23、NOTE: The following items are convenient, but non essential parts of the equipment: - means to move the finger at right angles to the direction of rubbing, so that two or three tracks may be used for rubbing on one test piece; means for pre-selecting a given number of cycles. 4.4 Felt pads, comprisi

For each test piece, place four felt pads (see 4.4) and four pieces of abradant fabric (see 4.5) in distilled wate
29、r, heat to boiling and allow to continue boiling gently until they sink. Then decant the hot water and replace with cold, distilled water. Leave the pads and abradant fabric until they have reached room temperature. Before use, take each pad and abrasion fabric from the water and squeeze or wipe it
30、against the rim of a beaker so that it no longer drips.

NOTE; The pads and abradant fabric should not be allowed to soak in water for more
31、 than 24 h before use. Fasten the test piece on to the apparatus described in 4.1, 4.2 and 4.3, and apply a slight tension to hold it flat. Attach a wet felt pad to the finger, cover with a rectangle of wet abradant fabric and secure it to the finger with, for example, a rubber band or ring, avoidin
32、g any crease in the fabric over the surface of the felt pad. Place the finger 5 mm from one edge of the test piece. Attach the additional mass of 500 g to the finger. Carry out 1 O0 cycles, lift the finger, and examine the test area for abrasion damage. Replace the felt pad and abradant fabric with
33、fresh ones and carry out a further 100 cycles. Replace the felt pad and abradant fabric every 100 cycles and stop the test when the abrasion damage of the test piece is equal to, or more severe than the “acceptable“ degree of abrasion of the corresponding “reference test piece“, or after 400 cycles,
34、 whichever occurs first. 7 Expression of results I Examine the abraded surface of the test piece visually in order to evaluate the abrasion damage by comparison with “reference test pieces“ of the same family of materials. The result will be the worse of the assessment of the three test pieces. 8 Te
