20、his part of IEC 807 is applicable to rectangular connectors designed for use in equipment for telecommunication, electronic data processing and in electronic equipment or devices employing similar techniques. This generic specification shall be used in conjunction with the relevant detail specificat
21、ion(s). Connectors designated especially for applications at frequencies exceeding 3MHz are not covered in this generic specification. The object of this part of IEC807 is to establish uniform specifications, test type requirements and quality assessment procedures for rectangular connectors and to
22、establish rules for the preparation of detail specifications for connectors of assessed quality. In the event of conflict between this generic specification and the detail specification, the requirements of the detail specifications shall prevail. 1.2 Normative references The following standards con

Quality assessment procedures 3.1 Primary stage of manufacture The primary stage of manufacture as defined in 8.5.2 of IEC QC001002 is the first process subsequ
48、ent to the manufacture of finished piece parts and sub-assemblies. A sub-assembly is defined as the permanent assembly of two or more parts. This primary stage of manufacture and all subsequent processes shall be carried out under the direct surveillance of the manufacturers approved Chief Inspector
49、. They may be carried out by sub-contractors providing that equivalent disciplines apply. 3.2 Structurally similar rectangular connectors Connectors having the same basic design, common contact sizes and the same contact surface finish are considered to be structurally similar components as defined in 8.5.3 of IECQC001002. They may have differences in other features, such as number of contacts, overall size, mounting, termination technique, etc., but they all shall be produced by the same manufacturing processes and methods.
