Abstract:

This specification covers asbestos-cement perforated and plain pipe intended for use in the conveyance of drainage water for the subsurface drainage of highways, airports, farms, foundations, and other similar drainage work. Asbestos-cement underdrain pipe shall be composed of an intimate mixture of portland cement or portland blastfurnace slag cement or portland blast-furnace slag or pozzolan cements and asbestos fiber with or without fine silica or additives containing such silica that is capable of reacting completely to yield calcium silicate reaction products upon autoclaving. The mixture shall not contain more than 0.2 % of nondeleterious organic matter. The material shall be of laminar construction, formed under pressure to a homogeneous structure, and cured to meet the physical and chemical requirements specified. Crushing tests shall be conducted in order to determine the crushing strength of the pipes.

Scope:

1.1 This specification covers asbestos-cement perforated and plain pipe intended for use in the conveyance of drainage water for the subsurface drainage of highways, airports, farms, foundations, and other similar drainage work.

1.2 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.

1.3 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.
