Title
Standard Practice for Rehabilitation of a Sewer Service Lateral and Its Connection to the Main Using a One Piece Main and Lateral Cured-in- Place Liner
ASTM International
Publication Date:
Jun 1, 2006
Scope:
This practice covers requirements and test methods for the reconstruction of a sewer service lateral pipe having an inner diameter of 3 to 12 in. and its connection to the main pipe having an inner diameter of 6 to 24 in. without excavation. The lateral pipe is accessed remotely from the main pipe and from a lateral cleanout. This will be accomplished by the installation of a resin impregnated one-piece main and lateral cured in-place lining (MLCIPL) by means of air or water inflation and inversion. The MLCIPL is pressed against the host pipe by pressurizing a bladder and is held in place until the thermoset resins have cured. When cured, the MLCIPL shall be a continuous, one piece, tight fitting, corrosion resistant lining extending over a predetermined length of the lateral pipe and the adjacent section of the main pipe providing a verifiable non-leaking structural connection and seal.
The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information only.
There is no similar or equivalent ISO Standard.
