Correct answer: B. Measure the recovered refrigerant and display the quantity, accurate to within 30 g (1.0 oz)

Correct. Appendix C, section 7.1.3, requires that the recovered refrigerant be measured and the quantity displayed, accurate to within plus or minus 30 g (1.0 oz).

• A: Appendix C makes measurement and display a requirement.
• C: A printed receipt is not required by the standard.
• D: No automatic reporting to EPA exists.

Correct answer: C. SAE J1771

Correct. Appendix C, section 6.1.1, states that equipment having refrigerant identification capability shall meet the requirements of SAE J1771, the refrigerant identifier standard.

• A: SAE J639 covers MVAC system safety and service labeling, not identifier performance.
• B: SAE J2099 is the purity standard for recycled HFC-134a referenced in Appendix C, not the identifier standard.
• D: SAE J2196 covers service hoses.

Correct answer: D. January 1, 2008

Correct. 82.36(a)(4) reads: effective January 1, 2008, equipment that recovers and recycles HFC-134a, and equipment that also recharges, must meet Appendix C based on SAE J2788.

• A: November 15, 1992 is the effective date of the class I and II sales restriction in 82.34(b).
• B: March 6, 1996 is the substantially-identical purchase cutoff in 82.36(b)(1).
• C: January 1, 2018 is the self-sealing valve date for small cans in 82.154(c)(2).

Correct answer: D. Higher rates of skin cancer and cataracts in humans

Correct. Increased UV-B exposure is linked to skin cancer, cataracts, suppression of the immune system, and damage to crops and marine life, which is why 82.40(a)(2)(iii) requires the test to cover the adverse effects of ozone depletion.

• A: Ozone depletion has no beneficial effect on engine emissions.
• B: Earthquakes are geological and have no connection to UV radiation.
• C: UV radiation does not lower sea levels.

Correct answer: A. The technician must be trained and certified by a technician certification program approved by EPA under 40 CFR 82.40

Correct. 82.34(a)(2) bars anyone servicing an MVAC for consideration from performing service involving refrigerant unless that person has been trained and certified by an approved program.

• B: Certification is personal. 82.34(a)(2) applies to the person performing the service, and 82.42(b)(2) requires records that every operator of the equipment is certified.
• C: Since November 15, 1995 the definition of refrigerant in 82.32(f) includes substitute refrigerants, so R-134a work is covered exactly like CFC-12 work.
• D: The rule sets no volume threshold. One paid job involving refrigerant triggers the requirement.
