Designation: B360 −20
Standard Speciﬁcation for
Hard-Drawn Copper Capillary Tube for Restrictor
Applications
1
This standard is issued under the ﬁxed designation B360; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript 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 UNS
Nos. C10800, C12000, or C12200.
1.2 This tube is commonly supplied in straight lengths
intended for restrictor applications such as metering lines for
liquids and gases where close control over smoothness and
diameter of the bore is required to insure uniform ﬂow
characteristics between tubes.
1.3 Units—The values stated in inch pound units are to be
regarded as standard. The values given in parentheses are
mathematical conversions to SI units that are provided for
information only and are not considered standard.
1.4 This standard does not purport to address all of the
safety concerns, if any, associated with its use. It is the
responsibility 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.
1.5 This international standard was developed in accor-
dance with internationally recognized principles on standard-
ization established in the Decision on Principles for the
Development of International Standards, Guides and Recom-
mendations issued by the World Trade Organization Technical
Barriers to Trade (TBT) Committee.

5.1.3 Dimensions: inside and outside diameter (Table 2);
5.1.4 Air Flow requirements (ft
3
/min or cfm), (see 10.3), if
required;
NOTE 1—Product is speciﬁed to air ﬂow requirements for capillary
applications.
5.1.5 Quantity—total length, number of pieces or total
weight of each size; and
5.1.6 Length per piece of each size.

pieces selected in 13.1.2.
14.1.3 Specimens for all other tests must conform to speci-
ﬁcation requirements.
14.2 Retests:
14.2.1 When requested by the manufacturer or supplier, a
retest shall be permitted when results of tests obtained by the
purchaser fail to conform to the requirements of the product
speciﬁcation.
