What are the primary applications for IS 1626 Part 1 pipes?

They were historically used for rainwater, soil, waste, and ventilating applications in building drainage systems.

What code dictates the testing methods for these asbestos cement pipes?

Testing methods for asbestos cement products are detailed in IS 5913.

Can these pipes be used for pressurized water supply?

No, these specific pipes are designed for gravity-fed building drainage and ventilation, not for high-pressure water mains.

Practical Notes

Due to the severe health hazards and carcinogenic nature of asbestos fibers, these products are banned or heavily restricted in many jurisdictions. Verify local laws before specifying or handling.

Modern construction overwhelmingly uses UPVC, CPVC, or Cast Iron pipes instead of asbestos cement.

If maintenance, removal, or repair of existing AC pipes is required, strict asbestos abatement protocols and safety gear (as per IS 12059) must be used to prevent fiber inhalation.
