Specifications for Large bed compression machine for plastic pipe.docx

This specifications document outlines the technical requirements for a large bed compression machine that the Illinois Department of Transportation (IDOT) seeks to procure through an Invitation for Bid (IFB) process open to all vendors registered in BidBuy. The machine is intended to replace outdated testing equipment and will be used to test plastic pipe materials for stiffness and flattening characteristics in compliance with AASHTO M252, AASHTO M294, ASTM F949, ASTM D3034, and American Water Works Association standards. The compression testing machine must be capable of constant rate-of-crosshead movement per ASTM D2412 and ASTM D695 test methods, with a compression rate of 0.50±0.02 inches (12.5±0.5 mm) per minute for product stiffness testing and segmented testing capabilities to increase head speed for flattening tests on single specimens.

The machine specifications require capability to test plastic pipe ranging from 4 to 60 inches in diameter, with loading plates of sufficient thickness to prevent bending or deformation and length exceeding specimen length. The equipment must operate on standard 120V or 220V power with a frame capacity of maximum 300 kilonewtons, crosshead speed range of 0.05 to 500 mm/min, minimum crosshead travel of 1,600 millimeters, stroke resolution of 0.001 millimeters, and load measurement accuracy of 0.5 percent of reading down to 1/1000 of load cell capacity. Machine software and computer systems, if required, shall be included as part of the procurement.
