The Gelbo Flex Tester has been designed to determine the flex resistance of flexible barrier materials by applying repetitive strain. Pin hole formation is the criteria for failure and are determined by use of colored turpentine by allowing it to stain through the pin holes onto a white backing.

 

While the sample is being subjected to repetitive twisting and compression cycles on the Gelbo Flex Tester, air is withdrawn from the testing chamber and the particles in the air stream are counted and classified on the particle counter.

Basic Structure:

1. Dry lint generator

1) Torsion device: to exert comprehensive force of torsion, compression and recovery

2) Torsion chamber (electrostatic resistance) : an organic glass body with electrostatic resistance which covers the torsion device

3) Air sampler: fixed on a specific location in the torsion chamber. The sample port has a certain shape.

2. Laser dust particle counter

Count and classify the particles in the sampled air.
