About this file
This is a specifications document for the Illinois Department of Transportation (IDOT) Materials CVN Tester procurement, outlining the technical requirements for a British Pendulum Charpy V-Notch impact tester. The equipment will replace an outdated Charpy V-Notch (CVN) tester in the metals laboratory before the department's relocation to a new building. The machine will be used to test products including ASTM F1554 anchor bolts and ASTM A500 bridge rail materials. The specifications require the tester to meet all general requirements of ASTM E23 standards and include essential components such as a Charpy centering gauge, tongs, impact striker, anvil inserts, and shrouds.
The equipment must have a rated potential energy minimum of 325 Joules with an impact velocity between 3 and 6 m/s, and shall incorporate a digital display capable of readings in increments of 0.25% of range capacity or less with supporting applicable software and computer systems. The machine frame and base must meet ASTM E23 and ISO recommendations, with total frictional loss not exceeding 0.75% of range capacity. The tester must support both full-size and sub-size Charpy specimen testing with capability for non-ambient specimen testing. Safety requirements include an integrated guard and safety control system meeting ISO 148 standards, motorized hammer lift with automatic return to start position, hammer brake and clutch mechanisms, and a safety enclosure preventing hammer release when doors are open.
