ISO 11612:2015规定了由柔性材料制成的防护服的性能要求，这些材料旨在保护穿戴者的身体（手除外）免受热量和/或火焰的影响。为了保护佩戴者的头和脚，ISO 11612:2015范围内的防护服只有绑腿、兜帽和套头衫。然而，关于罩，没有给出对面罩和呼吸设备的要求。 ISO 11612:2015中规定的性能要求适用于可用于多种最终用途的防护服，其中需要具有有限火焰传播特性的防护服，并且用户可能暴露于辐射热、对流热或接触热或熔融金属飞溅。

ISO 11612:2015 specifies performance requirements for protective clothing made from flexible materials, which are designed to protect the wearer's body, except the hands, from heat and/or flame. For protection of the wearer's head and feet, the only items of protective clothing falling within the scope of ISO 11612:2015 are gaiters, hoods, and overboots. However, concerning hoods, requirements for visors and respiratory equipment are not given. The performance requirements set out in ISO 11612:2015 are applicable to protective clothing which could be worn for a wide range of end uses, where there is a need for clothing with limited flame spread properties and where the user can be exposed to radiant or convective or contact heat or to molten metal splashes.
