BIS Certification for Sand Cast Iron Spigot and Socket Pipes, Fittings, and Accessories – IS 1729:2023. 

Sand cast iron spigot and socket pipes, along with their fittings and accessories, are critical components used in non-pressure drainage and sewerage systems across India. To ensure safety, durability, and uniformity, these products must now comply with the latest Indian Standard – IS 1729:2023, as notified by the Bureau of Indian Standards (BIS) on October 20, 2023.

What Is IS 1729:2023?

IS 1729:2023 is the third revision of the earlier IS 1729:2002. It provides detailed specifications for:

Sand cast iron spigot and socket pipes

Pipe fittings and connectors

Accessories required for jointing

This standard covers:

Dimensional and tolerance limits

Chemical composition
