What types of taps and mixers does this standard cover?

It covers pillar taps, bib taps, angle valves, mixers (mechanical and thermostatic), and self-closing taps (Clause 1).

What is the standard endurance test for a bathroom tap?

200,000 open/close cycles for a single tap and 70,000 cycles for a mechanical mixer (Table 2).

How is the corrosion resistance of chrome-plated taps verified?

Compliant taps must pass a 200-hour Neutral Salt Spray (NSS) test without showing significant corrosion (Clause 9.2 & Table 4).

What is the maximum noise level allowed for a tap?

For Acoustic Group I (low noise), it is 20 dB(A); for Group II, it is 30 dB(A), both measured at 0.3 MPa pressure (Table 3).

This standard specifies the material, dimensional, performance, and testing requirements for various types of taps and mixers used in water supply systems. It aims to ensure durability, water efficiency, and user safety by consolidating and updating several older individual standards into a single comprehensive document.

Specifies general requirements for taps and mixers used in plumbing installations.

Practical Notes

This is a harmonized standard that replaces multiple older IS codes for taps. Always check for the BIS certification mark on the product to ensure compliance.

Pay close attention to the flow rate classification (Table 1) to select water-efficient fixtures, especially for green building projects.

The acoustic group rating (Table 3) is important for projects where low noise is a priority, such as hospitals and premium hotels.
