ISO 6427:2025

This document specifies methods for the determination of components in plastics that can be extracted by hot organic liquids near their boiling points. It also specifies a special extraction method called cold-extraction. The extractable components can be monomers, oligomers, polymers, plasticizers, stabilizers, etc. The kind and percentage of extractable matter influence the properties of plastics. This document does not apply to plastics that come into contact with food or drinking water, because special regulations for those plastics are established in many countries. The methods of this document are not intended to be used for migration tests. If this document is used to test plastics other than those mentioned in Table 1, the operating conditions are intended to be agreed upon by the interested parties.
