The use of material other than HDPE pipe may be required by ASPA if it is determined that HDPE pipe is unsuitable for the particular application. All material used in the production of water main piping shall be approved by the National Sanitation Foundation (NSF). 1.4 DOCUMENTATION 1.4.1 Documentation from the resin's manufacturer showing results of the following tests for resin identification: 1.4.1.1 Melt Flow Index ASTM D1238 ASG Housing Distribution Lines Replacement Project 2 1.4.1.2 Density ASTM D1505 1.5 MANUFACTURER 1.5.1 All HDPE pipe and fittings shall be from a single manufacturer, who is fully experienced, reputable and qualified in the manufacture of the HDPE pipe to be furnished. The pipe shall be designed, constructed and installed in accordance with the best practices and methods and shall comply with these Specifications. Qualified manufacturers shall be: PLEXCO Division of Chevron Chemical Company, DRISCOPIPE as manufactured by Phillips Products Co., Inc., SCLAIRPIPE as manufactured by DuPont of Canada or equal as approved by the Utilities Engineer. 1.6 FINISHED PRODUCT EVALUATION 1.6.1 Production staff shall check each length of pipe produced for the items listed below. The results of all measurements shall be recorded on production sheets, which become part of the manufacturer's permanent records. 1.6.1.1 Pipe in process shall be checked visually, inside and out for cosmetic defects (grooves, pits, hollows, etc.) 1.6.1.2 Pipe outside diameter shall be measured using a suitable periphery tape to ensure conformance with ASTM F714 or ASTM D3035, whichever is applicable. 1.6.1.3 Pipe wall thickness shall be measured at 12 equally spaced locations around the circumference at both ends of the pipe to ensure conformance with ASTM F714 or ASTM D3035, whichever is applicable. 1.6.1.4 Pipe length shall be measured. 1.6.1.5 Pipe marking shall be examined and checked for accuracy. 1.6.1.6 Pipe ends shall be checked to ensure they are cut square and clean. 1.6.1.7 Subject inside surface to a "reverse bend test" to ensure the pipe is free of oxidation (brittleness). 1.7 STRESS REGRESSION TESTING 1.7.1 The polyethylene pipe manufacturer shall provide certification that stress regression testing has been performed on the specific polyethylene resin being utilized in the manufacture of this product. This stress regres
