3、ldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on
4、 that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopte
5、d 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.

8、etworking permitted without license from IHS -,-,- INTERNATIONAL STANDARD IS0 12302:1993(E) Plain bearings - Quality characteristics - Statistical process control (SPC) - 1 Scope This International Standard specifies for plain bearings (except thick-walled half-bearings) those quality char- acterist
9、ics in accordance with IS0 12301 which can be used to regulate and control a production process on the basis of statistical process control LSPC). It covers dimensional variables but does not take ac- count of attributes. 2 Normative reference The following standard contains provisions which, throug
10、h reference in this text, constitute provisions of this International Standard. At the time of publica- tion, the edition indicated was valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to in- vestigate the possibility of appl

IS0 12301: 1992, Plain bearings - Quality control techniques and inspection of geometrical and material quality characteristics. 3 Definitions For the p
12、urposes of this International Standard, the following definitions apply. 3.1 quality characteristic: Characteristic by means of which the quality of a plain bearing is assessed. 3.2 statistical process control (SPC): Control of quality characteristics of plain bearings during the production process
13、by means of statistical techniques in order to comply with quality requirements. 4 SPC methods The applied statistical methods used to achieve con- trol of a production process may be different and thus are to be agreed upon between the manufacturer and customer. 5 Selection of SPC quality character
14、istics Depending on the intended purpose, function, etc. of the plain bearings to be used, the manufacturer and customer shall select and stipulate the particular characteristics for SPC according to clause 6. NOTE 1 It should be noted that the designated charac- teristics in the matrix of clause 6
15、have been prepared as a guide. 6 Geometric quality characteristics The quality characteristics are classified into three groups. Following the order of the specified characteristics in accordance with IS0 12301, these quality character- istics are listed in the form of a matrix as: - preferred with
