2、n. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers polymer concrete pipe, 6 in.(150 mm) through 144 in. (3 660 mm), intended for use ingravity-flow system
3、s for conveying sanitary sewage, stormwater, and industrial wastes.NOTE 1There is no similar or equivalent ISO standard.1.2 Although this specification is suited primarily for pipe tobe installed by direct burial and pipe jacking, it may be used tothe extent applicable for other installations such a
4、s slipliningand rehabilitation of existing pipelines.NOTE 2Unlike reinforced thermosetting resin pipes, polymer con-crete pipe is designed and installed using rigid pipe design theory andpractices.1.3 The values stated in inch-pound units are to be regardedas the standard. The values given in parent
5、heses are forinformation only.1.4 The following safety hazards caveat pertains only to thetest methods portion, Section 8, of this specification. Thisstandard may involve hazardous materials, operations, andequipment. This standard does not purport to address all of thesafety concerns, if any, assoc
6、iated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory requirements prior to use.2.
