Practical Notes

This standard has been withdrawn by BIS. However, its specifications can still be used as a quality benchmark for manufacturing or procurement.

Ensure timber is properly seasoned to the specified moisture content (12±3%) to prevent future warping or cracking.

The folding mechanism is a critical component; check for smooth operation and robust construction during inspection.
