ASTM C1821/C1821M-16 - 15.2.2016
 
Significance and Use

4.1 This practice is useful as a reference by an owner and/or the engineer in preparing project specifications.

4.2 The practice is useful as a reference by an owner, engineer, or installing contractor to properly install precast concrete circular manholes.

 
1. Scope

1.1 This practice covers the procedures to be followed in the planning, site preparation, installation, testing and backfilling of underground vertical reinforced circular precast concrete manholes and components manufactured in accordance with Specification C478 (C478M) and used in sewer, drainage, and water works.

1.2 Concrete pipe and box culverts are not covered under this practice. Also, precast concrete utility structures covered in Specification C858 are excluded from this practice.

1.3 Units—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.

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 appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
