Plastics - Determination of ash - Part 3 : Unplasticized cellulose acetate

PUBLISH DATE 1984
ISO 3451-3:1984

Specifies a method for the determination of the ash unplasticized cellulose acetate, free of additives, fillers, dyes or other materials, which may affect the result.

Ignition of a test portion and calcination in a muffle furnace maintained at 575 °C or 850 °C (as agreed). Higher temperatures such as 850 °C will convert carbonates to the oxides and thus give lower values.

The general instructions in ISO 3451/1 shall be followed.
