine tests are those tests that must be carried out on all hose assemblies prior to dispatch.

Production acceptance tests are specified in table D.1 and are the recommended frequency of routine tests thatshould be carried out by the manufacturer to control the quality of his manufacture. This frequency specified inannex D is a guide being an informative annex only.

10 Marking

10.1 Hoses

At least the following information shall be permanently and legibly marked on the hose cover either in one positionat one end of the hose and at 180° opposed to that position at the opposite end of the hose, or alternativelycontinuously along the length.

a) manufacturer’s name or trademark, e.g. MAN;

b) the number and year of this European Standard;

c) type and class of hose, e.g. Type 1 SB/A;

d) internal diameter;

e) maximum working pressure, in bar;

f) maximum working temperature, e.g. 175 °C;

g) quarter and year of manufacture e.g. 3Q01

h) asphalt and bitumen.

EXAMPLE: MAN – EN 13482:2001 – type 1 SB/A/150 – 7 bar – 175 °C – 3Q01/ASPHALT and BITUMEN.

10.2 Hose assemblies

Fittings should be marked with the manufacturers trademark. Hose assemblies should be marked with the hoseassemblers mark and the date of assembly.

Annex A (normative)

Test method for proof pressure

A.1 Test medium and temperature

The test medium shall be water, and the temperature at which the test is conducted shall be between 10 °C and30 °C.

A.2 Procedure

The hose assembly shall be laid out as straight as possible, filled with water and vented to remove all trapped air.The hose shall be free to expand and contract without restraint.

Carry out the following sequence:

raise pressure to 0,7 bar and measure the overall length of the assembly;

a) raise to half the proof pressure (see Table 3 depending on type) over 5 min and hold for 10 min;

b) reduce pressure to zero over 5 min;

c) raise to full proof pressure (see b) above) over 5 min and hold for 10 min;

d) measure the overall length at proof pressure to ascertain the temporary elongation; record as apercentage of the original length measured at 0,7 bar;

e) reduce pressure to zero over 5 min;

f) after an interval of at least 15 min and not more than 30 min, raise the pressure to 0,7 bar;

g) measure overall length at 0,7 bar to ascertain permanent elongation. Record as percentage of originallength measured at 0,7 bar.

Annex B (normative)

Test method for bend and burst pressure

Following the non-destructive testing of Table 3, points 1-4, carry out the following test:

a) bend the hose to its minimum bend radius (see Table 1) and while in the bent position carry out thehydrostatic pressure procedure as described in annex A, omitting the measurement of elongation;

b) release the hose from the bent position and increase the pressure over a period of 15 min to theminimum burst pressure as specified in Table 3;

c) maintain this pressure for 15 min and then further increase the pressure until the hose bursts;

d) record the pressure at which the hose bursts and the mode of failure.

The fittings shall not leak up to and at the proof pressure and shall remain in place up to and at the minimum burstpressure.
