The following method is used for plating abrasion resistance testing.

(5) Rotating plate abrasion test (Taber's abrasion resistance test)

This is a method of examining abrasion resistance of platings by using a device shown in [Fig.4], where a test specimen is mounted on a horizontally rotating disc and a load is applied on a pair of abrasive paper pasted abrasion wheels and the test specimen.

●Abrasive paper

Abrasive paper CC as defined in JIS R6252 or WA #240~#600 is to be used.

●Test specimen

A 120mm diameter circular disc is to be the standard. A 6mm diameter hole is bored in the center.

●Determination by change in the mass

Calculated with the following formula.

As discussed so far, there are following abrasion resistance testing methods: 1. Sand-falling abrasion resistance test, 2.Spray abrasion resistance test, 3. Reciprocation motion abrasion resistance test, Rotating plate abrasion resistance test (Taber's abrasion resistance test), and 5. Twin disc drive abrasion tester (Amsler type abrasion testing). As to which testing method is to be used will be determined by the involved parties.
