This International Standard specifies methods for the determination of components in plastics that can be extracted by hot organic liquids near their boiling points. For one special case, a so-called cold-extraction method is given in AnnexB.
The extractable components can be monomers, oligomers, polymers, plasticizers, stabilizers, etc. The kind and percentage of extractable matter influence the properties of plastics.
The recommended extraction liquid depends on the type of plastic and on the purpose of the determination (see Table1). The extracted amounts of special constituents are often not quantitative in the sense of analytical chemistry.
This International Standard does not apply to plastics that come into contact with food or drinking water. Special regulations for those plastics are established in many countries. In order to test plastics for compliance with these regulations, methods other than those given in this International Standard are used in most cases. The methods of this International Standard are not intended to be used for migration tests.
If this International Standard is used to test plastics other than those mentioned in Table1, the operating conditions is intended to be agreed upon by the interested parties.
