The ASTM F2482 standard promotes safety by its sheer accuracy at measuring tension from within the critical joint. “It is for applications where reliability, safety, and certifiable product performance are critically important.” “If the customer is serious about controlled bolting for their critical joints, it will be important to them that the fasteners they use achieve the +/-5% accuracy standard,” said Brooks. In addition, the standard provides control of other essential areas such as material, manufacturing process, testing and calibration, inspection and certification.”
“We believe there are distinct advantages to being compliant. “These are critical measures of accuracy and precision,” said Brooks. Valley Forge director of engineering James Brooks says meeting the ASTM F2482 Standard has benefits for both the manufacturer and the customer. After two years, peer collaboration, and several ballots, the standard was accepted.Ĭurrently, 17 years after the acceptance of the ASTM F2482 Standard, Valley Forge products are still the only ones that comply with the specification that fasteners accurately measure tension as a percentage of load to within +/-5%. In 2002, Valley Forge & Bolt, maker of patented bolting products, recognized the importance of having a consensus standard detailing the requirements for load indicating fasteners and approached a subcommittee of the F16 Committee on Fasteners.
Its process for creating new standards requires collaboration among industry participants to develop and finalize language and standards, then a wider vote to accept it. It has been around for more than a century and is well known and highly respected in many industries. ASTM’s abstract describes this specification as covering “externally threaded … fasteners, capable of indicating clamping forces up to yield strength during the tightening process or post installation residual tension, or both.” In other words, fasteners that indicate tension.ĪSTM is the largest organization in the world for developing and publishing voluntary, full-consensus Here, we’ll be taking closer look at ASTM, specifically the ASTM F2482 Standard.
Whether it’s ISO (the International Organization for Standardization), DIN (Deutsches Institut für Normung), ASME (American Society of Mechanical Engineers), ANSI (American National Standards Institute), or ASTM (American Society for Testing Materials), each serves a specific purpose. Industry is ruled by standards, overseen by a number of national and international standardizing bodies. Why ASTM-Complying Fasteners Are Important For Critical Joints
