In tensile testing or crush testing the accuracy of test results is not only dependent on the accuracy with which the procedure is carried out, but also on the accuracy of cutting the crush or tensile test samples. Some tests, for example, tensile strength and edge crush, are particularly sensitive, and cutting accuracy is a prime cause of variation in the values obtained. This model shows 3 precision tensile sample cutters and 2 crush sample cutters that are designed to eliminate the causes of errors associated with hand-cut samples.
