A superscript epsilon e indicates an editorial change since the last revision or reapproval. Release the compression force, remove the specimen from the apparatus and test it for d0261 as directed in 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.
Since the tests are inter-related more than one may be needed for a complete evaluation. Multi-functional and easy to operate test software, equipped with a rich and increasing standard library of test methods. And the test time varies from customer to customer. The specimen is laid on the pad and a load applied.
Apply an increasing load until the separable pin pulls off, until the tape breaks, or until failure of some other kind occurs. The precision and bias of Test Methods D for testing zipper operability are as speci?
With a distance of approximately 76 mm 3 in. Historical Version s – view previous versions of standard. When a reliable estimate of v for the users laboratory becomes available, Eq 1 will usually specify fewer than the number of specimens shown in Table 1. Secure the element slippage? The distance between the top edge of the lower clamp and the nearest surface of the slider body shall be approximately 76 mm 3 in. High precision import weighing sensor 3.
Reciprocating Test for All Zippers: BS 3084, DIN 3419, ASTM D 2061, JIS S 3015
Leave a Reply Cancel reply Your email address will not be published. High speed, low adtm, high resolution digital closed loop controller for Japanese Panasonic AC servo drive. Record the nature of the failure and the breaking load to the nearest 2. Apply the load until the stop pulls apart, until the tape breaks, or until failure of some other kind occurs.
All methods are not suitable for use with all kinds of zipper. The loading 2d061 shall be a torque gage, torque wrench or other appropriate device of the adjustable slip type capable of applying a torsional force and having an accuracy of One specimen is required. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.
The components of variance expressed as coefficients of variation, percent relative, were calculated to be: NOTE 1—An adequate speci? Record the nature of the failure and load at failure to the nearest 2. The top plate of the?

A number in parentheses indicates the year of last reapproval. Place the slider body in the? By means of our testing expertise and modular product design, we will help find the solution that is right for you. Have a question about conducting the test for this standard? Holding Strength of Slider Lock. This number of specimens is calculated using values of v which are somewhat larger values of v than are usually found in practice.
No one test determines the suitability of a zipper for a specific end use. 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.
Apply an initial load of 4. Work Item s – proposed revisions of this standard.
As a minimum, the test samples should be used that are as homogeneous as possible, that are drawn from the material from which the disparate test results were obtained, and that are randomly assigned in equal numbers to each laboratory for testing. The lower d20661 shall have attached to its entire surface a piece of neoprene rubber 6 mm 1? High rigid frame load frame. ASTM D resistance strength apparatus puller attachment testing machine equipment. Cut the tape with sharp scissors, cutters or nippers using single stroke, ignoring blooming if it occurs.
Apply the load required by the applicable speci? The tape and bead may be cut either partially or completely across as long as the element to be tested is not hindered in its movement along the bead. Apply the load speci? From both stringers remove the elements adjacent to but not under the bottom stop for a distance of approximately 13 mm 1? Secure the zipper in the lower clamp of the testing machine as illustrated in Fig.
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. Support online communication, data using RS transmission 9. Number of Specimens 6. Place the pull in the normal? The methods to which these instructions apply are as follows: Determine the number of zippers per individual container as follows: Examine each specimen to determine whether or not there remains the usual ease of manual movement of the pull.
