Group 2 June 1. Pipe connected by bell and spigot joints may not be perforated in the area of the bells and aashtoo. Customary units are shown in parentheses, and may not be exact equivalents. Samples of materials and pipe may be taken by the specifying agency. Inspect for damage while at the specified deflection and after load removal. Load the connected pipe and joint between parallel plates at the rate of Type of pipe Section 4.
The dry-blended sample shall be fully homogenized by melt blending via a twin screw lab extruder or other melt homogenization technique that has been verified to provide similar levels of homogenization prior to testing for physical properties. This specification does not include requirements for bedding, backfill, or earth cover load. The specifying agency may require an annual third-party independent assurance test.
Group 2 June A greater number of rows for increased inlet area shall be subject to agreement between purchaser and manufacturer.
