IS 1626 Part 2: Sampling and Number of Tests

1. Scale of Sampling (Clause 6.1 & 6.1.2)

Sampling is done by selecting gutters randomly from a lot based on lot size:

2. Number of Tests (Clause 6.2)

• Tests are conducted on the sampled gutters to verify compliance.
• The number of tests corresponds to the sample size selected.
• Final test results should be rounded off according to IS 2:1960 rules, maintaining the same significant figures as specified in the standard.

3. Rounding Off (IS 2:1960)

• Round off the test results to the number of decimal places or significant figures as specified.
• Ensures consistency and accuracy in reporting test outcomes.

This ensures statistically valid sampling and reliable quality control for gutters under IS 1626 Part 2.

Manufacturer's Certificate - IS 1626 (Part 2):1994

• Clause 7 mandates the manufacturer to ensure asbestos cement gutters comply with the standard.
• Upon request, the manufacturer must provide a certificate of conformity to the purchaser or representative.
• The certificate confirms compliance with:
  • Dimensional tolerances (see Tables 2, 3, 4 for Valley, Boundary Wall, Half Round Gutters)
  • Visual defect inspection and impermeability tests (Clause 6.2.1)
  • Material specifications referenced in Annex A (e.g., IS 269, IS 455, IS 5913)

Key Dimensions (Tables excerpt)

Summary for Manufacturer's Certificate:

• Certify gutters meet dimensional tolerances and quality tests.
• Confirm adherence to IS 1626 Part 2 and related referenced standards.
• Provide safety rules sheet with delivery as per IS 11769 (Part 1).
