1. Scope
1.1 This specification covers requirements relating to asbestos-cement nonpressure sewer pipe, joints, and fittings suitable for use with gravity flow, intended for sewerage and drainage applications from point of use to point oftreatment or disposal. It defines certain conditions of manufacture, classification, characteristics, and acceptance tests applicable to these products. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. N OTE 1—Rubber rings suitable for use with this pipe are covered in Specification D1869. N OTE 2—As general guidance to achieve safe and clean construction- site conditions when working with asbestos-cement pipe products, the procedures covered in AWWA No. M-16 shall be followed. N OTE 3—This specification is issued for product standardization and purchasing purposes only, and does not include requirements for instal- lation or the relationships between operating conditions and the strength characteristics of the various classifications of pipe. The purchaser is cautioned that he must correlate installation and operating conditions with the specified characteristics of the pipe. 1.3 Warning—Breathing of asbestos dust is hazardous. Asbestos and asbestos products present demonstrated health risks for users and for those with whom they come into contact. In addition to other precautions, when working with asbestos- cement products minimize the dust that results. For informa- tion on the safe use of chrysoltile asbestos, refer to “Safe Use of Chrysotile: A Manual on Preventive and Control Mea- sures.” 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appro- priate safety, health, and environmental practices and deter- mine the applicability of regulatory limitations prior to use. For a specific safety hazard, see 1.3. 1.5 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
3. Terminology
3.1 Definitions ofTerms Specific to This Standard: 3.1.1 pipe—asbestos-cement nonpressure sewer pipe as de- fined in Sections 1, 3, and 6 of this specification. 3.1.2 coupling—a section for joining asbestos-cement non- pressure sewer pipe, as defined in 6.3, that when properly installed with the proper accessories, develops an assembled joint, equivalent in serviceability and strength to the pipe sections when tested in accordance with 8.3 of this specifica- tion. 3.1.3 fitting—components such as wyes, tees, adaptors, for use in laying asbestos-cement pipe, such that, when properly installed, yields develops an assembly fitting equivalent in serviceability and strength to the pipe sections. 3.2 Lot: 3.2.1 A lot is used herein for designated pipe sizes 150 mm [6 in.] and smaller is defined as those lengths of pipe of that size, class, and type manufactured during the same shift. 3.2.2 A lot, used herein for designated pipe sizes 200 mm [8 in.] through 525 mm [21 in.], is defined as each 300 lengths of pipe or less, of identical size, class, and type manufactured on each maching during a 24-h period. 3.2.3 A lot, used herein for designated pipe sizes larger than 525 mm [21 in.], is defined as each 300 lengths of pipe or less, ofidentical size, class, and type manufactured on each machine during a period of consecutive working days not exceeding 7 days.
