Serviceability, Wear and Abrasion

Serviceability
Purpose of Serviceability Testing
Wear
Wear Index (W.I)
If wear index increases, abrasion resistance decreases and vice-versa

Abrasion:

1. Plane or flat abrasion: A flat area of material is abraded.
2. Edge abrasion: This kind of abrasion occurs at collars and folds.
3. Flex abrasion: In this case, rubbing is accompanied by flexing and bending.

Points to be consider before abrasion testing:

1. Condition of specimen
2. Choice of testing instrument
3. Choice of abrasive motion
4. Direction of abrasion
5. Choice of abradant
6. Backing the specimen
7. Cleanliness of the specimen instrument
8. Tension on the specimen
9. The pressure between abradant and specimen
10. The end point of the test
