Since its release, due to progress in technology, many of the enclosures given in the standard
20、have become obsolete. Bearing this in mind, the following 12 enclosure types have been deleted from the third edition of lEC 60122-3. AA, AB, BC, BC/1, BF, BF/1, CX, CY, CY/1, CZ, DA, DC. Therefore, this new version (the fourth edition) contains the following 36 enclosure types ; CK, CM, CN, CP, DK,
