Apply an increasing load until the elements pull off the bead, until the tape separates, or until failure of some other kind occurs.
Instead, specify the number of specimens shown in Table 1. Leave the asrm spacer in place throughout the test. To measure force strength of zipper, test c2061 Two specimens are required. 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.

The platens shall be hardened steel, 51 by 51 by 25 mm 2 by 2 by 1 in. Asgm the clamp in this position, insert the puller into the clamp and fix with the screw. 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.
Test methods atsm 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no practical methods have yet been developed or because a valid evaluation of the information resulting from existing unpublished methods requires an intimate and thorough knowledge of zippers.
Remove the second element from the top of the stringer, taking care not to damage the bead. Since the tests are inter-related more than one may be needed for a complete evaluation.
Record the nature of the failure and the load at failure to the nearest 0. Compliance Checklist for Garments Factory. Record satm nature of the failure and the load at failure to the nearest 2.
Consider the zippers as both the laboratory sample and the test specimens. Consequently, the two machines cannot be used interchangeably. Before a meaningful statement can be made about two speci? The restrictions, if ast, are indicated in the scope for each individual test method.
The distance between the top edge of the lower clamp and mouth of the slider shall be approximately 76 mm 3 in. Secure the element slippage? The qstm test methods do not provide for the evaluation of all zipper properties.
Test modular design, open data management, can realize load, deformation, displacement, variable speed control. 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.
Examine each specimen to determine whether or not there remains the usual ease of manual movement of the pull.
ASTM D – 93() Standard Test Methods for Strength Tests for Zippers
Historical Version s – view previous versions of standard. All methods are not suitable for use with all kinds of zipper.
Secure the stringer in the lower clamp of the testing machine in vertical alignment, positioning the clamps approximately 76 mm 3 in. Release the compression force, remove the specimen from the apparatus and test it for operability as directed in The effects of operability of the zipper is then determined.
If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
Reciprocating Test for All Zippers: BS 3084, DIN 3419, ASTM D 2061, JIS S 3015
We are confident that we have what you are looking for. Besides those properties measured by means of the enumerated test methods there are other properties that may be important for the satisfactory performance of a zipper. Record the nature of the failure and load at failure to the nearest 2.
This surface scanning method asttm not cause any damage. If it is not positioned correctly, the operation will be stopped.

Current edition approved Jan. Contact Supplier Start Order. A superscript epsilon e indicates an editorial change since the last revision or reapproval. If the design permits lengthwise travel of the pull along a lug or cap, the pull should be positioned so that it is midway in its length of travel.
In addition the amount of permanent twist imparted to the slider pull or other permanent damage or deformation may be noted. Apply an increasing load until the element slips off the end of the cut bead or until other failure occurs. No one test determines the suitability of a zipper for a specific end use. The load shall be measurable in increments of 44 N 10 lbf. Position the slider at the point FIG.
