Abrasion

Samples are cut from the palm of a glove and rubbed against a 100 grit abrasive paper using a “Martindale” type abrasion machine. The number of cycles for the samples to hole is measured. Four performance levels are defined in EN 388 ranging from level 1 = holing > 100 cycles to Level 4 = holing > 8000 cycles.

Blade Cut

Samples are taken from the palm of a glove and the number of cycles to cut through the full thickness of the test sample by a circular rotating blade is recorded. Blade sharpness will vary and is assessed by using the cut test machine to cut through a standard reference fabric. The cut resistance of the glove is based on a relative index that compares the number of cycles to cut through the glove when compared with the standard fabric. Five performance levels are defined in EN 388 ranging from level 1 = Cut index > 1.2 to Level 5 = Cut index > 20.

Tear

“Trouser leg” type samples are taken from the palm of a glove and are torn apart using a standard tensile test machine. Four performance levels are defined in EN 388 ranging from level 1 = tear strength > 10 N to Level 4 = tear strength > 75 N.

Puncture

Samples are taken from the palm of a glove and the force required to penetrate the sample with a defined stylus using a tensile test machine is measured. Four performance levels are defined in EN 388 ranging from level 1 = Puncture force > 20 N to Level 4 = Puncture force > 150 N.
