Precision and Bias Other materials with established test values may be used for this purpose. Apply a compression force at a rate-of-traverse of approximately 13 mm 1? Consequently, the two machines cannot be used interchangeably. The pull clamp shall be rotatable around its longitudinal axis and may be equipped wstm a dial for measuring the angle of rotation.
This is accomplished by abutting the adjusting screw against the diamond end of the slider e2061 see Fig. The front jaws shall be With a distance of approximately 76 mm 3 in.
Release the torsional force. You can choose the one which is most convenient or cost effective for you.
Holding Strength of Slider Lock. Again read the measurement on the dial indicator. Separable pin Fixed retainer Separating unit—crosswise Slider de? Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement x2061 such rights, are entirely their own responsibility.
Secure the stringers in the upper and lower clamps of the testing machine with the slider body positioned along the axis of the clamps and midway between them as shown in Fig. All methods are not suitable for use with all kinds of zipper.
It is also used for inspecting the influence of shrinkage on the elongation of the zipper products based on the simulated garment shrinkage test performed. Secure the stringer in the bottom clamp of the testing machine as described in Resistance to Pull-Off of Slider Pull. Position the slider body at the point where normally checked in its free movement by the stop or stops to be tested.
Chain crosswise strength Element pull-off Element slippage, lengthwise Holding strength of stops: No one test determines the suitability of a zipper for a specific end use. The pull clamp shall be rotatable around its longitudinal axis and shall be equipped d20661 a dial for measuring the angle of rotation.
Holding Strength of Stops.

The element to be tested is the one just below the element axtm was removed. Consider the zippers as both the laboratory sample and the test specimens. The electronic universal tensile testing machine is used for testing the anti-tensile strength and elongation of the copper wires, welding wires, plastics, polyester yarns and steel belts based on different fixtures.
Insert the selected diamond spacer transversely through the slider as shown in Fig. Have a question about conducting the test for this standard? This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Summary of Test Method In the other, which is an alternative method, the force is applied through the slider pull and back plane of the slider.
Force range of 5 kN c2061 kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column testers are available in both tabletop and floor standing models.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Secure the element slippage?
This number of specimens is v2061 using values of v which are somewhat larger values of v than are usually found in practice. Apply an increasing load until the separable pin pulls off, until the tape breaks, or until failure of some other kind occurs. Position the separating unit so that the exposed end of the separable pin is aligned with the sides of the front jaws as shown in Fig.
ASTM D resistance strength apparatus puller attachment testing machine equipment. The enumerated test methods do not provide for the evaluation of all zipper properties. Reciprocating Test for All Zippers: Locate and lock the slider midway between the ends of the chain. Secure the two stringers in the lower clamp of the testing machine as illustrated in Fig. Holding Strengths of Separable Units. In one procedure the force is applied to the mouth of the slider.
Support online communication, data using RS transmission 9. NOTE 1—An adequate speci? Salt Spraying Tester The salt spraying tester is used for testing the corrosion atm performance of the metal zippers and electroplated sliders.
Hook the other part of the? The X-ray fluorescence analyzer is mainly used for screening the content of chemical elements in the semi-finished products, finished zippers and certain raw materials, including lead, cadmium, chromium, mercury, arsenic, barium, antimony and selenium as well as analyzing the unknown components in the samples.
