12、es (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
13、, 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 IS
14、O/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
15、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.

BS ISO 21368:2005vIntroduction Adhesive bonding technology is widely used to fabricate many of the structures in the manufacturing industry, and in some companies it is the key feature to production. Such structures may range from microelectronic encapsulation to the struct
17、ure and reinforcement of aircraft wings and bridges. Adhesive bonding technology is attractive to industry because it allows flexibility in the selection of materials, product design and product manufacture through to final assembly. As such, adhesive bonding technology exerts a profound influence o
18、n the cost of fabrication and the quality of the product, thus allowing significant production savings and a competitive advantage in comparison with traditional methods of manufacture. It is important, therefore, to ensure that adhesive bonding technology is carried out in the most effective way an
19、d that appropriate control is exercised over all aspects of the operation. Within the ISO 9000 series of standards for quality systems, adhesive bonding technology is to be treated as a “special process” since bonds cannot be fully verified by subsequent inspection and testing of the product to ensu
20、re the required quality standards have been met. Quality cannot be inspected into a product, it has to be built in. Even the most extensive and sophisticated non-destructive testing does not improve the quality of bonds. For adhesively bonded structures to be effective and fit for purpose in service
21、, it is necessary to provide controls, from the design phase, through material selection, into fabrication and subsequent inspection. Poor design for adhesive bonding will create serious risks and costly difficulties in the workshop, on site or in service. Inadequate consideration of the materials t
22、o be bonded and the choice of adhesive may result in bonding problems such as lack of adhesion or inadequate gap-filling of the structure. Adhesive bonding procedures have to be correctly formulated and approved to avoid imperfections. There must be supervision to ensure that the specified quality w
23、ill be achieved. To ensure the quality of adhesively bonded structures, management needs to appreciate potential sources of trouble and to introduce appropriate quality procedures. BS ISO 21368:2005blank1Adhesives Guidelines for the fabrication of adhesively bonded structures and reporting procedure
24、s suitable for the risk evaluation of such structures 1 Scope This International Standard provides guidelines describing the adhesive bonding quality requirements suitable for use by manufacturers utilizing adhesive bonding as a means of fabrication. In particular, the guidelines define various appr
25、oaches to meeting quality requirements for fabrication and reporting procedures, both in workshops and on site. These guidelines aim to convey the importance of maintaining quality standards in fabrication and reporting procedures, keeping records and thus enabling documentation to provide the basis
26、 for risk evaluation of adhesively bonded structures in service and in use. These guidelines have been prepared such that: a) they are independent of the type of adhesively bonded structure; b) they are independent of adhesive manufacturers and suppliers product recommendations; c) they define the q
27、uality requirements for adhesive bonding in terms of fabrication and reporting procedures, both in workshops and on site; d) they may be used as the basis for risk evaluation of adhesively bonded structures in service and in use; e) they may be used as a basis for assessing a fabricators capability
28、to produce adhesively bonded structures fulfilling specified quality requirements when they are detailed in one or more of the following: a contract between the parties involved, an application standard, a regulatory statement. The guidelines contained within this International Standard may be adopt
29、ed in full or selectively chosen by the manufacturer to suit the structure concerned. The guidelines provide a flexible framework for the control of adhesive bonding activities in the following cases: Case 1 The provision of specific requirements for adhesive bonding in contracts which require the m
30、anufacturer to have a quality system other than ISO 9001. Case 2 The provision of specific requirements for adhesive bonding as guidance to a manufacturer developing a quality system. BS ISO 21368:20052 Case 3 The provision of specific requirements for references in application standards which uses
31、adhesive bonding as part of its requirements or in a contract between relevant parties. Case 4 The provision of a framework for fabrication and reporting procedures to a quality standard, suitable in particular as a basis for the risk evaluation of adhesively bonded structures. 2 Normative reference
