本SAE信息报告的范围是对汽车空调系统上使用的端口和工具进行评估，以在车辆服务期间使用经批准的制冷剂排空和加注系统。2021 4月成立了一个工作组来进行这项评估，并于2021 9月结束了工作。工作队的工作范围是评估维修车间报告的问题，这些维修车间有空调维修端口，以及用于连接这些端口的工具。工作组还评估了已发布的SAE J标准，发现其中许多标准不包括维修端口和工具的必要要求。 工作队公布了其调查结果和建议的最后报告。该报告包括纠正和发布与本项目范围相关的新SAE标准的建议。

The scope of this SAE Information Report is an evaluation of the ports and tools used on automotive air-conditioning systems to evacuate and charge systems with approved refrigerants during vehicle service. A task force was formed in April 2021 to perform this evaluation and concluded its work in September 2021. The scope of the task force was to evaluate issues being reported from service repair shops with air-conditionings service ports and the tools being used to connect to these ports. The task force also evaluated published SAE J Standards and discovered many of these standards did not include the necessary requirements for service ports and tools. The task force published a final report of its findings and recommendations. The report includes recommendations to correct and publish new SAE Standards related to the scope of this project.
