What is the minimum thickness for a domestic stainless steel sink?

The minimum thickness of the finished sink sheet should be 0.80 mm (Clause 4.2).

What material is specified for sinks under IS 13983?

The sink body must be made of austenitic stainless steel conforming to Grade X04Cr19Ni9 of IS 6911 (Clause 4.1.1).

What are the standard sizes for kitchen sinks?

Table 1 provides various standard overall and bowl dimensions for single/double bowl sinks with or without drainboards. For example, a 610x510 mm single bowl/drainboard sink.

Is there a load test requirement for these sinks?

Yes, the sink bowl must withstand a uniformly distributed load of 1.5 kN on a 100 mm square block for 15 minutes without permanent damage (Clause 10.3).

Practical Notes

Always check for the ISI mark and manufacturer's details on the product, as required by the marking clause (Clause 12).

The specified stainless steel grade (Grade X04Cr19Ni9 of IS 6911, similar to 304 grade) is crucial for corrosion resistance; avoid sinks made from inferior grades.

Verify the sheet thickness is at least 0.80 mm, as thinner sheets are prone to denting and have a less durable feel.
