IEC 61076-2:2011 establishes uniform specifications and technical information for circular connectors. It should be used in conjunction with the generic specification IEC 61076-1:2006 for product requirements and with IEC 62197-1 for quality requirements as the basis for preparation of consistent detail product specifications for circular connectors. In the event of conflict between this sectional specification and the detail product specification, it is intended that the requirements of the detail product specification prevail. This second edition cancels and replaces the first edition of IEC 61076-2 (1998). This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition. This International Standard no longer includes the quality assessment procedures. As described in IEC 61076-1 and IEC 62197-1, a new document structure has been established. IEC 61076-2 has been revised to reflect this updated structure. Subclause 3.2, Systems of levels has been introduced. The subclause on IEC type designation has been removed. Clauses 4 Dimensional information and 5 Characteristics have been added. Some clauses and test groups have been rearranged. Test group HP has been added.
