IEC指南117:2010（E）提供了评估任何人因接触电工设备的热接触表面而烧伤风险的指南。规定了表面温度限值（如有要求），并描述了任何人在不暴露于烧伤风险的情况下与热表面的最大接触时间。描述了具有不同表面类型的不同类型材料的最高温度与接触时间的曲线。技术委员会在确定产品标准中的表面温度极限时，应考虑这些温度极限值。

IEC Guide 117:2010(E) provides guidance for assessing the risk, to any person, of a burn from contact with hot touchable surfaces of electrotechnical equipment. Establishes surface temperature limits, where such limits are required, and describes the maximum contact periods with a hot surface that any person may be subjected to without being exposed to a risk of burn. Curves of maximum temperatures versus contact times are described for different types of material with different types of surfaces. These temperature limit values shall be taken into consideration by technical committees in determining surface temperature limits in product standards.
