Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

International Standard ISO 3451‑4 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 5, Physical-chemical properties.

This second edition cancels and replaces the first edition (ISO 3451‑4:1986), which has been technically revised.

ISO 3451 consists of the following parts, under the general title Plastics — Determination of ash:

— Part 1: General methods
— Part 2: Poly(alkylene terephthalate) materials
— Part 3: Unplasticized cellulose acetate
— Part 4: Polyamides
— Part 5: Poly(vinyl chloride)

WARNING — This part of ISO 3451 may involve hazardous chemicals, materials and operations. This part of ISO 3451 does not purport to address the safety problems associated with its use. It is the responsibility of the user to establish proper safety and health practices and determine the applicability of regulatory limitations prior to use.
