1 Section 608 Core Principles Free Online FlashCards

Which Section 608 certification type covers small appliances?

Type I covers small appliances.

What does Universal Section 608 certification require and cover?

Universal certification requires passing the Core, Type I, Type II, and Type III exams; it covers all three equipment categories.

What environmental impacts do ODP and GWP describe?

ODP describes ozone-depletion impact; GWP describes climate-warming impact. They measure different environmental effects.

What is Section 608's rule on knowingly venting regulated refrigerants?

Knowingly venting regulated refrigerants during service, repair, maintenance, or disposal is prohibited. A limited de minimis release may occur despite good-faith capture efforts.

What does refrigerant recovery mean?

Recovering removes refrigerant from an appliance and stores it in an external container; the refrigerant need not be cleaned or tested.

What is refrigerant recycling, and how does it differ from reclamation?

Recycling cleans recovered refrigerant for reuse, generally in equipment owned by the same person; it does not meet the full reclamation standard.

What makes refrigerant reclamation different from recovery or recycling?

Reclaiming reprocesses refrigerant to required purity specifications and verifies them through required analysis.

What does evacuation remove, and when is it performed?

Evacuation uses a vacuum pump to remove air and moisture after refrigerant has been recovered and the system opened for service.

What can a standing pressure or vacuum-decay test tell you?

A standing pressure or vacuum-decay test may indicate a leak, but it does not locate the leak by itself.

What are the Section 608 leak-repair trigger rates for covered appliances?

For specified appliances containing at least 50 pounds of ozone-depleting refrigerant, trigger rates are 30% for industrial process refrigeration, 20% for commercial refrigeration, and 10% for comfort cooling and other appliances.

What precautions apply when pressure-testing with nitrogen?

Use a regulator and appropriate pressure limits. Never pressure-test with oxygen or compressed air, which can create fire or explosion hazards when mixed with oil or refrigerant.

What are two refrigerant exposure hazards, and how can technicians reduce risk?

Refrigerant can displace oxygen and cause asphyxiation; liquid refrigerant can cause frostbite. Work in well-ventilated areas and wear appropriate eye and hand protection.
