ISO 176:2005
Plastics - Determination of loss of plasticizers - Activated carbon method
ISO 176:2005 specifies two empirical methods for the quantitative determination of the loss of mass from a plastic material under defined conditions of rime and temperature, in the presence of activated carbon. Method A -- The test specimens are in direct contact with the carbon; this method is particularly useful for materials that have to be tested at relatively low temperatures because they flow at higher temperatures. Method B -- The test specimens are placed in wire cages that prevent direct contact between the test specimens and the carbon. These methods apply, in particular, to the quantitative determination of the loss on heating of plasticizers from plasticized plastic materials, in which case it is generally assumed that no significant amounts of other volatile materials are present. They are empirical test methods, suitable only for a rather rapid comparison of the losses of plasticizers or, in general, of volatile compounds, from different plastics. ISO 176:2005 also applies to the comparison of different types of plasticizers; in this case standard compounds should be prepared, on the basis of a well characterized resin, with known ratios of resin to plasticizer.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.
The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
