13、ostatic devices and associated materials for frequency control, selection and detection, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 61837-2 on 2011-07-01. This European Standard supersedes EN 61837-2:2000. In EN 61837-2:2011, types of enclosures are renamed to e
14、xpress their features in their names for better understanding. The relative comparison of new types with old ones is listed in Table. 1. New names of enclosures express configuration type, terminal lead numbers, sizes and arrangement of terminal pads. The details of definition are shown in Clause 3:
15、 Configuration of enclosures, and Clause 4: Designation of types. Enclosures in EN 61837-2:2011 are based on EN 61240. In EN 61837-2:2011, 27 enclosures are added to EN 61837-2:2000, as follows: QCC-12/1407A, DCC-2/1206A, QCC-10/9272A, DCC-4/9070A, DCC-2-8045B, DCC-6/7834B, DCC-6/7050A, QCC-10/7050A
