2、inal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers special hubless cast iron soilpipe fi
3、ttings for use in a one-pipe combination vent and wastestack unvented for gravity flow applications. It establishesstandards covering material, manufacture, mechanical andchemical properties, dimensions, coating, test methods,inspection, certification, and product marking for hubless castiron soil p
4、ipe fittings. These fittings are intended for nonpres-sure applications, where the selection of the proper size forsanitary, drain, and waste systems allows free air space forgravity drainage.NOTE 1The fittings covered by this standard are special fittingsintended to be used for engineered designed
5、systems and will requirespecial approval by the authority having jurisdiction for use. It is not theintent of this standard to endorse or recommend the use of these fittings forthese special applications.1.2 The EDP/ASA numbers indicated in this section repre-sent a uniform industry code adopted by
6、the American SupplyAssociation (ASA). A group designation prefix, 022, is as-signed to hubless products, followed by the four-digit identi-fication assigned to individual items and a check digit. Thissystem has been instituted to facilitate EDP control throughdistribution channels, and is to be used
7、 universally in orderingand specifying product items. Those items with no EDPnumbers are new, special, or transitory, and will be assignednumbers on subsequent prints of this specification.1.3 This specification covers fittings of the following pat-terns and applies to any other patterns that confor
8、m with theapplicable requirements given in this specification.NOTE 2The text of this standard references notes and footnotes thatprovide explanatory material. These notes and footnotes (excluding thosein tables and figures) shall not be considered as requirements of thestandard.NOTE 3Some sellers of
9、 these fittings use the terms “aerator” and“de-aerator” fittings to describe the two types of fittings covered by thisstandard.1.4 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for the

20、efects that wouldmake the castings unfit for the use for which they are intended.4.3 To minimize the possibility of introducing radioactivematerial to a melting operation, ferrous scrap, pig iron, and anyrecycled ferrous material shall be screened by the manufacturerfor radioactivity with suitable d
21、etection devices operated inaccordance with the detection manufacturers instructions.Written operating, calibration, and maintenance procedures forthe detection equipment shall be provided to the purchaser forreview when requested. Records shall be maintained by load ofthese tests for a period of se
22、ven years.4.3.1 Only radiation detection devices designed specificallyfor the purpose of screening ferrous material shipments shall beused for the purpose of conforming to this requirement.Handheld detection devices (Geiger counters) are not appro-priate and shall not be used for the purpose of conf
