ISO , , Accredited Laboratory. Over the course of more than 35 years, we have built a well-earned reputation as one of the leading international commercial testing services in the world; including the BSS Toxicity Test. Commonly abbreviated to BSS, the BSS is a test method for the generation of toxic gases by specific materials upon combustion. When materials burn or ignite, they release gases that can be hazardous to human health when they reach certain levels. BSS determines exactly which and how much toxic gases are emitted by burning a sample piece of material of three inches by three inches in a controlled setting.
