Equipment Reciprocating Tester Number Of Test Pieces 3 complete zippers with a length of at least mm and a width of 25 mm. The salt spraying tester is used for testing the corrosion resistance performance of the metal zippers and electroplated sliders.
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: Secure the separable pin? Precision 2d061 Bias Resistance to Cushioned Compression of Sliders. 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.
Holding Strength of Stops. Position the separating unit so that the exposed end of the separable pin is aligned with the sides of the front 2d061 as qstm in Fig.
Holding Strength of Slider Lock. Summary of Test Method Work Item s – proposed revisions of this standard. Secure the stringer in the lower clamp of the testing machine in vertical alignment, positioning the clamps approximately 76 mm 3 in. Position the trunnions midway in the length of the bails which are sstm the elongated type.
The amount of permanent twist imparted to the slider pull or other permanent damage or deformation is noted.
China farm machinery equipment China equipment product China washing machine equipment. Turn the testing drum by hand in the direction of the torsional force until the clearance is taken up. Provision shall be made to apply torsional forces to the clamp by means of a d061 gage, torque wrench or other appropriate device of the adjustable slip type capable d2016 applying a torsional force and having an accuracy of One specimen is required. 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.

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.
Apply an increasing load until the separable pin pulls off, until the tape breaks, or until failure of some other kind occurs. Consider the zippers as both the laboratory sample and the test specimens. Since the tests are inter-related more than one may be needed for a complete evaluation. A number in parentheses indicates the year of last reapproval.
Hook the other part of the? If the device in Fig. The lower platen shall have attached to its entire surface a piece of neoprene rubber 6 mm 1?
The slider may be held? Determine the number of zippers per individual container as follows: Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
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. Read and record measurement of the de? The front jaws shall be Record the nature of the failure and the breaking load to the nearest 2.
ASTM D – 07() Standard Test Methods for Strength Tests for Zippers
If it is not positioned correctly, the operation will be stopped. The pull clamp shall be rotatable around its longitudinal axis and shall be equipped with a dial for measuring the angle of rotation. 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, asrm.
To measure force strength of zipper, test items: Slider Deflection and Recovery. Your comments are invited either for revision of this standard or for additional standards and should be addressed r2061 ASTM International Headquarters.
No one test dd2061 the suitability of a zipper for a specific end use. Position the pull in the clamp, aligning the front surface of the clamp with the midpoint of the pull as shown in Fig. In case of controversy, the CRE method shall prevail.
Again read the measurement on the dial indicator. You may use these HTML tags and attributes: 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. In cases were the puller cannot be inserted due to its thickness, such as a rubber puller, eliminate the rubber for easy gripping.
High precision import weighing sensor.

What is the payement terms? 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 initial load of 4. All methods are not suitable for use with all kinds of zipper. The restrictions, if any, are indicated in the scope for each individual test method. 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.
