Analytical Testing (TSCA PBT)

Analytical testing for TSCA PBT compliance involves laboratory analysis to determine the presence and concentration of restricted PBT chemicals in materials or products. Common techniques include XRF for bromine screening (DecaBDE indicator), GC-MS for organic PBT identification, and ICP for elemental analysis. Results are compared against applicable concentration thresholds (e.g., 0.3% for 2,4,6-TTBP, 1% for PCTP).

No official TSCA test method prescribed; industry practice aligned with 40 CFR Part 751 thresholds.

Analytical testing supplements supplier declarations when data is unavailable or verification is needed. Companies should screen high-risk components (flame-retardant plastics, rubber products, lubricants) first. Test reports should be retained for five years.

An electronics OEM sends plastic housing samples for GC-MS analysis targeting DecaBDE and PIP (3:1). Results show DecaBDE at 0.02%—below threshold. The OEM retains the report and requests a formal supplier declaration.
