Rated at 55 RC maximum hardness, this testing file provides a reference standard that technicians and quality control professionals rely on to confirm their bench-type hardness testing equipment is performing within specification. It is a single-piece reference file designed for use in lab, shop, and industrial settings where hardness testing accuracy is critical.\u003c\/p\u003e\n\u003cp\u003eThis testing file is suited for use with most bench-type Rockwell and Rockwell Superficial hardness testers found in quality assurance labs, machine shops, heat-treating facilities, and manufacturing environments. Metrology technicians, QC inspectors, and tooling specialists use reference files like this to perform routine equipment verification checks before running production hardness tests on metal components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRockwell C Scale reference file rated to 55 RC maximum hardness\u003c\/li\u003e\n  \u003cli\u003eCompatible with most bench-type Rockwell and Rockwell Superficial hardness testers\u003c\/li\u003e\n  \u003cli\u003eProvides a traceable reference point for equipment calibration verification\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.05 pounds for easy bench storage\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package quantity for straightforward inventory management\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 handled by metrology technicians or QC personnel performing hardness tester verification. Before use, ensure the hardness tester is on a stable, vibration-free surface and has been allowed to reach thermal equilibrium per the equipment manufacturer guidelines. Handle the reference file carefully to avoid surface damage, as nicks or contamination on the test surface can affect reading accuracy. Follow applicable ASTM or equipment manufacturer procedures when performing verification tests.\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: 55 RC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFile Set Type\u003c\/strong\u003e: Testing\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\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: 98-724-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51720744894770,"sku":"98-724-8","price":90.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bb63fa94cdcaf643e3749b633ba67bfa.jpg?v=1788568516","url":"https:\/\/voomisupply.com\/products\/spi-98-724-8-rockwell-c-scale-testing-file-55-rc","provider":"Voomi Supply","version":"1.0","type":"link"}
