1、Designation:F 1205 88(Reapproved 1999)Standard Specification forAnesthesia Breathing Tubes1This standard is issued under the fixed designation F 1205;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number
2、in parentheses indicates the year of last reapproval.Asuperscript epsilon(e)indicates an editorial change since the last revision or reapproval.1.Scope1.1 This specification covers anesthesia breathing tubes,integrally attached end fittings,and integrally attached compo-nents for use with anesthesia
3、 breathing systems.Excluded aresimilar tubes for specific other purposes,such as those usedwith some breathing machines,pediatric anesthesia circuits,and gas scavenging tubes.1.2 The following subjects are covered:terminology,di-mensions,labeling and marking,selected performance require-ments,and te
4、st methods to substantiate compliance with therequirements.Alternative test methods may be employedprovided that they can be shown to be equivalent or better.NOTE1This specification supersedes ANSI Standard Z 79.6-1975.1.3 This standard does not purport to address all of thesafety problems,if any,as
5、sociated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:F 1054 Specification For Conical Fittings Of 15 mm and 22m
