Thin film testing grips.X17 thin film grips are said to prevent slippage Slippage The difference between estimated transaction costs and the amount actually paid. Notes: Slippage is usually attributed to a change in the spread. See also: Spread, Transaction Costs Slippage or breakage of thin rubber samples when tested for tensile strength tensile strength Ratio of the maximum load a material can support without fracture when being stretched to the original area of a cross section of the material. When stresses less than the tensile strength are removed, a material completely or partially returns to its . Difficulties are often encountered when testing samples cut from thin sheets made of latex rubber and other highly extensible materials, according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. the company. Products made by dipping NR latex can extend by up to ten times their original length, and are often coated with a lubricant. Therefore, slippage or breakage at the grips are said to frequently invalidate tests. A combination of clamping and capstan capstan Mechanical device used chiefly on board ships or in shipyards for moving heavy weights by means of ropes, cables, or chains. A capstan consists of a drum, driven either manually or by steam or electricity, that rotates about a vertical axis to wind in a line wrapped effects in the thin film grips is said to overcome these problems. The X17 grips achieve a 360[degrees] wrap-around of the sample, which due to the exponential relationship of the capstan effect, squares the gripping friction on the sample. Originally designed for testing latex samples up to 25 mm wide, the grips are also said to be suitable for compliant elastomeric material, paper, fabric and threads less than 0.2 mm in thickness. The X17 grips are opened and closed by a simple thumb and forefinger forefinger /fore·fin·ger/ (-fing-ger) index finger; the second finger, counting the thumb as first. fore·fin·ger n. See index finger. action, according to the company, and are provided with a tab end which can be secured quickly by conventional tensile tester grips. (Wallace Instruments, P.O.
