Apply an increasing load until the stop pulls off, until the tape breaks, or until failure of some other kind occurs. Two specimens are required. We are confident that we have what you are looking for. 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. The top plate of the?
The compression testing machine shall be designed to permit the application of a load to the platens at a rate-of-traverse of approximately 13 mm 1? Set the opposing clamps of the testing machine approximately 76 mm 3 in. All 64 specimens of each material came from the same sample. The test methods appear as follows: Cut the tape with sharp scissors, cutters or nippers using single stroke, ignoring blooming if it occurs.
Supplier Assessed videos Factory inspection reports Verified production lines. Equipment Reciprocating Tester Number Of Test Pieces 3 complete zippers with a length of at least mm and a width of 25 mm.
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. Apply an increasing load until the element slips off the end of the cut bead or until other failure occurs. Chain crosswise strength Element pull-off Element slippage, lengthwise Holding strength of stops: If it is not positioned correctly, the operation will be stopped.
Apply a compression force astk a rate-of-traverse of approximately 13 mm 1? 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.

Work Item s – proposed revisions of this standard. Apply an increasing load until the elements pull off the bead, until the tape separates, or until failure of some other kind occurs. High rigid frame load frame. The restrictions, if any, are indicated in the scope for each individual test method. Place the slider mouth over the selected nibs on the slider de? Reduce the xstm to 4.
Slider Deflection and Recovery. Support online communication, data using RS transmission.
ASTM D2061 resistance strength apparatus puller attachment testing machine equipment
The ends of the front jaws shall be at least 25 mm 1 in. Test modular design, open data management, can realize load, deformation, displacement, variable speed control 7. Leave a Reply Cancel reply Your email address will not be published.
The test results from the two laboratories should be compared using a statistical test for unpaired data, at 1. The slider may be held? Resistance to Pull-Off of Slider Pull. Ashm the load until the stop pulls apart, until the tape breaks, or until failure of some other kind occurs.
Besides d20661 properties measured by means of the enumerated test methods there are other properties that may be important for the satisfactory performance of a zipper.
Reciprocating Test for All Zippers: BS 3084, DIN 3419, ASTM D 2061, JIS S 3015
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. Position the trunnions midway in the length of the bails which are of the elongated type. China farm machinery equipment China equipment product China washing machine equipment.
This number of specimens is calculated using values of v which are somewhat larger values of v than are usually found in practice. The pull clamp shall be rotatable around its longitudinal axis and shall be equipped with a dial for measuring the angle of rotation.

The amount of permanent twist imparted to the slider pull or atm permanent damage or deformation is noted. Place the slider body in the?
They can be used as aids in the evaluation of zippers without the need for a d206 knowledge of zippers. Historical Version s – view previous versions 2d061 standard. In the other, which is an aastm method, the force is applied through the slider pull and back plane of the slider. Since the tests are inter-related more than one may be needed for a complete evaluation. 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.
To measure force strength of zipper, test items: 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. The components of variance expressed as coefficients of variation, calculated as percentage of the average were:
