EN 13900-6:2012 (E) 4 1 Scope This European Standard specifies a method assessing the degree of dispersion of colorants1) and/or extenders in a thermoplastic polymer.
The method is suitable for testing colorants and/or extenders in the form of concentrates or compounds in all polymers used for extrusion processes. NOTE Defects like gels, black specks, holes in the test film etc. are not in the scope of this standard. The film test result determined according to this method is valid only for the equipment, conditions and test polymer being used. The use of test conditions differing from those specified might give different results. The preparation methods of concentrates or compounds are not specified in this standard. The results obtained for individual colorants and/or extenders are therefore comparable only when the same conditions of preparation for concentrates or compounds and a comparable detection system are used. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 speck defect caused by agglomerates, aggregates and primary particles of the colorant and/or extender, impurities of basic test polymer
2.2 primary particle of the colorant smallest single unit detectable by physical methods
Note 1 to entry: Suitable physical methods are, for example, optical and electron microscopy. 2.3 aggregate particle comprising strongly bonded or fused particles where the resulting external surface area may be significantly smaller than the sum of calculated surface areas of the individual components Note 1 to entry: The forces holding an aggregate together are strong forces, for example, covalent bonds, or those resulting from sintering or complex physical entanglement. Note 2 to entry: Aggregates are also termed secondary particles and the original source particles are termed primary particles. [SOURCE: ISO/TS 27687:2008, 3.3] 2.4 agglomerate collection of weekly bound particles or aggregates or mixtures of the two where the resulting external surface area is similar to the sum of the surface areas of the individual components Note 1 to entry: The forces holding an agglomerate together are weak forces, for example van der Waals forces, or simple physical entanglement.
