5 Sampling and conditioning
5.1 Conditioning of samples and all other test consumables (e.g. abrasive paper, EPDM, cotton canvas) is as follows:
5.2 If the test is performed in a different environment and if the testing duration does not exceed 15 min, it shall be started within 5 min after removal from the conditioning.
5.3 If special applications require testing in a different environment, it is the responsibility of the manufacturer or his authorized representative to arrange for additional tests and to present the results including a full description of the testing environment in the information supplied by the manufacturer (Clause 8).

6.4.4 Setting up the test specimen
6.4.5 Test method
6.4.5.1 The tearing force is recorded on a X-Y recorder at a tensile test speed of (100 ± 10) mm/min. The specimen shall be torn totally apart. Note that in some cases the tearing may not be in the longitudinal direction of the specimen.
6.4.5.2 If the specimen is not fully torn apart under a force in excess of 75 N, then the test may be stopped and the maximum force reached is recorded.
6.4.5.3 The test shall be performed on one specimen cut from each of four different gloves of the same glove series.
6.4.5.4 Two specimens shall be tested in the direction of the glove from cuff to finger tips, and two specimens shall be tested across the palm width (see Figure 7).
6.4.5.5 The tear resistance for each specimen is taken as the highest peak recorded, and the classification is determined by taking the lowest of the individual values.

C.1 Objective
C.2 Apparatus and materials
C.2.1 Tensile-testing machine, incorporating the following features:
C.2.2 PVC-plate, comprising a piece of hard poly(vinyl chloride) (PVC), measuring approximately 70 mm × 20 mm × 3 mm, to which the leather specimen is bonded. PVC with a high infrared (IR) absorption is preferred.
C.2.3 Adherent-plate holder (see Figure C.1), made of any suitable material, for holding the adherent- plate, to which the leather specimen has been bonded, in the lower clamp of the tensile-testing machine. Optionally, the plates can be held firmly by screws through the sides of the plate holder (see Figure C.3).
C.2.4 Hook link, made of steel wire 1 mm to 2 mm in diameter, at least 200 mm long, for attaching the free end of the leather specimen to the upper clamp of the tensile-testing machine (see Figure C.3). The length of the hook link ensures that the angle of peel always remains close to 90°.
C.2.5 Punch, suitable for making a hole 2 mm to 3 mm in diameter in the leather reference rubber specimen, if using the hook link (C.2.4).
C.2.6 Reference rubber (see ISO 4649:2010, Annex B), dimension of the piece of rubber to be tested, 100 mm ± 2 mm × 10 mm ± 1 mm.
C.3 Preparation of test specimens
C.4 Test procedure
C.4.1 Fix the holder (C.2.3) in the lower clamp of the tensile-testing machine (C.2.1).
C.4.2 Slide the conditioned test specimen (PVC-plate / test specimen / reference rubber) into the holder until one end of the plate is flush with one end of the holder.
C.4.3 Attach one end of the hook link (C.2.4) in the upper clamp of the tensile-testing machine and attach the other end to the leather specimen by hooking it into the hole at the end of it (see Figure C.3).
C.4.4 Set the tensile-testing machine to a uniform speed of separation of the jaws of 100 mm/min and record the force-distance diagram for the separation of the reference rubber from the test specimen of 30 mm to 35 mm.
C.4.5 The force shall be applied such that the reference rubber peels off at an angle of about 90° to the PVC-plate.
C.4.6 For each force-distance diagram, shown schematically in Figure C.4, determine the mean force during the peel propagation of the test specimen, i.e. the adhesion value. Record this adhesion value, expressed in newtons per mm, rounded to the nearest 0,01 N/mm.
C.5 C.5 Examples of acceptable adhesive tape
