ISO 13577-3:2016规定了工业热处理设备（TPE）中保护性和反应性大气气体的产生和使用的安全要求。 注:ISO 13577-1中提供了TPE通用的一般安全要求（见引言）。 ISO 13577-3:2016涉及与热化学反应产生的保护性和反应性大气气体的产生和使用有关的重大危害、危险情况和事件，以及它们在第4条和第5条所列的TPE中的使用，当按照制造商预期的条件使用时。 它涵盖 -手动隔离阀下游的管道工程，包括手动隔离阀， -产生大气气体的设备， -TPE中使用大气气体的附加设备， -安全装置，以及 -安全相关控制系统的功能要求 用于产生和使用保护性和反应性大气气体。 它适用于向热塑性弹性体供应大气、源气、惰性气体和工艺液体，并将其从热塑性弹性体中移除，仅限于热塑性弹性体中集成的设备。 ISO 13577-3:2016还详细说明了与大气气体系统及其在热塑性弹性体中的使用相关的预期重大危险，并规定了减少或消除这些危险的适当预防措施。 本标准涵盖的管道和部件的压力危险在附录C中所述的I组最大压力/尺寸关系范围内。 信息技术 -规定了在安装、调试、启动、运行、关闭和维护期间，为确保人员和财产安全而应满足的要求， -当烟气管道系统不被视为TPE的一部分时，不包括其涉及的相关风险， -不适用于TPE主断开装置上游的公用设施供电， -不适用于半导体设备的热塑性弹性体， -不适用于有大气的热塑性弹性体，如过量化学计量燃烧产生的空气和烟气， -不包括TPE的退役， -不包括真空炉， -不处理ISO 13577-1中所述的噪音危害， -不适用于发布日期之前制造的热塑性弹性体和相关装置中大气气体的产生和使用，以及 -给出了使用信息的必要要求。 根据ISO 13577-3:2016设计的热塑性弹性体不会在热塑性弹性体周围区域产生任何潜在爆炸性环境，也不会位于具有潜在爆炸性或危险性环境的区域。 附录B中给出了典型保护性气体和反应性气体的表格。

ISO 13577-3:2016 specifies safety requirements for generation and use of protective and reactive atmosphere gases that are part of industrial thermo-processing equipment (TPE). NOTE The general safety requirements common to TPE are provided in ISO 13577？1 (see Introduction). ISO 13577-3:2016 deals with significant hazards, hazardous situations and events relevant to the generation and use of protective and reactive atmosphere gases created by thermochemical reactions and their use in TPE that are part of TPE as listed in Clause 4 and Clause 5, when used as intended and under the conditions foreseen by the manufacturer. It covers - pipework downstream of and including the manual isolating valve, - equipment for the generation of atmosphere gases, - additional equipment for the use of atmosphere gases in TPE, - safety devices, and - functional requirements for safety related control system for the generation and use of protective and reactive atmosphere gases. It applies to the supply of atmosphere gas, source gas, inert gas and process liquids to TPE and their removal from TPE, confined to equipment integrated in the TPE. ISO 13577-3:2016 also details the anticipated significant hazards associated with atmosphere gas systems and their use in TPE and specifies the appropriate preventative measures for the reduction or elimination of these hazards. The pressure hazard of the piping and components covered by this standard is within the maximum pressure/size relationship of group I as described in Annex C. It - specifies the requirements to be met to ensure the safety of persons and property during installation, commissioning, start up, operation, shutdown and maintenance, - does not cover the relevant risks involved in the flue gas ducting system when it is not considered a part of TPE, - is not applicable to utility supply upstream of the TPE main disconnects, - does not apply to TPE for semi-conductor devices, - does not apply to TPE with atmosphere, such as air and flue gas from an over stoichiometric combustion, - does not cover the decommissioning of the TPE, - does not cover vacuum furnaces, - does not deal with the hazard of noise which is covered in ISO 13577？1, - is not applicable to generation and use of atmosphere gas in TPE and associated plant which is manufactured before the date of its publication, and - gives the necessary requirements for the information for use. A TPE designed according to ISO 13577-3:2016 does not create any potentially explosive atmosphere in the area around the TPE and is not designed to be located in an area with a potentially explosive or hazardous atmosphere. A table of typical protective and reactive gases is given in Annex B.
