Important note : Users cannot be edited or removed once added to your Multi user PDF.Defines an atomic absorption spectrometric method for determining the copper content of rubbers. Applies to raw rubber and rubber products with copper contents over 1 ppm. Copper contents under this limit can be determined if suitable adjustments are made to the mass of thet test portion and/or the concentrations of the solutions. Using the standard additions method may lower the bottom limit of detection.
