This reference file allows technicians and quality control professionals to confirm that a hardness tester is reading accurately before running production tests. At 45 RC, it sits in the mid-range of the Rockwell C scale, making it a practical verification standard for a wide range of metalworking and inspection applications. The file weighs 0.05 pounds, making it easy to store and handle at a test bench.\u003c\/p\u003e\n\u003cp\u003eThis testing file is designed for use with most bench-type Rockwell and Rockwell Superficial type hardness testers. It is commonly used in machine shops, manufacturing facilities, and quality assurance labs where consistent hardness verification is required. Technicians typically keep a testing file on hand to check instrument function at the start of a shift or after equipment maintenance. It is sold as a single-piece unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e45 RC hardness rating on the Rockwell C scale for mid-range verification\u003c\/li\u003e\n  \u003cli\u003eCompatible with most bench-type Rockwell and Rockwell Superficial hardness testers\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.05 pounds for easy bench storage and handling\u003c\/li\u003e\n  \u003cli\u003eSingle testing file per package for straightforward inventory management\u003c\/li\u003e\n  \u003cli\u003eSupports routine calibration checks and instrument performance verification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with most bench-type Rockwell and Rockwell Superficial type hardness testers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis testing file is used by quality control technicians and metrology professionals, not as an installed component. Before performing a verification test, ensure the hardness tester is powered on, properly zeroed, and that the correct indenter and load for the Rockwell C scale are in place. Follow the tester manufacturer's operating procedure when applying the file to the anvil. Handle the reference surface with care to avoid scratches or contamination that could affect readings.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScale Type\u003c\/strong\u003e: Rockwell C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Hardness\u003c\/strong\u003e: 45 RC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFile Set Type\u003c\/strong\u003e: Testing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Equipment\u003c\/strong\u003e: Most bench-type Rockwell and Rockwell Superficial type hardness testers\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41114600\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 98-722-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51692574474546,"sku":"98-722-2","price":65.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64a5e1718cf4bb8816fd19071a8ca885.jpg?v=1788299554","url":"https:\/\/voomisupply.com\/products\/spi-98-722-2-rockwell-c-scale-testing-file-45-rc","provider":"Voomi Supply","version":"1.0","type":"link"}
