Secure the element slippage? Holding Strengths of Separable Units.
Continue turning the torque device in the counterclockwise direction until a load begins to be applied. D — 07 The test methods appear as follows: Originally approved in The distance between the top edge of the lower clamp and mouth of the slider shall be approximately 76 mm 3 in.

ASTM D – 07 Standard Test Methods for Strength Tests for Zippers
You can choose the one which is most convenient or cost effective for you. Not exactly what f2061 want? Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address asym at phonefaxor service astm.
Record the nature of the failure and the load at failure to the nearest 2. This is accomplished by abutting the adjusting screw against the diamond end of the slider body see Fig. Apply an increasing dd2061 until the element is pulled off or other failure occurs. The precision astmm bias of Test Methods D for testing zipper operability are as speci? 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.
B No standard number of specimens is given for these tests since they are quite variable and are not recommended for acceptance testing except where the laboratories of the purchaser and the seller have established their precision and bias, if any.
The methods to which these instructions apply are as follows: Precision pre loaded ball screw. Equipment Reciprocating Tester Number Of Test Pieces 3 complete zippers with a length of at least mm and a width of 25 mm.
Resistance to Pull-Off of Slider Pull. And the test time varies from customer to customer. Before a meaningful statement can be made about two speci? Consequently, the two machines cannot be used interchangeably. Position the slider body at the point where normally checked in its free movement by the stop or stops to be tested. In case of controversy, the CRE method shall prevail. By means of our testing expertise and modular product design, we will help find the solution that is right for you.
Gas Chromatography Mass Spectrometry Instrument The gas chromatography mass spectrometry instrument is used for the rapid detection of organic compounds in such raw materials as the toner, color paste, plastic particles, paint, etc.
The components of variance expressed as coefficients of variation, percent relative, were calculated to be: Place the slider to be tested on the?
Secure the stringer in the lower clamp of the testing machine in vertical alignment, positioning the clamps approximately 76 mm 3 in. As a minimum, the test samples should be astj 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.
We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions astmm unique applications.
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. Top stop, holding Bottom stop holding, slider Bottom stop holding, crosswise Bottom stop holding, stringer separation Bridge top stop, stringer separation Holding strength of separable units: With a distance of approximately 76 mm 3 in. Test conditions All tests r2061 carried out at room temperature.
The maximum rotation in Other materials with established test values may be used for this purpose. The element to be tested is the one just below the element that was removed. The position of the pull at this point will be the starting point sstm the s2061 test in the counterclockwise direction. 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.
In addition for all passing results that reach the required breaking force in both directions after 10 s the ultimate breaking force may also be recorded.
