Advancements in metals properties to improve performance characteristics have introduced materials to market that are stronger, tougher and many times more costly to produce. Tensile testing of these products can present a variety of gripping challenges. Use of a traditional grip arrangement consisting of a grip jaw or grip face will wear quickly and allow slippage. In addition, high production cost can mean limited material and shortened test samples. These are common challenges QC labs face and often lead to the need for machined, shoulder-end test specimens. Shoulder-end, or button-head test samples are outlined in ASTM E8, A370, A48, GOST 1497-1, as well as other general tensile test standards of metal products.
