Scope*1.1 This specification establishes the requi
3、rements for hard-drawn, seamless capillary tube made from Copper Alloy UNSNos. C10800, 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
4、is required to insure uniform flowcharacteristics between tubes.1.3 The values stated in inch pound units are to be regardedas the standard. The values given in parentheses are mathemati-cal conversions to SI units, which are provided for informationonly and are not considered standard.1.4 The follo
5、wing safety hazard caveat pertains only to thetest method described in section 16.4 (Cleanness Test) of thisspecification: This standard does not purport to address all ofthe safety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-pri
6、ate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.
