1、Designation:D841921Standard Specification forAnesthesia Reservoir Bags1This standard is issued under the fixed designation D8419;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indica
2、tes the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This specification covers anesthesia reservoir bags foruse with anesthesia breathing systems.For purposes of thisspecification,the reservoir bag includes the neck,body
3、,andneck bushing,if provided.Special-purpose bags,for example,bellows,evacuation,and self-expanding bags are excludedfrom the scope of this specification.1.2 Thefollowingsubjectsarecovered:material,construction,neck,size,compliance(pressure-volumerelationship),electrical conductivity,marking and lab
4、eling,andtest methods to substantiate compliance with the requirements.Alternative test methods may be employed provided they canbe shown to be equivalent or better.(A rationale is given inAppendix X1.)1.3 This standard does not purport to address all of thesafety concerns,if any,associated with its
5、 use.It is theresponsibility of the user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accor-dance with internationally recognized principle
