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, Part 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 part of ISO/DIS 23814 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

International Standard ISO/DIS 23814 was prepared by Technical Committee ISO/TC96, Cranes, Subcommittee SC5, Use, operation and maintenance.

Introduction

0.1 General

0.1.1 The objective of this International Standard is to achieve uniform competency standards for work involving crane inspectors.

0.1.2 There may be in some countries additional authority requirements for the competency of crane insepctors which cannot be ignored.

Typical clauses affected by this are those regarding accreditation (certification).

Secretary's note. Clause 0.1.2 is proposed by the secretary in order to avoid possible conflicts between the requirements in this standard and maybe existing mandatory authority regulations in some countries. When implementing this standard individual ISO member bodies may be forced to refer to existing National Regulations as well.
