ISO 12384:2010 Aerospace —航空機の電力特性を測定するためのデジタル機器の要件 | 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 12384 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee SC 1, Aerospace electrical requirements.

ISO 12384 is closely allied with ISO 1540 and references from one to the other are freely used, particularly from ISO 12384 to ISO 1540. The proper use of this International Standard through referencing the applicable specific digital measurement methods should simplify the preparation of specifications and help to expedite the purchase and acceptance of the digital measuring equipment.

Introduction

Various types of digital measuring equipment for electrical power characteristics are applied to the aircraft electrical system. There is no International Standard for digital measuring equipment for electrical power characteristics in the aerospace industry. The purpose of this International Standard is to explain, establish and standardize specific methods for digital measurements of the aircraft electrical system. The intended use of this International Standard is to define how to measure parameters of electrical characteristics in aircraft electrical power systems. The specific measurement methods are included here, while the terminology and general methods of digital measurement and signal processing are also presented. The requirements of digital measuring equipment are verified by testing of the aircraft electrical system.

1 Scope

This International Standard specifies the requirements for digital measuring methods and digital measuring equipment for aircraft electrical power characteristics, including accuracy, algorithms and digital measuring equipment. The measuring equipment should be applied mainly for the use of laboratory or rig tests.

This International Standard can be applied to digital measuring equipment which is involved in the measurement of power electrical characteristics of the power supply system, power distributing systems and the utilization of equipment in aircrafts.
