ASTM D2698 – Standard Test Method for Determination of the Pigment Content of Solvent-Reducible Paints by High-Speed Centrifuging
Description:
Significance and Use
3.1 This test method describes a rapid method for separating pigment from solvent-reducible paints.
3.2 This test method is used by paint producers and consumers for product acceptance and process control.
Scope
1.1 This test method covers the separation of pigment from solvent-reducible paints and the calculation of the percent pigment from the results of nonvolatile determinations on the total paint and the separated vehicle.
Note 1: This test method has been proven to be applicable to most solvent-reducible paints, the exception being those paints containing severely bleeding pigments or pigments such as carbon black that are very difficult or impossible to centrifuge.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
