5.1 The techniques described herein are used to produce leak-tight soldered joints between copper and copper alloy tube and fittings, either in shop operations or in the field. Skill and knowledge on the part of the operator or mechanic are required to obtain a satisfactorily soldered joint.1.1 This practice covers a procedure for making capillary joints by soldering of copper and copper alloy tube and fittings.1.2 This procedure is applicable to pressurized systems such as plumbing, heating, air conditioning, refrigeration, mechanical, fire sprinkler, and other similar systems. ASME B31.5 and B31.9 reference the techniques used for satisfactory joint preparation. It is also used in the assembly of nonpressurized systems such as drainage, waste, and vent.1.3 It is not applicable to the assembly of electrical or electronic systems.1.4 Tube and fittings are manufactured within certain tolerances to provide for the small variations in dimensions associated with manufacturing practice. Applicable specifications are listed in Appendix X1.1.5 A variety of solders are available that will produce sound, leak-tight joints. Choice of solder will depend upon the type of application and on local codes. For potable water systems, only lead-free solders shall be used, some of which are described in Specification B32.1.6 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.1.7 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
