What grade of steel is specified for these stays and fasteners?

The standard specifies mild steel conforming to IS 226, which was the standard for structural steel at the time. An equivalent modern grade from IS 2062 would be E250A.

What are the essential mechanical tests required by this standard?

The key mechanical tests are the Tensile Test (Clause 7.1) and the Bend Test (Clause 7.2) to verify strength and ductility.

Does this standard cover anti-corrosion finishes?

Yes, Clause 5.2 states that the stays and fasteners shall be finished with a suitable protective coating (like plating, painting, or galvanizing) as agreed between the purchaser and manufacturer.

Are the dimensions for all types of stays specified?

Yes, the standard provides dimensional tables (Tables 1, 2, 3) for common types like peg type casement stays, lever type casement stays, and fanlight stays.

Practical Notes

The primary material requirement is conformance to IS 226 (now superseded by IS 2062), ensure material test certificates are available.

Pay close attention to the workmanship and finish clause (Clause 5), ensuring products are free from cracks, burrs, and sharp edges for safety and proper functioning.

Verify the BIS certification mark on the product or packaging as a sign of conformity to this standard.
