19、on of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee
20、. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and tho
21、se intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (
22、see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the doc
23、ument will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.For an explanation on the meaning of ISO specific terms and
24、 expressions related to conformity assessment, as well as information about ISOs adherence to the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following URL: www.iso.org/iso/foreword.html.The committee responsible for this document is ISO/TC 244, Industr

26、eactive atmosphere gases Part 4: Protective systems ISO 2016 All rights reserved vBS ISO 13577-3:2016ISO 13577-3:2016(E)IntroductionThis part of ISO 13577 is a Type C-Standard as defined in ISO 12100.The machinery concerned and the extent, to which hazards, hazardous situations and events are covere
27、d, is indicated in the scope of this part of ISO 13577.When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed a
28、nd built according to the provisions of this type C standard.Compliance with product standards, e.g. ISO 22967 or ISO 22968 is not sufficient to ensure the minimum safety requirement for TPE. This part of ISO 13577 shall always have priority for TPE.Industrial furnaces and associated thermo-processi
29、ng equipment (TPE) generally consists of the following components: processing chamber (e.g. steel construction with lining and/or refractory); heating systems; protective system; control and instrumentation system/operator-control level.ISO 13577-1 provides the general safety requirements common to
30、TPE. This part of ISO 13577 details in addition specific safety requirements for generation and use of protective and reactive atmosphere gases that are part of TPE as listed in the scope. These requirements establish the minimum acceptable requirements for safety functions required for various proc
31、esses. Where a process is not part of the TPE, the requirements do not apply.For example, the minimum requirements for the opening and closing of doors on a TPE does not apply to TPE that do not have doors in their design.NOTE As stated in its scope, ISO 13577-1 does not cover blast furnaces, conver
32、ters (in steel plants), boilers and equipment not covered under ISO 12100.The requirements of protective system are specified in ISO 13577-4.If a general provision of ISO 13577-1 counters provisions in this part of ISO 13577, the provisions of this part of ISO 13577 take precedence.It is assumed tha
33、t TPE will only be operated and maintained by trained personnel.vi ISO 2016 All rights reservedBS ISO 13577-3:2016Industrial furnaces and associated processing equipment Safety Part 3: Generation and use of protective and reactive atmosphere gases1 ScopeThis part of ISO 13577 specifies safety requir
34、ements 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).This part of ISO 13577 deals with significant hazards, hazardous s
35、ituations 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.This part
36、of ISO 13577 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 systemfor the generation and use
37、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.This part of ISO 13577 also details the anticipated significant hazards associated with atm
38、osphere 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
39、.This part of ISO 13577 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 T
