Plastics — Methods for determining the density of non-cellular plastics — Part 2: Density gradient c...
This document specifies a gradient column method for the determination of the density of non-cellular moulded or extruded plastics or pellets in void-free form. Density gradient columns are columns containing a mixture of two liquids, the density in the column increasing uniformly from top to bottom.
NOTE Density is frequently used to follow variations in physical structure or composition…
Plastics — Evaluation of the action of microorganisms
This document specifies methods for determining the deterioration of plastics due to the action of fungi and bacteria and soil microorganisms. The aim is not to determine the biodegradability of plastics or the deterioration of natural fibre composites.
The type and extent of deterioration can be determined by
a) visual examination and/or
b) changes in mass and/or
c) changes in other…
