6.1.2.2 Double-sided adhesive tape
The double sided adhesive tape shall be used to provide adhesion of the sample during the test to achieve reproducible results. The mean adhesion value shall be of minimum 0,20 N/mm.
Tests are carried out according to the method given in Annex C.
NOTE 1 If the adhesion is not sufficient, the sample will move during the test and in this case a tear phenomenon can be observed rather than abrasion.
NOTE 2 Examples of suitable double sided adhesive tapes are provided in C.5. Alternative tapes can be verified for suitability using the test method defined in Annex C.
6.1.3 Apparatus
An abrasion machine of the type described in EN ISO 12947-1 as a Martindale Wear and Abrasion is required. It shall fulfil the following requirement:
Pressure on specimen: (9,0 ± 0,2) kPa.
6.1.4 Test specimens
Four test specimens shall be taken from four individual gloves of the same glove series. In case of an irregular design of the palm, the test specimen shall be taken in the area where the least protection is expected (remove the reinforcements that do not cover the whole palm).
Where the test specimen is made of several unbounded layers, the test is performed on each layer. When the specimen is made of bonded layers if the layers can be separated without damaging the material, the test must be performed on each layer independently. Otherwise, the test must be performed on all layers, taking care not to have a seam in the test area.
6.1.5 Test procedure
6.1.5.1 Setting up the machine
6.1.5.1.1 Mounting test specimens
Cut four test specimens to the correct dimensions, diameter (38,0 ± 0,5) mm. Secure the test specimen without tension carefully and centrally on the metal insert by means of double-sided adhesive tape under a weight of approximately 10 kg applied for at least 5 mm. Good adhesion can be achieved through the use of double-sided tape which prevents loosening of the test specimen and the inclusion of air bubbles. Place the ring of the specimen holder in position on the mounting plate provided on the base of the machine.
In order to test the materials that are thicker than the standard ring (for example leather with a thickness greater than 1,2 mm), the diameter of the opening of the clamping ring should be increased (see Figure 1).AS NZS 2161.3 pdf download.
