ISO 1141:2021 ファイバーロープ—ポリエステル— 3、4、8、および12ストランドロープ | ページ 2

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.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives ).

The main changes compared to the previous edition are as follows:

• the Scope, a statement specifying that the document does not cover all variations in strength or product performance has been added;
• Clause 3, the term"minimum breaking strength" has been added;
• Table 1, Table 2 and Table 3, the tolerances in linear density have been modified.

1 Scope
