It was prepared by Subcommittee CH/121/6, Medical gas supply systems, under the authority of Technical Committee
6、 CH/121, Anaesthetic and respiratory equipment. A list of organizations represented on these committees can be obtained on request to their secretary.Relationship with other publicationsTerminal units for anaesthetic gas scavenging systems are specified in BS EN ISO 9170-2, which was written with th
7、e intention that national standards would be in place to specify the dimensions of the terminal units for high flow gas scavenging systems. Such high flow systems are standard in the UK and the dimensions were previously given in BS 6834 which was withdrawn on publication of BS EN 737-4:1998, and wh
8、ich in turn has been superseded by BS EN ISO 9170-2. This British Standard has been prepared to specify the dimensions of the probes and type-specific connection points for terminal units for these systems.Presentational conventionsThe provisions of this standard are presented in roman (i.e. upright
9、) type. Its requirements are expressed in sentences in which the principal auxiliary verb is “shall”.Commentary, explanation and general informative material is presented in smaller italic type, and does not constitute a normative element.Contractual and legal considerationsThis publication does not
10、 purport to include all the necessary provisions of a contract. Users are responsible for its correct application.Compliance with a British Standard cannot confer immunity from legal obligations.
