ASTM D2061
No one test determines the suitability of a zipper for a specific end use. Since the tests are inter-related more than one may be needed for a complete evaluation.

Fundamentals of Torque Testing
If you have ever struggled to open your favorite bottle of water or jam or required help loosening the lug nuts on your car’s wheels, it is likely due to a case of over-torque.

Compressive shear
Compressive shear testing is simply the pushing apart of a material specimen by applying compressive force from opposite sides in a parallel plane. In this way, the material is stressed in a sliding motion.

Friction
'Dry' friction (as opposed to 'fluid' or 'lubricated' friction) is the force resisting lateral motion between two solid surfaces in contact.
It divides into:

Flexure
Flexural or bend testing is used It is a way of determining how something will react when it is put under opposing forces across a span.to evaluate both the ductility and soundness of a material.

double lap shear
Lap shear testing is used where an adhesive bond joins flat surfaces.
The required surfaces may be profiled, single, double or multiple, but standard test methods focus on a single joint.

single lap shear
Lap shear testing is used where an adhesive bond joins flat surfaces. The required surfaces may be profiled, single, double or multiple, but standard test methods focus on a single joint.

Insertion and withdrawal
Insertion and withdrawal testing involves applying and measuring the compressive force to an object to push it into a recepticle, then measuring the tension force to pull it out. This may be done for a single cycle or over multiple cycles.

Closure torque
Closures and caps must be applied tight enough to maintain a seal and to resist working loose, but they must not be applied so tightly that the end user cannot reasonably remove them.
