- Note: King County is no longer maintaining a list of approved amalgam separators. If dental practices are using installation of an approved separator to demonstrate compliance with County regulations, King County will only recognize amalgam separators that have been certified as meeting or exceeding ISO-11143 as verified by an ISO-certified testing laboratory. Dental practices must be able to provide a copy of the ISO-11143 certification for their amalgam separator units if requested by King County.
