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. Esch 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, govern-
mental 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 approval before their acceptance
as International Standards by the ISO Council. They are approved in
accordance with ISO procedures requiring at least 75 % approval by the
member bodies voting.
International Standard ISO 3451-5 was prepared by Technical Committee
ISO/TC 61, Plastics.
ISO 3451 consists of the following Parts, under the general title
Plastics - Determination of ash:
- Part i: General methods
- Part 2: Polyalkylene terephthalates
- Part 3: Unplasticized cellulose acetate
- Part 4: Polyamides
- Part 5: Po/y(vinyl chloride)
