EPA 608 Practice Test

Take this free EPA 608 practice exam to see the types of questions that will be on an actual EPA 608 certification exam.

The Federal Clean Air Act, under Section 8, requires persons working with regulated refrigerants to be certified.

There are four types of certification:

Type I - limited to small appliances (5 lbs. or less refrigerant)

Type II - limited to medium, high and very high pressure appliances

Type III - limited to low pressure appliances

Universal - for persons who hold all Type I, II and III certificaitons
