IS 7834:2000 (Part 3) is the Indian Standard (BIS) for injection moulded pvc socket fittings with solvent cement joints for water supplies, part 3: specific requirements for 90-degree elbows. This standard specifies the material, dimensional, and performance requirements for injection moulded PVC caps designed for solvent cement joints in water supply pipelines. It is a part-specific standard and must be read in conjunction with IS 7834 (Part 1) for general requirements and test methods.
