GB/T 20167-2012 Physical test method of rare earth polishing powder—Determination of burnishing mass and scratch—Gravimetry
Abstract
This standard specifies the method of measuring the abrasive wear and scratch resistance of rare earth polishing powders using a double-sided polishing machine.
This standard is applicable to the measurement of abrasive wear and scratch resistance of rare earth polishing powders mainly based on cerium. The measurement ranges are: abrasive wear 0.05 mg/(cm2·min) to 0.25 mg/(cm2·min), and scratch resistance 0% to 100%.
