标准摘要
[中文适用范围]： 本部分 ISO 10263 规定了一种用于测量在特定环境条件下运行的供暖、通风和空调（HVAC）系统对操作员环境温度贡献的标准化测试方法。该方法可能无法确定操作员完整的微气候环境，因为这也受到机器外部热源（例如太阳辐射加热）的影响。为了更准确地确定操作员封闭空间的完整热负荷，应结合使用 ISO 10263-6。本部分 ISO 10263 建立了机器操作员封闭空间供暖、通风和空调系统的最小性能水平。 注：HVAC 也称为气候控制系统。 [外文原描述]： ISO 10263-4:2009 specifies a uniform test method for measuring the contribution to operator environmental temperature provided by a heating, ventilating and air conditioning system operating in a specific ambient environment. The method might not determine the complete climatic environment of the operator since this is also affected by heat load from sources other than those on the machine, for example solar heating. ISO 10263-6 is to be used in conjunction with ISO 10263-4:2008 to determine more accurately the complete heat loading on the operator enclosure. Minimum performance levels for the machine's operator enclosure heating, ventilating and air conditioning systems are established in ISO 10263-4:2008.
