3 Terms and Definitions

The following terms and definitions apply to this document. 3.1 Grab Test grabtest Widthwise central portion of the specimen holder is clamped tensile tester. Note. Under normal circumstances, the use of grab tensile strength determination when the sample width is 100mm. Holder with 25mm wide clamp the specimen surface at both ends of the middle ranks Bit, so that the tensile force to the center of the width of the specimen. 3.2 Elongation elongation Than the initial length of the sample and its increment due to the length of the force caused in percent. 3.3 Breaking strength breakingforce The sample was stretched to breaking off during maximum force. NOTE. In the most brittle material is usually strong at the broken off, ductile material typically occurs most vigorously before breaking off. 3.4 Tensile strength tensilestrength During stretching the stress test specimen. NOTE. Measure the sample at the time of unbroken able to withstand the force. Principle 4 The width of the specimen holder in the center of 100mm width 25mm of the clamp, to a predetermined tensile tester a tensile speed Broken off until the sample, the sample record breaking strength and elongation at break. ......
