编号：G/TBT/N/USA/1594/Add.1

标题：平流层臭氧的保护：汽车空调系统维修

机构：环境保护署（EPA）

行动：最终规则

摘要：美国环境保护署（EPA）正在采用SAE国际（SAE）制定的三项技术标准，用于回收、再循环和/或再充注机动车空调（MVACs）中的制冷剂2,3,3-四氟丙-1-烯（HFO-1234yf或R-1234yf）。

这三个标准是SAE J2843、SAE J2851和SAE J3030。本规则采用这些标准的最新版本，通过引用将其纳入《清洁空气法》（CAA）第六篇的规定中。这将为希望选择符合这些标准的回收和再循环设备的行业利益相关者提供额外的灵活性。

日期：本最终规则于2021年4月23日生效，即《联邦公报》公布后30天。自2021年4月23日起，《联邦公报》局长批准通过引用纳入规则中所列的某些出版物。

Protection of the Stratospheric Ozone: Motor Vehicle Air Conditioning System Servicing

AGENCY: Environmental Protection Agency (EPA)

ACTION: Final rule

SUMMARY: The Environmental Protection Agency (EPA) is adopting three technical standards developed by SAE International (SAE) for equipment that recovers, recycles, and/or recharges the refrigerant 2,3,3,3- Tetrafluoroprop-1-ene (HFO-1234yf or R-1234yf) in motor vehicle air conditioners (MVACs).

The three standards are SAE J2843, SAE J2851, and SAE J3030. This rule adopts the most current versions of these standards by incorporating them by reference into the regulations under Title VI of the Clean Air Act (CAA). This will provide additional flexibility for industry stakeholders that wish to select recovery and recycling equipment certified to these standards.

DATES: This final rule is effective on 23 April 2021, 30 days after publication in the Federal Register. The incorporation by reference of certain publications listed in the rule is approved by the Director of the Federal Register as of 23 April 2021.
