Customer Acceptance Standard 1200 mm and 1000 mm Fiberglass Manhole w/600 mm Manway
General
Amiantit Fiberglass Manholes are flexible composites constructed of a thermo setting chemical resistant polyester resin, glass fiber reinforcement with silica sand and additives as required The manhole is a 1200 mm or 1000 mm cylinder with a hemispheric ally shaped concentric reducer (termed the cone' ) at the top to form the narrower 600 mm manway The cone and cyclindrical portion are manufactured separately and are factory joined with a contact molded Fiberglass joint to produce a one piece manhole Fiberglass manholes conform to the ASTM Specification for Glass Fiber Reinforced Polyester Manhole specification D 3753 79.

The ring and cover must rest on a course of bricks or a concrete ring, not the fiberglass support ledge All surcharge load must be applied to the ring and cover. Holes or arches may be cut in the cylindrical portion of the manhole using a circular saw, sabre saw or similar equipment with a masonry type blade. Axes, hammers, chisels or similar tools must not be used to make cuts in the manhole.
Maximum single cutout hole diameter is 750 mm for the 1200 mm manhole and 600 mm for the 1000 mm manhole. Sum of all cutouts cannot exceed 1900 mm for the 1200 mm manhole and 1500 mm for the 1000 mm manhole.
