Spi 98-722-2 Rockwell C Scale Testing File 45 Rc

Product Description

The SPI 98-722-2 is a Rockwell C scale testing file rated at 45 RC, used to verify the calibration and performance of hardness testing equipment. 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.

This 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.

Compatibility

Designed for use with most bench-type Rockwell and Rockwell Superficial type hardness testers.

Installation Notes

This 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.
