Scope
This standard specifies the method for determining the size and dispersion of pigments or carbon black particles and agglomerates in polyolefin pipes, fittings, and compound materials.
This standard applies to polyolefin pipes, fittings, and compound materials. When determining carbon black, this standard applies to polyolefin pipes, fittings, and compound materials with a carbon black mass fraction of less than 3%.
