The content of this Standard Practice is the result of the efforts of competent and concerned volunteers to provide an effective, clear, and non-exclusive specification that will benefit the industry as a
4、 whole. This MSS Standard Practice is intended as a basis for common practice by the manufacturer, the user, and the general public. The existence of an MSS Standard Practice does not in itself preclude the manufac- ture, sale, or use of products not conforming to the Standard Practice. Mandatory co

Non-toleranced dimensions in this Standard Practice are nominal, and unless otherwise specified, shall be considered “for reference only”. This document has been substantially revised f

10、Society was requested to develop a Standard Practice for line valves and assigned this as a project to the MSS Committee 1 12, Water Works Valves and Fittings. Many ofthe significant components of service lines for drinking water systems have not been specifically covered by standards. The MSS Commi
11、ttee 1 12, Water Works Valves and Fittings Committee, decided to fill this need in the water works industry by creating this Standard Practice (SP), which has a broader scope than previous drinking water service line standards. However, the tubing, pipe, water main, water meter, and machines associa
12、ted with drinking water service lines are not covered by this SP. Field testing information is provided in Section 6.4 but is not a part of this Standard Practice. The Annex at the back of this Standard Practice is an official part of this Standard Practice. 11 Copyright MSS Provided by IHS under li

19、 without license from IHS -,-,- MSS STANDARD PRACTICE SP-116 SERVICE-LINE VALVES AND FITTINGS FOR DRINKING WATER SYSTEMS O. PURPOSE To provide a Standard Practice covering most of the significant valves and fittings used in drinking water service-line systems including both buried and non- buried va
20、lves, fittings, meter settings, and service saddle clamps. 1. SCOPE 1.1 This standard covers valves and fittings in sizes 1/2” through 2” NPS for use in drinking water sys- tem service-line between the main and the meter. Included are: a) Buried valves and fittings that are designed to be in direct
21、contact with the soil (corporation valves, service saddle clamps, and curb valves). b) Non-buried valves and fittings that are not de- signed to be in direct contact with the soil (meter valves, check valves, meter fittings, and meter settings). c) Fittings include various types of couplings and ada
22、pters. Not included is: d) Reduced pressure backflow preventers. 1.2 This Standard Practice establishes the minimum requirements that a drinking water service-line valve or fitting must possess at the time of manufacture. Details of design and manufacture, other than those stated in this standard, i
23、ncluding such design and pro- duction tests to ensure that each valve or fitting will have these capabilities, remain the responsibility of the manufacturer. 2. DEFINITIONS 2.1 Under this Standard Practice the following defi- nitionsshall apply. Other definitions may be found in MSS SP-96. 2.1.1 Ang
24、le Design Meter Valve A meter valve in which the two body ends and the inlet and outlet flow ways are at right angles (Le., 90) to each other. 2.1.2 Adapter Facilitates the connection of an item to a size or type of tubing, pipe, or fitting, which is different from that to which the item was designe
