2、vision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification establishes the requirements for hard-drawn, seamless capillary tube made from Copper Alloy UNSNos. C1080
3、0, C12000, or C12200.1.2 This tube is commonly supplied in straight lengthsintended for restrictor applications such as metering lines forliquids and gases where close control over smoothness anddiameter of the bore is required to insure uniform flowcharacteristics between tubes.1.3 UnitsThe values
4、stated in inch pound units are to beregarded as standard. The values given in parentheses aremathematical conversions to SI units that are provided forinformation only and are not considered standard.1.4 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 and health practices and determine the applica-bility of regulatory limitations prior to use.2.
