4. VERIFICATION
4.1 Classification of inspections. The inspection requirements specified herein are classified as
conformance inspection (see 4.2).
4.2 Conformance inspection.
4.2.1 Conformance inspection of filled containers. Each sample filled container, as specified in
4.3.2, shall be examined for defects of the closure and for evidence of leakage. Each filled
container shall also be weighed to determine the amount of contents. Any container having one
or more defects or not filled as required shall be rejected and the lot (see 4.3.1) represented by
the container shall be rejected.
4.2.2 Testing for lot conformance tests. The samples selected in accordance with 4.3.3 shall be
subjected to all the tests specified in 4.4. Acceptance of the wax emulsion shall be based upon
compliance of the material with the requirements of this specification.
4.3 Sampling.
4.3.1 Lot. For purposes of sampling and testing, a lot shall consist of one batch of wax
emulsion, produced by one manufacturer, in accordance with the same specification revision.
Each batch shall consist of that quantity of wax emulsion that has been subjected to the same unit
chemical or physical mixing process intended to make the final product homogeneous.
4.3.2 Sampling of filled containers. Samples shall be selected at random from each lot in
accordance with ASQC-Z1.4 to verify compliance with this specification in regard to fill, closure
and other requirements.
