Zipper Axtm Testing Instrument The zipper reciprocating testing instrument is used for testing the anti-fatigue performance of the zippers through the reciprocating opening and closing of the zipper sample under the vertical and lateral tension.
Set the number of test cycle. And the test time varies from customer to customer.
Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. Place the zipper in the downwards position and ensure the puller faces backwards so that puller can be fixed by the clamp figure 4.
China package equipment China rowing machine equipment China filling equipment.
Position the slider body at the point where normally checked in its free movement by the stop or stops to be tested. Work Item s – proposed revisions of this standard. The amount of permanent twist imparted to the slider pull or other permanent damage or deformation is noted. Your email address will not be published. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Record the nature of the failure and load at failure to the nearest 2.
Forces up to 10 kN 2, lbf Low force tabletop systems Modular series of five frame options with adjustable test space Affordable testing option for tension, compression, bend, peel and much more.
Connect the pull to the top clamp of the tensile testing machine with a suitable hook or thong so that the pull is at a right angle to the slider body. Read and record measurement of the de? Last previous edition approved in as D — Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are aztm their own responsibility.
The position of the pull at this point will be the starting point for the second test in the counterclockwise direction. In cases were the puller cannot be inserted due to its thickness, such as a rubber puller, eliminate the rubber for easy gripping. Position the trunnions midway in the length of the bails which are of the elongated type.
Ast, farm machinery equipment China equipment product China washing machine equipment. Reciprocating Test for All Zippers: 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.
Apply an increasing load until the retainer pulls off, until the tape breaks, or until failure of some other kind occurs. Atomic Absorption Spectrophotometer The atomic absorption spectrophotometer is mainly used for testing the content of harmful heavy metals involved in such raw materials as zinc alloy, metal accessories, paint, etc. You can choose d2016 one which is most convenient or cost effective for you.

Apply the load required by the applicable speci? Again read the measurement on the dial indicator.
Cut the tape with sharp scissors, cutters or nippers using single stroke, ignoring blooming if it occurs. Apply an increasing load until the stop or stops pull off, until the tape breaks, or until failure of some other kind occurs. Force range of 5 kN to 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.
Electronic Universal Tensile Testing Machine 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 s2061 belts based on different fixtures.
Apply an increasing load until the asgm pull off the bead, until the tape separates, or until failure of some other kind occurs. Salt Spraying Tester The salt spraying tester is used for testing the corrosion resistance performance of the metal zippers and electroplated sliders.

The ability of the pull and slider to resist the speci? This number of specimens is calculated using values of v which are somewhat larger values of v than are usually found in practice. Usually we quote within 12 hours after we get your enquiry.
Test methods for measuring those properties have not been published either because no practical methods have yet been developed or because a valid evaluation of the information resulting from existing unpublished methods requires an intimate and thorough knowledge of zippers. No one test determines the suitability of a zipper for a specific end use.
Locate and lock the slider midway between the ends of the chain.

Precision and Bias Continue turning the torque device in the counterclockwise direction until a load begins to be applied. In addition the amount of permanent twist imparted to the slider pull or other permanent damage or deformation may be noted. You may use these HTML tags and attributes: Secure one of the stringers emerging from the throat of the slider in the upper clamp and one in the lower clamp of the testing machine.
The effects of operability of the zipper is then determined. Significance and Use 4. If a bias is found, either its cause must be found and corrected, or future test results must be adjusted in consideration of the known bias.
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. They can be used as aids in the evaluation of zippers without the need for a thorough knowledge of zippers.
