ISO 24537:2007 マイクログラフィックス— 16mmおよび35mmマイクロフィルムに使用されるリールの寸法 | 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.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of technical committees is to prepare International Standards. 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 document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 24537 was prepared by Technical Committee ISO/TC 171, Document management applications, Subcommittee SC 2, Application issues.

Introduction

There is an increasing variety of equipment available to retrieve 16 mm and 35 mm roll microfilm. Some equipment uses conventional threading from the supply reel to the take-up reel in order to drive the microfilm. Other equipment uses automatic threading techniques with reels and an ISO approved cartridge.

This International Standard is intended to provide 16 mm and 35 mm reel dimensions which will allow compatibility with readers using conventional threading, and which can also be used for microfilm storage. If a 16 mm reel is to be used in a cartridge for use in automatic threading equipment, the requirements of ISO 7761 will apply. The requirements for camera spools are specified in ISO 6148.

1 Scope

This International Standard covers the essential dimensions of lightweight reels, made of plastic or metal, used for the storage and retrieval of processed 16 mm and 35 mm microfilm that is used in manually threaded equipment.

Reels intended for use in 16 mm automated retrieval systems are outside the scope of this International Standard. The dimensions of these reels are specified in ISO 7761.

Camera spools are also frequently used for storing processed microfilm. The dimensions of these spools are outside the scope of this International Standard, but they are specified in ISO 6148.
