Standard Specification for Asbestos-Cement Nonpressure Sewer Pipe
 N C428/C428M

Annotation

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 of treatment or disposal. It defines certain conditions of manufacture, classification, characteristics, and acceptance tests applicable to these products.

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.

NOTE 1—Rubber rings suitable for use with this pipe are covered in Specification D1869.

NOTE 2—As general guidance to achieve safe and clean constructionsite conditions when working with asbestos-cement pipe products, the procedures covered in AWWA No. M-16 shall be followed.

NOTE 3—This specification is issued for product standardization and purchasing purposes only, and does not include requirements for installation 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.

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 asbestoscement products minimize the dust that results. For information on the safe use of chrysoltile asbestos, refer to "Safe Use of Chrysotile: A Manual on Preventive and Control Measures." 2
