Standard describes two methods (A and B), Method A Method B faster than, the sample for testing single pigment, the plurality of test samples, Method B better, particularly for unknown samples achromatic pigment. Note: When the general method applicable to specified pigment, the pigment product standards indicate that the method, and indicate the characteristics of the pigment to be done any detailed changes. Only when the general approach does not apply to a particular pigment, stipulates that a special method to compare the reducing power of white pigments.

This Part replaces GB/T 5211.16-1988 "relatively achromatic white pigment force." This part of the previous version GB/T 5211.16-1988 main technical differences are as follows. --- Front line version is equivalent to using ISO 787-17. 1973; --- Increased step "polishing by hand or spatula mixing white and blue pigment paste," the. This part is proposed by the China Petroleum and Chemical Industry Association. This part of the National Standardization Technical Committee and is under the jurisdiction of paints and pigments. This part mainly drafted by. China National Chemical Construction Corporation, Changzhou coating Chemical Research Institute. The main drafters of this section. Shen Su River. This section was first released in 1988, this is the first revision. This part of the National Standardization Technical Committee and paint pigments responsible for the interpretation. GB/T 5211.16-2007/ISO 787-17.2002 Comparison of tinting strength of white pigments1 ScopeThis section provides general test methods compare with the same type of white pigments agreed achromatic color capabilities. Standard describes two methods (A and B), faster than the method A method B, for the test samples of a single color; for a plurality of samples Test Method B is better, particularly for unknown samples achromatic pigment force. Note. The general method is applicable to specify a pigment in the pigment product standard should be noted that the present method, and indicate any due to the characteristics of the pigment and the need to do Detailed changes. Only when this general method does not apply to a specific pigment, only the provisions of a special method to compare the tinting strength of white pigments.2 Normative referencesThe following documents contain provisions which, through reference in this text, constitute provisions of this part.
