Can these boards be used for structural or load-bearing purposes?

No, asbestos cement building boards are strictly designed for non-load bearing applications like partitions and false ceilings.

What code dictates the testing methodology for these boards?

The physical and mechanical tests must be conducted in accordance with IS 5913 (Methods of test for asbestos cement products).

What is the typical thickness tolerance allowed?

It generally varies depending on the nominal thickness, but typically falls within ±10% or ±1.5 mm, whichever is less, as per the dimensions clause.

Practical Notes

Health Hazard: Asbestos is a known carcinogen. Cutting, drilling, or sanding these boards releases hazardous fibers and requires strict compliance with occupational safety and health regulations.

These boards are largely being phased out and replaced by asbestos-free fiber cement boards (covered under IS 14862).

Boards should always be stored flat on a smooth, dry surface and supported on timber bearers to prevent permanent deformation or warping.
