Ames Test Blocks for Portable Hardness Testers
Ames test blocks, like our portable hardness testers are certified to meet ASTM 110 standards. Each new Ames test block is calibrated and certified for use with our hardness testers. We offer standard and superficial test blocks in hard steel, soft steel and brass. We can also provide test blocks that meet your specifications when you special order. Each test block we sell comes with a certificate verifying the certified test block value. Use your Ames test blocks to perform regular accuracy checks to ensure your Ames tester is reading accurately. Your tester reading should match the hardness on the test block within +/-1. If you are receiving incorrect readings, send your tester in for calibration. Purchase new Ames test blocks when your test block has been used to maximum recommended test indentations. Ames test blocks are serialized and traceable to national standards. Available in all scales.
All AMES Hardness Testers, whether in constant use or not, require accuracy checks. To check accuracy, take several readings on the test block. The readings on the barrel dial should agree with the marking on the test block.
Always apply the penetrator to the same side of the test block, only on areas not marked by previous tests. When you cannot be certain of placing the penetrator on a perfectly unaffected part of the surface, you need a new test block.
