What is the acceptable moisture content for commercial veneers?

The moisture content must be between 5% and 15% when tested according to IS 1734 (Part 1) (Clause 8.1).

What are the standard thicknesses available under this IS code?

The code specifies nominal thicknesses from 0.5 mm to 3.0 mm (Clause 6.1).

What is the tolerance allowed on the thickness of a veneer sheet?

A tolerance of ± 5% is permitted on the specified nominal thickness (Clause 6.1.1).

Does this standard cover decorative veneers used for high-end furniture?

No, this standard is for Type II (Commercial) veneers. Decorative veneers (Type I) are covered by IS 1328.

This standard specifies the requirements for commercial veneers (Type II) sliced or rotary-cut from various timber species. It covers classification, materials, dimensions, tolerances, permissible defects, and moisture content to ensure quality for general purpose applications like manufacturing plywood, blockboards, and furniture.

Practical Notes

This standard specifically covers Type II (Commercial) veneers, not Type I (Decorative) veneers which are judged primarily on aesthetic appearance.

Moisture content is a critical parameter affecting dimensional stability. Veneers should be tested upon receipt and stored in a controlled environment to prevent warping or splitting.

Always visually inspect veneers for permissible defects as listed in Table 1, such as knots, splits, and stains, as these can affect the final product's strength and appearance.
