IS 10150:1982 is the Indian Standard (BIS) for plastic cisterns for water closets. This standard specifies the requirements for materials, construction, workmanship, dimensions, and performance of plastic flushing cisterns for water closets. It covers low-level and high-level types, including single and dual flush mechanisms, and details the testing procedures to verify their durability and functional efficiency.
Covers requirements for plastic cisterns used with water closets, including material, construction, and functional aspects.
BIM-relevant code. See the BIM Hub for ISO 19650, IFC, and LOD/LOIN frameworks used alongside it.
| Parameter | IS Value | International | Source |
|---|---|---|---|
| Endurance Test (Mechanism/Flush Valve) | 10,000 cycles | 50,000 cycles | BS EN 14055:2018 |
| Endurance Test (Inlet Valve) | Not separately specified (covered under 10,000 cycles) | 200,000 cycles | BS EN 14055:2018 |
| Flush System Type | Single flush (5, 7.5, or 10 litres) | Dual flush is standard (e.g., 4.5/3 L or 6/3 L) | AS 1172.2-2014 |
| Acoustic Performance (Noise during fill) | Not specified | Specified in classes, e.g., Class I: ≤ 20 dB(A) | BS EN 14055:2018 |
| Overflow Rate (Minimum) | 0.25 litres/second | 0.4 litres/second | BS EN 14055:2018 |
| Static Load Test on Body | 90 kg load for 1 hour | 1000 N (~102 kg) for 1 hour (on specified points) | BS EN 14055:2018 |
| Impact Resistance | Drop test with 135g steel ball from 1.2m height | Not directly comparable; performance is ensured via other durability and mechanical strength tests. | BS EN 14055:2018 |
