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.
