The purpose of periodic testing is to ensure the compliance of continued production of a children’s product to all the product safety rules it was first certified for. The CPSC defines periodic testing in their FAQ as, “The general principle set forth in the regulation is that you, as the manufacturer, must have a periodic testing plan and conduct periodic testing (using a CPSC-accepted laboratory) at least once per year.”
Previously tested children’s products or component parts of children’s products do not require periodic testing. If the children’s product or component part of a children’s product was sampled and tested for certification purposes, those test reports remain valid for the remainder of that particular lot or batch of the children’s product or component part of the children’s product.
Continued production or importation of the same children’s product or component part of a children’s product (assuming no material changes that would require re-certification) are subject to the periodic testing requirement.
If a manufacturer/importer of record conducted certification testing on each new lot or batch of a children’s product or component part of a children’s product, that testing would constitute recertification of the finished product or component part and therefore periodic testing requirements would not apply.
Based on the final rule of 16 CFR Part 1107, continuing production of a children’s product or component part of a children’s product would have to select either a representative sample or random sample technique(s) for periodic testing purposes.
