EN 14469的这一部分规定了在白色颜料的重量浓度下,确定增塑聚氯乙烯(PVC-P)中白色颜料的相对着色强度的程序。为此,将白色颜料与炭黑颜料制剂一起并入碱性混合物A(参见EN 14469-1)中
This Part of EN 14469 specifies a procedure for determining the relative tinting strength of white pigments in plasticized polyvinyl chloride (PVC-P) at identical concentration of the white pigments by weight. To this end, the white pigments are incorporated into the basic mixture A (see EN 14469 -1) together with a carbon black pigment preparation.
