A coating formulation survives 1,000 hours in an accelerated UV weathering chamber without visible failure. Does that mean it will last five years outdoors? No. Laboratory weathering hours cannot be converted into outdoor service years using a universal formula. Accelerated weathering is valuable for comparing coatings, identifying potential degradation mechanisms and screening changes in raw…

A supplier's certificate of analysis reports “Not Detected” for a trace metal. Another laboratory reports a measurable concentration of the same impurity. Before rejecting the shipment or questioning either laboratory, the buyer needs to establish one thing: how low a concentration each method could reliably detect and measure. “Not Detected,” often abbreviated ND, does not…
