Indian StandardSPECIFICATION FOR

BALLIES FOR GENERAL PURPOSES

( First Revision)

o. FOR E W 0 R D

0.1 This Indian Standard (First Revision) was adopted by the IndianStandards Institution on 30 January 1978, after the draft finalized by theTimber Sectional Committee had been approved by the Civil EngineeringDivision Council.

0 ..2 BALLIES of various sizes and species of timber are extensively usedfor the construction of scaffolding and for the erection of temporary andsemi-permanent structures. BALLJES are also used in large quantities forfencing work, pile foundation, supports for shuttering and for floodprotection work in the form of permeable spurs and bank piling forpreventing erosion. This standard has, therefore, been prepared with theobject of providing guidance on the sizes and requirements of BALLIES forgeneral purposes.

0.3 This standard was first published in 1965. This is the first revision ofthe standard. In this revision, besides incorporating some modificationsin the provisions relating to preservation, modifications have also beenmade in the limits of permissible defects.

0.4 In the formulation of this standard due weightage has been given tointernational co-ordination among the standards and practices prevailing indifferent countries in addition to relating it to the practices in the field inthis country.

0.5 For the purpose of deciding whether a particular requirement of thisstandard is complied with, the final val ue, observed or calculated, expressingthe resul t of a test or analysis, shall be rounded of in accordance withIS : 2-1960*. The number of significant places retained in the rounded offvalue should be the same as that of the specified value in this standard.

1. SCOPE

1.1 This standard covers the requirements of BALLIES used for generalpurposes.

• Rules for rounding off numerical values (revised ).

3

IS : 3337 - 1978

- 2. TERMINOLOGY

2.1 For the purpose of this standard, the definitions given in IS: 707-1976*and the following shall apply.

2.1.1 Air Dried BALLIES - RALLIES dried in open air, usuallyprotected from the direct action of sun and rain.

2.1.2 BALLIES - Thin round poles usually without bark.

2.1.3 Cross Break - Break or fracture across the grain of the wood.

2.1.4 Curvature - Deviation of a BALLIE from straightness.

2.1.5 Decay - Disintegration of wood tissues caused by fungi (wooddestroying) or other micro-organism. \

2.1.6 Hollow Heart - A cavity in the heart of a BALLIE resulting fromdecay.

2.1.7 Short Crook - A localized deviation from straightness which,within any section of 1'5 m or less in length, is more than one-half the meandiameter of the crooked section.

2.1.8 Spiral or Twisted Grain - Grain in which the vertical elements arealigned spirally in the bole of a standing tree or a log.

3. SPECIES OF TIMBER

3.1 The species of timber suitable for BALLIES are given in Appendix A.

3.2 Other species not included in Appendix A shall not be supplied withoutthe prior approval, in writing, of the indentor/user.

4. MANUFACTURE

4.1 Unless otherwise specified, the bark shall be completely removed andall the branches and excrescences shall be dressed down flush with thesurface. The top and bottom ends shall be cut square.

5. DIMENSIONS

5.1 Unless otherwise 'ordered', the BALLIES shall' conform to thedimensions given below:

Class of Diameter at the Top Diameter at the Butt End LengthBALLIES

6. REQUIREMENTS

6.1 BALLIES shall be air-dried to a moisture content not exceeding 20percent within a depth of 12 mm from the surface when measured at one­third length of the BALLIES from its butt end.

6.2 BALLIES shall be reasonably straight, and shall be free from cutsacross the grain, live insect attack, any kind of decay (rot), pronouncedspiral or twisted grain, hollow heart and dead knots exceeding 5 em indiameter.

7. PERMISSIBLE DEFECTS

7.1 Surface Cracks - These shall not exceed 20 mrn in depth and 3 mm inwidth for Class 1 RALLIES, and not exceed 12 rnm in depth and 3 mrn inwidth for Classes 2 and 3 BALLIES provided they are not so numerous orso located as to impair the usefulness of the RALLIES.

7.2 End Cracks - The longest end crack at each end shall be measured andthe lengths added together. The total length of the longest cracks shallnot exceed 30 em irrespective of the length of the BALL/E.

7.3 Spiral or Twisted Grain - There shall not be more than one completetwist of grain or spiral in any 6 In of length.

7.4 Curvature - BALLIES shall be so straight that when laid horizontally inany position, the centre line joining the apex and base shall not deviatefrom the actual axis of the BALLIES by more than 7' 5 em.

7.5 Short Crooks - These shall not exceed two in number per BALLIE.

7.6 Pin Hole (Dead Infestation) - These shall be scattered and notconcentrated, provided they are not due to powder post beetles.

8. MEASUREMENTS

8.1 Length - The length shall be measured between the extreme ends ofBALLIES. BALLIES shall not be more than 7'S ern shorter or more than15 em longer than the 'ordered' length.

8.2 Diameter - The top and butt end diameters shall be measured at theextreme ends of the BALLIES.

9. PRESERVATION

9.1 Whenever required the entire BALLIE or the butt ends up to thespecified length shall be preserved by dipping. brushing or spraying withanyone of the following compositions (see also IS:401-1967* ):

a) Creosote-fuel oil mixture 50: 50,

b) 6 percent solution of copper-chrome-arsenic composition,

.Code of practice for preservation of timber ( second revision ).

IS : 3337 - 1978

c) 6 percent solution of acid-cupric-chromate composition,

d) 8 percent solution of copper-chrome-boric composition, and

e) 1·0 percent solution of sodium pentachlorophenate.

10. MARKING

10.1 Each BALLIE shall be legibly and indelibly marked with the followinginformation at a distance of 2 m from the butt end of the BALLIE:

a) Species of timber by symbol ( see Appendix A ),

b) Class of BALLIE, and

c) Supplier's name or initials or registered trade-mark, if any.

10.1.1 The BALLIE may also be marked with the lSI CertificationMark.

NOTE - The use of the lSI Certification Mark is governed by the provisions of theIndian Standards Institution (Certification Marks) Act and the Rules and Regulationsmade thereunder. The lSI Mark on products covered by an Indian Standard conveysthe assurance that they have been produced to comply with the requirements ofthat standard under a well-defined system of inspection, testing and quality controlwhich is devised and supervised by lSI and operated by the producer. lSI markedproducts are also continuously checked by lSI for conformity to that standard as afurther safeguard. Details of conditions under which a licence for the use of the lSICertification Mark may be granted to manufacturers or processors, may be obtainedfrom the Indian Standards Institution.
