前言这是ASME A112的第二版。18.6/CSA B125。6、柔性水接头。它取代了2009年出版的前一版。本版本中出现了以下变化:a）更新了NSF 61最新版本的参考；b） 修改工作温度；c） 新的低铅要求；d） 更新了填充阀螺纹要求；e）更新制冰机压降要求。范围1。1.本标准涵盖了在a）可接近位置的持续压力下用于供水系统的柔性水连接器；和b）仅限休闲车的间歇性压力。1.2在本标准中，“应”用于表示要求，即用户为遵守本标准而有义务满足的规定；“应该”用于表示建议或建议但不需要的建议；“可”用于表示一个选项或在标准范围内允许的选项。注释随附条款不包括要求或替代要求； 随附条款的注释的目的是将解释性或信息性材料与文本分开。表和图的注释被视为表或图的一部分，可以作为要求编写。附件被指定为规范性（强制性）或信息性（非强制性）以定义其应用。1.3国际单位制是加拿大的记录单位。在本标准中，码/磅单位显示在括号中。每个测量系统中规定的值在应用中是等效的；然而，每个系统都要独立使用。合并两个测量系统的值可能会导致不符合本标准。所有对加仑的引用均指美国加仑。有关本标准中使用的转换标准的信息，请参见附录B。

PrefaceThis is the second edition of ASME A112.18.6/CSA B125.6, Flexible water connectors. It supersedes the previous edition published in 2009. The following changes appear in this edition: a) updated reference to the latest edition of NSF 61; b) revised working temperatures; c) new low lead requirements; d) updated fill valve thread requirements; and e) updated ice maker pressure drop requirements.Scope1.1 This Standard covers flexible water connectors for use in water supply systems under a) continuous pressure in accessible locations; and b) intermittent pressure in recreational vehicles only. 1.2 In this Standard, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the Standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application. 1.3 SI units are the units of record in Canada. In this Standard, the yard/pound units are shown in parentheses. The values stated in each measurement system are equivalent in application; however, each system is to be used independently. Combining values from the two measurement systems can result in non-conformance with this Standard. All references to gallons are to U.S. gallons. For information on the conversion criteria used in this Standard, see Annex B.
