Under EPA code 608, the U.S. Environmental Protection Agency requires individuals performing maintenance, service or repair involving the possibility of controlled refrigerants being released into the atmosphere to pass a certification test prior to opening containers or systems using the substances. Four different certifications exist.
Type I certification is primarily for small appliance repair. Type II certification is for technicians working on high-pressure systems such as residential and supermarket refrigeration, and Type III certification is for low-pressure refrigerants. Universal certification means a technician has passed all three certification types. Each type of EPA certification has a different test.
