You may use these HTML tags and attributes: Separate the chain into stringers and hold a stringer so the elements are positioned as in Fig. 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.

Zipper Reciprocating Asttm 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. Compliance Checklist for Garments Factory. 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.

Apply an increasing load until the elements pull off the bead, until the tape separates, or until failure of some other kind occurs. Other materials with established test values may be used for this purpose.

The compression testing machine shall be designed to permit the qstm of a load to the platens at a rate-of-traverse of approximately 13 mm 1? To measure force strength of zipper, test items: Link to Active This link will always route to the current Active version of the standard. Open the chain by pulling the stringer apart all the way to the bottom stop.


Current edition approved Jan. High precision import weighing sensor 3. One specimen is required. The enumerated test methods do not provide for the evaluation of all zipper properties. Read and record measurement of the de?

ASTM D2061 Zipper strength Testing Equipment

The load shall be measurable in increments of 44 N 10 lbf. China farm machinery equipment China equipment product China washing machine equipment. Each laboratory used two operators to test each material.

Resistance to Cushioned Compression of Sliders. Should the pull reach the required force after the 10 s has elapsed in the counterclockwise direction the pull may be tested to failure by continuing to turn the loading device in the counterclockwise direction until breakage occurs.

In one procedure the force is applied to the mouth of the slider. All methods are not suitable for use with all kinds of zipper.

Apply the load until the stop pulls apart, until the tape ast, or until failure of some other kind occurs. Describe the material or product sampled and the method of sampling used.

ASTM D Zipper strength Testing Equipment

Summary of Test Methods Asym 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. This surface scanning method will not cause any damage. Determine the number of zippers per individual container as follows: Release the compression force, remove the specimen from the apparatus and test it for operability as directed in 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.


No one test determines the suitability of a zipper for a specific end use. Turn the testing drum clockwise until the clearance between the lug and the pull trunnions is taken up, and then set the dial to zero.

Last previous edition approved in as D — 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.

In the case of the entering type bottom stop, position the slider at the point where normally checked in its free movement. By means of our testing expertise and modular product design, we will help find the solution that is right for you. 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 steel belts based on different fixtures.
