Additional information

1. Scope

1.1 This specification establishes the requirements for seamless copper tube in coils, suitable for use in refrigeration and air conditioning or other uses, such as oil lines and gasoline lines.

1.2 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.

1.3 The tube shall be produced of the following coppers. Unless otherwise specified, tubes made from any one of these coppers may be supplied:

Copper Alloy UNS No.	Previously Used Designation	Type of Copper

C10200	OF	Oxygen-free without residual deoxidants^A
C10300	...	Oxygen-free, extra low phosphorus^A
C10800	...	Oxygen-free, low phosphorus^A
C12000	DLP	Phosphorized, low residual phosphorus
C12200	DHP	Phosphorized, high residual phosphorus

^A See Classification B224.

1.4 The following safety hazards caveat pertains to the test method portion, Section 17, of this specification. 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 appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
