" L0 S- A1 ]0 f- a0 |4 o% dOn 31.12.1999 the safety standard VDE 0619 which included the standards DIN 46319 for metric sizes and DIN 46320 for PG-sizes were withdrawn. On 01.01.2000 the new standard DIN EN 50262 came into force. The new standard uses the new metric sizes. In the transitional period - until 01.03.2001 - the PG-standard could still be used. For replacement PG-items may still be used. The ten sizes PG 7 / 9 / 11 / 13,5 / 16 / 21 / 29 / 36 / 42 and PG 48 were replaced by eight new metric sizes, i.e. M 12 / 16 / 20 / 25 / 32 / 40 / 50 and M 63. No direct conversion is possible!
