    1. Scope

    1.1 This specification covers special hubless cast iron soil pipe fittings for use in a one-pipe combination vent and waste stack unvented for 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 fittings. These fittings are intended for nonpressure applications, where the selection of the proper size for sanitary, drain, and waste systems allows free air space for gravity drainage.

    Note 1: The fittings covered by this standard are special fittings intended to be used for engineered designed systems and will require special approval by the authority having jurisdiction for use. It is not the intent of this standard to endorse or recommend the use of these fittings for these special applications.

    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 new, special, or transitory, and will be assigned numbers on subsequent prints of this specification.

    1.3 This specification covers fittings of the following patterns and applies to any other patterns that conform with the applicable requirements given in this specification.

    Note 2: The text of this standard references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.

    Note 3: Some sellers of these fittings use the terms “aerator” and “de-aerator” fittings to describe the two types of fittings covered by this standard.

    1.4 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.
