Rockwell Test Blocks

		Rockwell Test Blocks

Newage® test blocks for Rockwell scales are ideal for verifying your Rockwell hardness testing system. Rockwell test blocks serve as a reference, with each block having an average hardness value. The hardness value of each block is a nominal value. All blocks have a typical hardness variation based on the nominal value of the block. Typically, you should test and verify your hardness testing system daily against a Newage test block. Newage test blocks for the Rockwell scales include Yamamoto and “routine” type blocks. NIST certification is available for Rockwell C Scale test blocks. Features & Benefits Meets ASTM E18-00 Section C Yamamoto and routine block types Include nominal face value with tolerance Some blocks are available with NIST certification (C Scale only)
