标准简介
Gives a method for the qualitative evaluation of the tendency of some colouring materials to "bleed off" or to migrate from a plastic material into other materials, if they are in close contact with each other. To compare the properties of different colorants, they should be compounded with a given plastic in a suitable standardized formulation.
