ISO 13043:2011仅限于为乘用车中的乘客舱、电池等提供冷却或加热的制冷剂系统。它提供了这些系统的制冷剂密封和安全要求的最低设计要求。 ISO 13043:2011解决了仅使用R？134a，R？1234yf和R？744车辆原始设备制造商（OEM）和售后市场（非OEM）提供的组件和系统中的制冷剂。 与这些制冷剂系统相关的相关风险是: 由于高压系统造成的碎片或流体的投射； 吸入有毒物质，包括潜在的分解产物； 火焰传播。 因此，ISO 13043:2011将解决与涉及制冷剂系统的任何这些危害相关的部件和系统设计要求。ISO 13043:2011不涵盖涉及供暖、通风和空调（HVAC）系统的其他部件（加热器、鼓风机、空气混合和分配）或与制冷剂系统无关的任何其他车辆部件的任何情况。 ISO 13043:2011的目的是确保最终用户或服务技术人员在汽车的正常使用、维护和修理以及报废处置过程中不会暴露于危险之中。因此，ISO 13043:2011不涵盖制冷剂的制造、储存和运输，以及装配厂中的制冷剂分配和灌装机。对于这些情况，合格人员的安全将通过行业中常用的现有标准和相关法规来解决。考虑了整个车辆寿命来解决耐久性问题。 为了R？134a体系，ISO 13043:2011适用于文件发布一年后推出的任何新型号类型。 为了R？1234yf和R？744 systems，ISO 13043:2011从这些制冷剂首次应用到任何车辆开始适用。

ISO 13043:2011 is restricted to refrigerant systems providing cooling or heating of passenger compartment, battery, etc., in passenger motor vehicles. It provides minimum design requirements for refrigerant containment and safety requirements of these systems. ISO 13043:2011 addresses the use of only R？134a, R？1234yf and R？744 refrigerants in vehicle original equipment manufacturer (OEM) and aftermarket (non-OEM) supplied components and systems. The relevant risks associated with these refrigerant systems are:

• projection of fragments or fluid due to high pressure systems;
• inhalation of toxic substances, including potential decomposition products;
• flame propagation.

Consequently, ISO 13043:2011 will address the component and system design requirements related to any of these hazards where the refrigerant system is involved. Any scenario involving other components from the heating, ventilation and air conditioning (HVAC) system (heater, blower, air mixing and distribution) or any other component of the vehicle not related to the refrigerant system will not be covered in ISO 13043:2011. The purpose of ISO 13043:2011 is to ensure that end-users or service technicians are not exposed to hazards during normal usage, maintenance and repair, and end-of-life disposal of the car. Therefore, manufacturing, storage and transportation of the refrigerant, as well as refrigerant distribution and filling machines in the assembly plant will not be covered in ISO 13043:2011. For these situations, the safety of qualified personnel will be addressed by existing standards commonly used among the industry and relevant regulations. Entire vehicle lifetime has been considered to address durability issues. For the R？134a system, ISO 13043:2011 applies to any new model type launched one year after the document is published. For the R？1234yf and R？744 systems, ISO 13043:2011 applies from first application of these refrigerants to any vehicle.
