30、g system where the operator makes connections and disconnections for the disposal of medical gases and anaesthetic vapours from anaesthetic machines or other items of medical equipment, and where a wrong connection may create a hazard to the patient. It is important that terminal units and their com
31、ponents be designed, manufactured, installed and maintained in such a way as to meet the basic requirements specified in this part of ISO 9170. This part of ISO 9170 pays particular attention to: suitability of materials; type specificity; dimensions of probes and type-specific connection points; cl
32、eanliness; testing; identification; information supplied. This part of ISO 9170 specifies the provision of information for the installation and subsequent testing of terminal units. Testing of terminal units prior to use is critical to patient safety and it is essential that terminal units are not u
33、sed until full testing in accordance with ISO 7396-2 has been completed. Annex A contains rationale statements for some of the requirements of this part of ISO 9170. The clauses and subclauses marked with an asterisk (*) after their number have corresponding rationale contained in Annex A, included
34、to provide additional insight into the reasoning that led to the requirements and recommendations that have been incorporated in this part of ISO 9170. It is considered that knowledge of the reasons for the requirements will not only facilitate the proper application of this part of ISO 9170, but wi
35、ll expedite any subsequent revisions. 4 DIN EN ISO 9170-2:2009-09 EN ISO 9170-2:2008 (E) 1 Scope 1.1 This part of ISO 9170 specifies the requirements and dimensions for terminal units intended for use in anaesthetic gas scavenging disposal systems in accordance with ISO 7396-2. 1.2 This part of ISO
36、9170 specifies two types of terminal unit according to whether the power device is upstream or downstream of the terminal unit. 1.3 This part of ISO 9170 also specifies requirements and dimensions for the mating counterpart (probe) of the type-specific connection point which is part of the terminal
37、unit. 1.4 This part of ISO 9170 does not specify the ranges of nominal operating pressure for terminal units, which are defined in ISO 7396-2. 1.5 This part of ISO 9170 does not specify requirements for terminal units for use with compressed medical gases and vacuum, which are covered in ISO 9170-1.
