Cancels and replaces the first edition (1974) and amendment 1 (1994). Specifies a method for the determination of the density of natural rubber latex concentrate between the temperatures of 5 °C und 40 °C. Intended for use when density determinations are used to calculate the mass of a measured volume of latex in locations where it is not practical to weigh directly or to control the temperature of the laboratory. The method is suitable for all latices from natural source, for synthetic latex and for compounded or prevulcanized latex as well as for artificial dispersion of rubber.
