Testing Overview of The Speclalty Acrylate/Methacrylate (SAM) Panel

摘要

The Specialty Acrylates and Methacrylates Panel ("SAM") was formed at the Chemical Manufacturers Association in March 1987 to address concerns raised by EPA on both existing and new specialty acrylates and methacrylates. Membership in the pnael is open to all producers, importers, formulators and users ofthese chemicals. The purpose of the SAM Panel is two-fold: to remove the restrictions on innovation caused by EPA's regulatory position on new SAM chemicals under TSCA Section 5; and to avoid or modify EPA's mandatory testing requirements on SAM chemicals under TSCA Section 4. On June 19, 1989, SAM and EPA reached agreement on a research and regulatory program. Under this program SAM conducted toxicity screening tests to better understand the structure activity relationships between acrylate and methacry-late subcategories and possible carcinogenic effects. In return, EPA did not proceed with a TSCA Section 4 Test Rule. In addition, if the bioassay on the methacrylate shows no evidence of cancer, EPA may eliminate all concern over potential carcinogenicity of methacrylates.
