BS EN 1820:2005+A1:2009EN 1820:2005+A1:2009 (E) 5 Introduction This European Standard is one of a series dealing with anaesthetic and respiratory equipment. This document is primarily concerned with the design of the neck, size designation and resi
24、stance to pressure required to distend anaesthetic reservoir bags. The requirement that reservoir bags should be electrically conductive when used with a flammable anaesthetic is widely recognized and is of particular importance when such bags are rhythmically compressed by the anaesthetic provider
25、in order to provide intermittent positive-pressure ventilation. This European Standard gives requirements for both antistatic and non-antistatic bags. Only antistatic bags are suitable for use with flammable anaesthetic agents. This European Standard includes requirements for both single-use and reu
26、sable bags. Reusable bags are intended to comply with the requirements of this document for the recommended product life. The reference test method given as Annex E is not practical for routine use in manufacturing control, because it involves filling the bag with water. For this reason, another tes
27、t method using air rather than water has been provided for information in Annex F. This may ultimately be suitable as the reference test method if it can be shown to give results equivalent to Annex E. A test method for leakage of bags using air rather than water is given as Annex A for information
28、only. Recommendations for materials are given in Annex G. BS EN 1820:2005+A1:2009EN 1820:2005+A1:2009 (E) 6 1 Scope This European Standard specifies requirements for antistatic and non-antistatic reservoir bags for use with anaesthetic apparatus or lung-ventilator breathing systems. It includes requ
29、irements for the design of the neck, size designation, distension and, where relevant, for electrical resistance. This document is not applicable to special-purpose bags, for example bellows and self-expanding bags. Bags for use with anaesthetic gas scavenging systems are not considered to be anaest
30、hetic reservoir bags and are thus outside the scope of this document. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced d
