Frequently Asked
Popular Questions About IS 5806
?Which non-coniferous timber species are authorized for use in ammunition boxes according to this standard?▼
The standard lists specific non-coniferous timber species suitable for ammunition box production in its Appendix A, as referenced in Clause 3.1. These species are selected to meet the durability and strength requirements for defense packaging. For exact species names, Appendix A of the standard should be consulted directly.
?What are the allowed dimensional tolerances for timber planks and scantlings?▼
Clause 4.2 of the standard permits width tolerances of +5 mm and -2 mm, with the negative tolerance not exceeding 10% of total supply. Thickness may vary by +3 mm and no negative tolerance. When specific width ranges are specified, minus tolerance on minimum and plus tolerance on maximum widths are disallowed, ensuring adherence to ordered sizes.
?What kinds and sizes of knots and cracks are acceptable in timber used for ammunition boxes?▼
According to Clause 7.4.1, live knots up to 15 mm in diameter are allowed provided they are not clustered or excessive. Larger knots over 15 mm are limited to one per 750 mm length, with size constraints depending on plank width. Cracks are permitted within defined width and length limits, ensuring structural integrity is maintained.
?What preservative treatments are mandated for sapwood and heartwood in timber?▼
Clause 9.1 requires all timber containing sapwood to undergo preservative treatment conforming to absorption criteria specified in Group 5 of Table 2 in IS 401-1967. Sapwood is only permitted if treated accordingly, while heartwood treatment is not explicitly detailed but generally follows standard preservation practices. End coating to prevent splitting is also specified under Clause 10.1.
?How must timber be branded and marked to ensure traceability?▼
Each timber piece must bear a clear and permanent brand showing the supplier's name, initials, or registered trademark along with the year of supply, as per Clause 8.1. The branding should be of a size that guarantees easy identification, supporting quality control and traceability.
