22、n) is a worldwide federation 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 rep
23、resented on that committee. 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. International Standards a
24、re drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an Internatio
25、nal Standard requires approval by at least 75 % of the member bodies casting a vote. 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. ISO 7396-2 was p
26、repared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 215, Respiratory and anaesthetic equipment, in collaboration with Technical Committee ISO/TC 121, Anaesthetic and respiratory equipment, Subcommittee SC 6, Medical gas systems, in accordance with the Agreement on
27、technical cooperation between ISO and CEN (Vienna Agreement). This second edition cancels and replaces the first edition (ISO 7396-2:2000), which has been technically revised. ISO 7396 consists of the following parts, under the general title Medical gas pipeline systems: Part 1: Pipeline systems for
28、 compressed medical gases and vacuum Part 2: Anaesthetic gas scavenging disposal systems EN ISO 7396-2:2007vIntroduction Anaesthetic gas scavenging systems (AGSS) are used to reduce occupational exposure to anaesthetic gases and vapours. The anaesthetic gas scavenging system comprises three main par
29、ts: a transfer system, a receiving system, and a disposal system. A schematic diagram of typical anaesthetic gas scavenging systems is shown in Figure 1. Requirements for receiving systems and transfer systems are specified in ISO 8835-3. Type-specific connections for terminal units are specified in
30、 ISO 9170-2. In this part of ISO 7396, specifications and test procedures are given to ensure compatibility between the components of the system. This part of ISO 7396 specifies requirements for pipelines for anaesthetic gas scavenging systems for anaesthetic gases and vapours. It is intended for us
31、e by those persons involved in the design, construction, inspection and operation of healthcare facilities treating human beings. It is advisable that those persons involved in the design, manufacture and testing of equipment intended to be connected to pipeline systems also be aware of the contents
32、 of this part of ISO 7396. Specific components are used for scavenging terminal units and for other connectors which are intended to be used by the operator. In addition, the system is tested and certified to operate at safe flows and without leakage. It is also intended to address issues of patient
33、 safety. The objectives of this part of ISO 7396 are to ensure the following: a) avoidance of cross connections between different pipeline systems; b) continuity of function of the system; c) use of suitable materials; d) cleanliness of components; e) correct installation; f) provision of indicating
34、 system(s); g) correct marking of the pipeline system and components; h) testing, commissioning and certification; i) correct operational management. Annex E contains rationale statements for some of the requirements of this part of ISO 7396. It is included to provide additional insight into the rea
35、soning that led to the requirements and recommendations that have been incorporated in this part of ISO 7396. The clauses and subclauses marked with (*) after their number have corresponding rationale contained in Annex E. EN ISO 7396-2:2007blank1Medical gas pipeline systems Part 2: Anaesthetic gas
36、scavenging disposal systems 1 Scope This part of ISO 7396 specifies requirements for the design, installation, function, performance, documentation, testing and commissioning of anaesthetic gas scavenging disposal systems to ensure patient safety and to minimize exposure of the operator and other pe
37、rsons to anaesthetic gases and vapours. It includes requirements for the power device, pipeline system, performance, non-interchangeability between key components and avoidance of cross connections between anaesthetic gas scavenging (AGS) disposal systems and medical gas and vacuum pipeline systems.
38、 NOTE In this part of ISO 7396, the term “pipeline” refers exclusively to pipelines that are part of a dedicated anaesthetic gas scavenging system (AGSS). This part of ISO 7396 is applicable only to those disposal systems intended to be connected via AGSS terminal units conforming to ISO 9170-2 and
39、to AGSS receiving systems conforming to ISO 8835-3. This part of ISO 7396 also applies to: extensions of existing AGSS disposal systems; modifications of existing AGSS disposal systems; modifications or replacement of power devices. 2 Normative references The following referenced documents are indis
