Is compositing allowed for testing for lead in the surface paint/coating or in the substrates (that is the underlying materials that are painted or coated)?
The term compositing could refer to more than one type of combination. One type of compositing that labs have used is to combine like paint from several like parts or products to obtain a sufficient sample size for analysis where there is not sufficient quantity of paint on one item to perform the testing. This is appropriate in this circumstance and may even be necessary to obtain valid analytical results. Another type of compositing is to combine different paints or substrates from one or more samples to reduce the number of tests run. This type of composite testing may fail to detect excessive levels of lead in one individual paint or substrate because they have been diluted. This approach is therefore not acceptable. Back to FAQ Page Under 16 CFR 1303.2, electroplating is exempt from the ban on lead containing paint and similar surface coating materials, is this the same under the new statute? Would electroplating a substrate allow the substrate to be considered “inaccessible”?
