Amendment to Methods of Test for Plywood – IS 1734 (Part 4):1983

Introduction to the Methods of Tests for Plywood

The Bureau of Indian Standards (BIS) periodically revises Indian Standards in order to ensure that testing methods remain aligned with evolving industry practices as well as quality expectations. One such important standard is IS 1734 (Part 4):1983, which specifies the Methods of Test for Plywood, particularly focusing on the Determination of Glue Shear Strength, which is mainly an essential parameter influencing the structural integrity as well as performance of plywood products.

In accordance with Rule 15(1) of the Bureau of Indian Standards Rules, 2018, BIS has issued a notification establishing Amendment No. 4 to this standard.

Now, What to Do?

Plywood manufacturers, BIS license holders, as well as the testing laboratories, should use the concurrent period to review the revised glue shear strength testing requirements and align internal testing protocols accordingly. This includes updating quality control procedures, carefully assessing test equipment, training technical staff, and ensuring laboratory readiness for compliance after August 2024.
