What is the standard of zipper test?

 

ASTM D2061 provides several test methods to evaluate the strength and performance of zippers. Some of the commonly used test methods from this standard include:

 

1. Test Method A:
Straight Tensile Test - This method measures the maximum force required to separate the two sides of a zipper tape in a straight line.

 

2. Test Method B:
Crosswise Tensile Test - It evaluates the maximum force required to separate the two sides of a zipper tape perpendicular to the length.

 

3. Test Method C:
Top Stop Holding Strength Test - This method assesses the resistance of the top stops (the metal or plastic elements at the top end of the zipper) against pull-off forces.

 

4. Test Method D:
Slider Locking Test - It determines the ability of the slider to lock the zipper chain in place and resist movement when subjected to a specified load.

 

These are just a few examples of the test methods provided by ASTM D2061. The standard also covers additional tests, such as seam slippage, bottom stop strength, and slider pull-off strength.

 

It is crucial to consult the specific standards applicable to your industry or product requirements. In addition to ASTM, there might be other international or industry-specific standards that provide guidelines for zipper testing, such as ISO or AATCC standards.
