Foreword(前言)
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.
ISO(国际标准化组织)是由国家标准机构(ISO 成员机构)组成的世界性联合会。国际标
准的制定工作通常通过 ISO 技术委员会进行。对已设立技术委员会的主题感兴趣的每个成员
机构均有权派代表参加该委员会。与国际标准化组织保持联系的政府和非政府国际组织也参
加了这项工作。ISO 与国际电工委员会(IEC)在所有电工标准化问题上密切合作。
