ASTM D2061 – Standard Test Methods for Strength Tests for Zippers

ASTM D2061 covers the determination of the strengths for zipper and zipper parts. All methods are not suitable for use with all kinds of zipper.

RESISTANCE TO ANGULAR PULL-OFF OF SLIDER PULL

This test method covers the determination of the resistance to pull-off of the pull in a pull-and-slider zipper assembly, the pull being at 135° to the top planes

of the slider as rotated from the mouth end.

---

ASTM D2061 / Summary of Test Method

A special fixture as shown in Fig. 20 is used with a tensile testing machine to apply a load through the pull to the slider of the zipper.

Significance and Use

Resistance to Angular Pull-Off of Slider Pull—This test method may be used to determine slider pull strength which measures the resistance of the pull or

pull assembly, either or both, to rupture, deformation or separation when a stress is applied at an angle during operation of the zipper in the end-product.

ASTM D2061 / Apparatus

Testing Machine

Angular Pull Fixture  to hold the slider body as shown in Fig. 20.

---

Test Specimen

The test specimen shall consist of a complete pull-and slider assembly.

---

ASTM D2061 / Procedure

Secure the angular pull fixture in the upper clamp of the testing machine.

Place the slider body in the fixture, with the pull projecting vertically downward, so that both the bail and the pull are clear and unrestricted.

This is accomplished by abutting the adjusting screw against the diamond end of the slider body (see Fig. 20).

Hook the other part of the fixture into the pull and then secure it in the bottom clamp of the testing machine.

Apply the load required by the applicable specification.

*** Before conducting ASTM D2061 , it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
