4.3 preparation of apparatus, test specimens and conditioning.

4.3.1 preparation of apparatus

For conducting tests for abrasion according to:

ASTM D4966、BS 2543、BS 3424-24、BS 5690、BS 8428、ISO 12947

ISO 17704、ISO 5470-2、IWTO 40、M&S P19、Next 18、SFS 4328

SN 198529、TWC 112、Volvo 1024,7122

The abrasion table should be covered with a circle of felt which is either woven or non woven

(non woven only for M&S testing). These felts are both available from SBT.

The abrasion tables should then be covered with the standard abradant fabric. This should

conform to ISO 12947–1. This abradant is available from SBT.

For conducting tests for pilling, the abrasion table is first covered with the standard felt as

described above and then the tables are covered with a piece of the test specimen.

For testing for abrasion the specimen holders should be loaded with firstly a piece of standard

foam (available from SBT) and then the sample under test.

For testing for Pilling the sample holder is firstly covered with a piece of felt and then with the sample

under test.

4.3.2 Conditioning

All samples and standard fabrics should be conditioned in the standard atmosphere for testing

All abrasion and pilling testing should be carried out in the standard atmosphere for testing:

20°C ±2°and

65% RH ± 2%.

SECTION 5 TESTING PROCEDURES

5.1 Sample preparation - Abrasion

After conditioning of the samples and standard fabrics, from the test fabric cut 4,6, or 9 samples

according to the capacity of the machine.

These samples should be cut 38mm diameter this can be achieved using the SBT01M cutter.

Cut the same number of samples out of the foam felt.

From the standard abradant fabric cut the required number of samples (one for each station), these

samples should be cut 140mm diameter. This can be achieved using the SBT02M cutter.

2. Take one of the specimen holders, and unscrew the bottom of the holder which will reveal a brass

nut, an insert and a holder.

3. Place the brass nut in the metal mounting device which is attached to the front of the machine.

4. Place one of the cut samples FACE DOWN in this nut.

5. Place one of the cut pieces of foam on top of this sample.

6. Place the metal insert on top of this with the flat side down.

7. Screw the holder back onto this arrangement ensuring that the sample lies parallel, this will be

achieved if pressure is applied while screwing the holder back together. Note the spindles

supplied to test for abrasion are the shorter ones. Repeat this procedure for each abrading table.
