Standard Specification for Glass-Fiber-Reinforced Polyester Manholes and Wetwells
ABSTRACT
This specification covers glass fiber-reinforced polyester manholes and wetwells for use primarily in sanitary and storm sewer applications. Manhole and wetwell cylinders, manway reducers, and connectors shall be produced from glass fiber-reinforced polyester resin with construction determined by the particular process of manufacture and configuration. The stiffness, soundness, chemical resistance, compressive strength, flexural strength, modulus, and hardness shall be tested to meet the requirements prescribed.
SCOPE
1.1 This specification covers glass fiber-reinforced polyester manholes and wetwells for use primarily in sanitary and storm sewer applications.
1.2 The values given in inch-pound units are to be regarded as the standard. The values in parentheses are provided for information purposes only.
1.3 The following precautionary caveat pertains only to the test methods portion, Section 8, of this specification: 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 appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Note 1—There is no known ISO equivalent to this standard.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
