Summary

IS 2530 provides standardized methods for sampling paints, varnishes, and related products. It specifies how to select containers from a lot, how to extract representative samples, and how to prepare samples for testing per IS 101.

Methods for sampling paints, varnishes, lacquers, enamels, and related products from drums, cans, and tanks for testing purposes.

Practical Notes
! Always stir/shake the container thoroughly before sampling — paint settles and top samples are not representative.
! Use clean, dry containers for samples — any contamination invalidates test results.
! Sample from minimum √n containers (square root of lot size) as per Table 1.
! For dispute resolution, keep a sealed reference sample from the same lot.
