Reporting & Relation to Paint Product Specifications
IS 101 standardises how paints are sampled and tested; it does not itself set pass/fail limits β those come from the relevant paint product specification. A defensible test report therefore cites the exact IS 101 part/section used, the panel/film-thickness/conditioning regime, and reports the result judged against the product spec's limits.
Key Requirements
β’Cite the exact IS 101 part/section for each property tested (the method), not 'IS 101' generically
β’Report panel type, film thickness, drying/conditioning regime with every result
β’Apply acceptance limits from the paint product specification β IS 101 provides the method, not the limit
β’A non-representative sample (IS 101 Part 1 sampling) invalidates the result regardless of method
β’Treat method (IS 101) and acceptance (product spec) as a chain β both must be cited
Practical Notes
βDisputes over paint test results usually unwind to an ambiguous spec ('IS 101' with no part/section) or an unrecorded panel/thickness/conditioning β the method and the regime must both be on the report.
βIS 101 is the paint analogue of every method standard: it certifies how, the product spec certifies how-much.
Common Mistakes
β Treating IS 101 as if it set acceptance limits (it sets the method only).
β Reports omitting the part/section, panel, film thickness or conditioning.
β Accepting/rejecting paint on a non-representative sample (IS 101 Part 1 sampling not followed).
