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).Know More
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 in Environmental Science
Heating, ventilation and air conditioning, or HVAC, technicians may obtain an Environmental Protection Agency certification for managing refrigerants by passing an approved test administered by an acceptable certifying organization. The EPA offers Type I, Type II, Type III and universal certifications, depending on the type of appliances and equipment technicians use.Full Answer >
