As a piano performance major in another life, I’m always interested in standards with unusual ties to music in some way. So imagine my surprise to learn that one of our most popular ASTM metal standards is the ASTM A228/A228M, “Standard Specification for Steel Wire, Music Spring Quality.” This specification for high quality round cold-drawn steel is a mainstay of industry! And the new 2014 Edition has just been released.
The steel wire specified by the ASTM A228/A228M is uniform in mechanical properties, which makes it ideal for the manufacture of all types of springs that may have to endure high stresses or have good fatigue properties. The 5 page standard has not been updated since 2007, so you’ll want to review this new edition if you use the document.
Your document will provide you with requirements for ordering information, for materials and manufacture, and for the chemical composition. There are specific tests to insure the product has the needed mechanical properties. And the metallurgical requirements are also spelled out.
With regards to workmanship, this specification provides information on dimensions and permissible variations, on finish and appearance, inspection, rejection, and certification.
The ASTM A228/A228M finishes up with a section on packaging, marking and loading for shipment, as well as a short keyword section. So the specification provides both purchaser and manufacturer with the needed range of information required for procurement transactions.
