MET’s Product Safety Categories & Standards

MET Laboratories is the nation’s first Nationally Recognized Testing Laboratory (NRTL) – a responsive and recognized leader for manufacturers seeking North American product safety certification.

The MET Laboratories product safety certification mark on a product is recognized by federal and local authorities having jurisdiction, the retail community, project managers, and the consumer as a product meeting the mandated requirement of compliance to applicable national safety standards.

MET Laboratories’ NRTL status is the culmination of MET’s determined effort to have the federal government create a fair and open market for product safety certification laboratories.

MET currently has OSHA approval to test and certify to over 180 product categories. Click below to view these categories.
