  • Part 5 Specific Requirements for 45-degree tees
  • Part 6 Specific requirements for sockets
  • Part 7 Specific requirements for unions
  • Part 8 Specific requirements for caps

Each type of fittings is categorized into the following groups based on size:

The fitting shall be subjected to the following test:

  1. Test required
  2. Stress relief test
  3. Opacity test
  4. Effect on water
  5. Short term hydraulic test
  6. Dimension test
