On the new Skolnik web site, we recently posted a valuable chart that indicates the current UN Certified products available from Skolnik (http://www.skolnik.com/uncerts.pdf), and the dates that these certifications expire. As a result, we have received many calls inquiring why the certifications expire. Per CFR 178.601(e), the US Department of Transportation allows manufacturer‘s to annually self-certify their products in accordance with 178.601, 178.602, 178.603 (Drop Test), 178.604 (Leakproofness Test), 178.605 (Hydrostatic Pressure Test), and 178.606 (Stacking Test). It is mandatory that certifications are valid on the day a product is manufactured. Once manufactured, the certification is good for the life of the drum. Should a manufacturer choose not to re-certify a product, this only prevents the manufacturer from making this design type. Drums manufactured under valid certification periods are covered for the extent of useful life. It is also important to note that the certification is for the date the product is manufactured, not the date the product is sold. Therefore, if manufactured under a valid UN certification, and at some point in the future, this certification expires; the UN status of the drum is not affected.
