1.1 本规范规定了适用于一般管道、流体输送的类似应用以及通常与焊接、扩口或压缩型配件一起使用的无缝铜管的要求。适用于任何特定应用的铜管类型取决于内部或外部流体压力、安装和使用条件以及当地要求。连接或弯曲方式也是影响所用管类型选择的因素。 2. 注1: 退火管适用于扩口或压缩配件，以及焊接型配件，前提是在需要时对管端进行倒圆和定尺寸。 注2: 拉拔回火管适用于焊接型配件。拉拔状态的K型和L型管适用于某些类型和尺寸的压缩配件。 注3: ASME B16中描述了管道系统中用于焊接或钎焊连接的配件。 18和ASME B16.22。 1.2 除非另有规定，否则管应由以下铜材制成，制造商可选择供应其中任何一种铜材。 铜 UNS编号。 以前使用过 任命 描述 2000年 数据链路协议 磷脱氧， 低残留磷 12200美元 DHP公司 磷脱氧， 高残留磷 1.3 实践中描述了通过焊接组装铜管道或消防喷淋系统 第828页 . 1.4 本规范涵盖了连接铜饮用水或消防喷淋系统的焊料 B32型 规范涵盖了这些系统的可接受焊剂要求 第813页 . 1.5 单位- 以英寸磅单位表示的值应视为标准值。本标准不包括其他计量单位。 1.5.1 本规范是SI规范的配套规范 8800万英镑 ; 因此本说明书中未示出SI等效物。 1.5.1.1 例外情况- 以英寸-磅单位给出的值是标准值，但粒度除外，粒度以国际单位表示。 1.6 以下安全危险警告仅适用于第节的试验方法部分 16 本规范的: 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.7 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 17.1 为了确定是否符合下列特性要求的规定限值 表7 ，观察值或计算值应按照实践中的四舍五入方法进行四舍五 第29页 .

1.1 This specification establishes the requirements for seamless copper water tube suitable for general plumbing, similar applications for the conveyance of fluids, and commonly used with solder, flared, or compression-type fittings. The type of copper water tube suitable for any particular application is determined by the internal or external fluid pressure, by the installation and service conditions, and by local requirements. Means of joining or bending are also factors which affect the selection of the type of tube to be used. 2 Note 1: Annealed tube is suitable for use with flared or compression fittings, and with solder-type fittings, provided rounding and sizing of the tube ends is performed where needed. Note 2: Drawn temper tube is suitable for use with solder-type fittings. Types K and L tube, in the drawn temper, are suitable for use with certain types and sizes of compression fittings. Note 3: Fittings used for soldered or brazed connections in plumbing systems are described in ASME B16.18 and ASME B16.22. 1.2 The tube shall be produced from the following coppers, and the manufacturer has the option to supply any one of them, unless otherwise specified. Copper UNS No. Previously Used Designation Description C12000 DLP Phosphorus deoxidized, low residual phosphorus C12200 DHP Phosphorus deoxidized, high residual phosphorus 1.3 The assembly of copper plumbing or fire sprinkler systems by soldering is described in Practice B828 . 1.4 Solders for joining copper potable water or fire sprinkler systems are covered by Specification B32 . The requirements for acceptable fluxes for these systems are covered by Specification B813 . 1.5 Units— The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard. 1.5.1 This specification is the companion specification to SI Specification B88M ; therefore, no SI equivalents are shown in this specification. 1.5.1.1 Exception— Values given in inch-pound units are the standard except for grain size, which is stated in SI units. 1.6 The following safety hazards caveat pertains only to the test methods portion, Section 16 , 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 17.1 For purposes of determining compliance with the specified limits for requirements of the properties listed in Table 7 , an observed value or calculated value shall be rounded as indicated in accordance with the rounding method of Practice E29 .
