IS 9197: Key Material Specifications & Tables

1. Epoxy Resin (Clause 3.1)

• Grade 1 (No diluents):

  Class	Epoxy Content (Eq./1000g)	Weight/Epoxy Eq.	Viscosity @27℃ (Pa.s)	Specific Gravity @27℃	Max Hydrolyzable Chlorine %
  I	5.0 to 5.88	200 to 170	3 to 20	1.05 Min - 1.20 Max	9.0

• Grade 2 (With reactive diluent):

  Class	Epoxy Content (Eq./1000g) Min	Viscosity @27℃ (Pa.s)	Specific Gravity @27℃	Max Hydrolyzable Chlorine %
  I	5	0.5 to 0.9	1.05 Min - 1.20 Max	9.0
  II	5	0.9 to 4	Same as above	0.6
  III	5	4 to 10	Same as above	9.0

IS 9197: Sampling and Criteria for Acceptance

Sampling Procedure (Clause 5.1 & Appendix A)

• Samples must be taken from each lot separately to verify conformity.
• Sampling should follow the procedure detailed in Appendix A of IS 9197.
• Each lot is tested independently.

Criteria for Acceptance (Table A-3, Clause 3.3)

• If the first sample fails the requirements in Table 5, a second sample from the same lot is tested.
• If the second sample also fails, the entire lot is rejected.
• This ensures strict quality control.

Summary Table: Conformity Check

Note:

• Table 5 specifies detailed test requirements for epoxy resin hardeners and compositions.
• Sampling size and frequency are per Appendix A.

    A[Sample Lot] --> B{Test 1st Sample}
    B -- Pass --> C[Accept Lot]
    B -- Fail --> D[Test 2nd Sample]
    D -- Pass --> C
    D -- Fail --> E[Reject Lot]

This approach ensures reliable quality assurance of epoxy resin materials per IS 9197.

IS 9197: Packing and Marking Key Points

Packing (Clause 6.1)

• Resins and Hardeners: Packed separately in sealed airtight containers to prevent contamination and degradation.
• Fillers: Supplied in separate packaging from resins and hardeners.

Marking Requirements (Clause 6.1.1)

Each package must be legibly marked with:

• Manufacturer's name
• Product name
• Date of manufacture or batch number
• Storage requirements
• Storage life
• Date of expiry

BIS Certification (Clause 6.2)

• Products may carry the BIS Standard Mark to indicate conformity with IS 9197.

IS 9197: Sampling Procedure & Conformity Criteria

Sampling Procedure (Clause 5.1, Appendix A)

• Samples are selected from each lot separately to verify conformity (Clause A-1.2).
• If a sample fails, a re-test is done on a fresh sample from the same lot (Clause 3.3).
• If the second sample also fails, the entire lot is rejected.

Conformity Criteria (Table A-3, Clause 3.3)

Additional Notes

• Final test values must be rounded off as per IS 2:1960, matching the significant figures of the specified values (Clause 3.4).
• Purchaser may select options as per Clauses 3.1, 3.2, 3.4, and 3.6 to suit requirements.

    A[Select Sample from Lot] --> B[Test Sample]
    B -->|Pass| C[Accept Lot]
    B -->|Fail| D[Prepare Second Sample]
    D --> E[Test Second Sample]
    E -->|Pass| C
    E -->|Fail| F[Reject Lot]

This ensures quality control by rigorous testing and clear acceptance/rejection rules.
