22、iography . 45 EN ISO 7396-2:2007iv Foreword ISO (the International Organization for Standardization) 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 in
23、terested in a subject for which a technical committee has been established has the right to be represented 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 Electrotechni
24、cal Commission (IEC) on all matters of electrotechnical standardization. International Standards are 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
25、 technical committees are circulated to the member bodies for voting. Publication as an International 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.
26、 ISO shall not be held responsible for identifying any or all such patent rights. ISO 7396-2 was prepared 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 r
27、espiratory equipment, Subcommittee SC 6, Medical gas systems, in accordance with the Agreement on 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 f
28、ollowing parts, under the general title Medical gas pipeline systems: Part 1: Pipeline systems for 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 exposur
29、e to anaesthetic gases and vapours. The anaesthetic gas scavenging system comprises three main parts: 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
30、systems are specified in ISO 8835-3. Type-specific connections for terminal units are specified in 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 pipelin
31、es for anaesthetic gas scavenging systems for anaesthetic gases and vapours. It is intended for use 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 a
32、nd testing of equipment intended to be connected to pipeline systems also be aware of the contents 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 certif
33、ied to operate at safe flows and without leakage. It is also intended to address issues of patient 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 sui
34、table materials; d) cleanliness of components; e) correct installation; f) provision of indicating 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 th
35、e requirements of this part of ISO 7396. It is included to provide additional insight into the reasoning 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 c
36、ontained in Annex E. EN ISO 7396-2:2007blank1Medical gas pipeline systems Part 2: Anaesthetic gas 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 scavengi
37、ng disposal systems to ensure patient safety and to minimize exposure of the operator and other persons 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 betw
38、een anaesthetic gas scavenging (AGS) disposal systems and medical gas and vacuum pipeline systems. 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 tho
39、se disposal systems intended to be connected via AGSS terminal units conforming to ISO 9170-2 and 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
40、 replacement of power devices. 2 Normative references The following referenced documents are indispensable for the application of this document.
