According to the EPA website, EPA certification test questions address four main categories: core information, small appliances (type 1 certification), high-pressure appliances, (type 2 certification) and low pressure appliances (type 3 certification). Overall, the questions test knowledge of ozone depletion, section 608 laws, recovery requirements (small appliances), leak detection (type 2 certification) and recharging techniques (type 3 certification).
According to the EPA, a universal certification covers all three types of appliances. Core knowledge questions look into aspects such as ozone destruction by chlorine, chlorine in CFC and HCFC refrigerants, alternatives to refrigerants and oil, refrigerant states and refrigeration gauges. With type 2 certification, a candidate will be asked about the definition of “small appliance” and evacuation procedures using recovery devices. Safety issues such as decomposition elements at extreme temperatures are also addressed.
The EPA test for low-pressure appliances is focused on items such as leak test pressurization methods and priorities, maximum leak test pressure, permissible leak rate levels for appliances with more than 50 lbs of refrigerant, recovering liquid, oil-heating requirements before recovery to limit refrigerant release, water circulation or removal from chiller to preempt freezing and evacuation procedures for low-pressure equipment. The test also addresses safety precautions such as room specifications as outlined by ASHRAE Standard 15.Learn More

The EPA offers Type I, Type II, Type III and universal certifications, depending on the type of appliances and equipment technicians use.Full Answer >
As noted by the American Heart Association, BLS, or basic life support, test questions center on providing basic life support in an emergency situation. Areas of focus on a BLS test include CPR, rescue breathing, choking relief and using an automated external defibrillator, or AED, for adults, children and infants.Full Answer >
A welding certification test is a specifically designed examination to determine the ability and skill of an individual in one or several welding processes. Aside from the skills to deposit sound weld metal, the test also examines the participant's knowledge of welding symbols and a welder's duties and responsibilities.Full Answer >
