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.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, 3.

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.

Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

International Standard ISO 4714 was prepared by Technical Committee ISO/TC 87, Cork.

This second edition cancels and revises the first edition (ISO 4714:1986), which has been technically revised. The classification of composition cork and the behaviour in boiling hydrochloric acid have been removed.

Introduction

Composition cork is a material with many different compositions and applications.

This International Standard gives the specifications required to provide its minimum characterization.

Performance requirements related to an intended use are specified in relevant International Standards.

Composition cork of low thickness may be obtained as such by direct compression or may be obtained either by reslicing blocks or by unwinding and cutting cylindrical rolls.

1 Scope

This International Standard establishes the minimum requirements for agglomerated composition cork in the sheet form and specifies the requirements for sampling, packaging and marking.
