ASTM A888-2018 公共厕所用铸铁粪水管和管件以及暴雨排水管、污水管和通风管设施的规格 Standard Specification for Hubless Cast Iron Soil Pipe and Fittings for Sanitary and Storm Drain,Waste,and Vent Piping Applications

1.1 This specification covers hubless cast iron soil pipe and fittings for use in gravity flow applications. It establishes standards covering material, manufacture, mechanical and chemical properties, dimensions, coating, test methods, inspection, certification, and product marking for hubless cast iron soil pipe and fittings. These pipe and fittings are intended for non-pressure applications, as the selection of the proper size for sanitary drain, waste, vent, and storm drain systems allows free air space for gravity drainage. 1.2 The EDP/ASA numbers indicated in this section represent a Uniform Industry Code adopted by the American Supply Association (ASA). A group designation prefix, 022, is assigned to hubless products, followed by the four-digit identification assigned to individual items and a check digit. This system has been instituted to facilitate EDP control through distribution channels, and is to be used universally in ordering and specifying product items. Those items with no EDP numbers are either new, special, or transitory and will be assigned numbers on subsequent prints of this specification. 1.3 This specification covers pipe and fittings of the following patterns and applies to any other patterns that conform with the applicable requirements given in this specification.2 1.3.1 Lengths:   Figures EDP/ASA Identification Numbers for Hubless Pipe Fig. 1 10 ft (3.0 m) in sizes and 5 ft.
