在维修制冷剂系统时，客车和轻型卡车中使用的移动空调（MAC）系统受这些SAE标准的保护。需要对技术人员进行培训，以确保使用推荐的程序对使用R-12、R-134a、R-1234yf、R-744和R-152a制冷剂的MAC系统进行服务和维修。本标准中详细说明了每种制冷剂的独特要求。技术人员可以接受任何或所有制冷剂的培训。技术人员应接受培训，以识别正在处理的制冷剂以及如何安全处理，并配备这些制冷剂特有的基本信息、适当的设备和工具。本标准概述了此类培训计划的最低内容要求。根据本标准设计的培训计划不旨在确保或评估技术人员在机动车空调诊断和维修方面的技术技能。相反，此类计划的目标是向技术人员提供有关安全处理制冷剂和控制服务期间排放的信息。

Mobile air conditioning (MAC) systems used in passenger cars and light duty trucks are covered by these SAE Standards when servicing the refrigerant system. Technician training is required to ensure that recommended procedures are used for service and repair of MAC systems using R-12, R-134a, R-1234yf, R-744, and R-152a refrigerants. Unique requirements for each refrigerant are detailed within this standard. Technicians may be trained in any or all refrigerants. The technician shall be trained to recognize which refrigerant is being handled and how to handle it safely, and be equipped with the essential information, proper equipment, and tools which are unique to these refrigerants. This standard outlines minimum content requirements for such training programs. Training programs designed in accordance with this standard are not intended to ensure or assess the technical skills of technicians regarding the diagnosis and repair of motor vehicle air conditioners. Rather, the goal of such programs is to provide information to technicians about safely handling refrigerants and control of emissions during service.
