11、, Uncontrolled Copy, (c) BSI BS G 262:1998 ii BSI 05-1999 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 committe
12、es. 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 Inte
13、rnational Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The main task of a technical committee is to prepare International Standards, but in exceptional circumstances a technical committee may propose the publication of a Technical Report of one of the followi
14、ng types: type 1: when the required support cannot be obtained for the publication of an International Standard, despite repeated efforts; type 2: when the subject is still under technical development or where for any other reason there is the future but not immediate possibility of an agreement on
15、an International Standard; type 3: when a technical committee has collected data of a different kind from that which is normally published as an International Standard (“state of the art”, for example). Technical reports of types 1 and 2 are subject to review within three years of publication, to de
16、cide whether they can be transformed into International Standards. Technical reports of type 3 do not necessarily have to be reviewed until the data they provide are considered to be no longer valid or useful. Technical Report ISO/TR 224, which is a Technical Report of type 1, was prepared by Techni

In 1994, ISO/TC 20s resoluti
19、on 620 judged it appropriate to publish the results of the work as a Technical Report because of some comments outlining the difficulties of its application which may conflict with JAR-TSO. However, if an approval authority, an aircraft manufacturer, or an operator asks for information on the design
20、 and performances of an equipment item, any applicable restrictions, and its degree of compliance with ISO 7137 or with any other standard to be specified, we recommend that the equipment designer use this standard declaration form. The results of official certification procedures in member countrie
21、s cannot be judged in advance from the indications given in the declaration of design and performance. 1 Scope This Technical Report specifies the standard form to be used for a declaration of design and performance (DDP) for aircraft equipment. A DDP is the commitment of a manufacturer to deliver a
22、 product complying with the defined dimensions and performances, based on qualification tests carried out by the NSO (National Surveillance Organization), a major user or by the manufacturer himself. A DDP is not a compulsory procedure, it remains optional; its purpose is to avoid repeated qualifica
23、tion tests for each use. For a specific program, the DDP can be certified for the aircraft manufacturer or the NSO. This means that the commitments of the manufacturer were met when the aircraft was certified. The DDP is intended for components and equipment which do not relate to any national or in
24、ternational or aircraft manufacturer specification. If a normative document giving a full definition of a product exists, the dimensions, performances and qualification of the product in question must be in accordance with that document. 2 Normative references The following standards contain provisi
