Verify Compliance Regarding Key Hazardous Substances
Check against major global regulatory lists to test for substances explicitly restricted by the RoHS Directive-such as lead, mercury, cadmium, hexavalent chromium, PBBs, and PBDEs-and confirm that their levels fall below the maximum concentration limits prescribed by regulations.
Screen for PBT (Persistent, Bioaccumulative, and Toxic) and CMR (Carcinogenic, Mutagenic, or Reprotoxic) substances; additionally, ensure that flame retardants recently restricted or banned by Canada and the EU-such as DP, DBDPE, and PFAS-do not exceed limits applicable to unintentional trace impurities.
Verify Environmental Friendliness Across the Full Lifecycle
Confirm that the flame retardant minimizes environmental release throughout the entire process-from raw material extraction and production/transport to downstream use and recycling-and entails low energy consumption and pollutant emissions during production. Furthermore, ensure it facilitates subsequent recycling and treatment without persisting in the environment or bioaccumulating in organisms.
Conduct combustion characteristic tests-using methods such as limiting oxygen index (LOI) analysis and vertical burning tests-to verify low smoke and low toxicity during combustion, ensuring no significant release of highly toxic, persistent pollutants like dioxins or furans, and no risk of severe secondary pollution.
