7 M# _% C x) n0 m1 {" }. ZWith immediate effect, cords having a cross sectional area of 1,0 mm² are not allowed for portable socket-outlets with VDE or VDE GS Mark. Tests performed by the VDE Institute have shown, that portable socket-outlets having cords of this cross sectional area always exceed the allowed temperature limits according to DIN VDE 0298-300. The VDE Institute has informed his customers about this fact by the following letter: 16:50 23.02.2009

This means, that e. g. a temperature rise test on portable socket-outlets according to DIN VDE 0620-1:04-2005 at a testing current of 20A is necessary irrespective of the cross sectional area. If for this product, a cord having a cross sectional area of 1,0 mm² is used, a temperature rise measurement directly on the cord is also involved.

For this reason it is no longer possible to certify products having a cross sectional area of 1,0 mm².( j; q" {: E: L# v! `' P
