0 c5 c% i, C9 l ^. k# i5 A5 wWith 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

For portable socket-outlets – consisting of socket-outlet, cord and plug – the temperature rise test according to DIN VDE 0620-1:04-2005, differing from table 20, has to be applied at a testing current of 20A on all parts of the product (socket-outlet, cord and plug) – irrespective of the cross sectional area, see also EK1 decision No. 393-08.$ u0 G& H3 k3 {.

Therefore it is necessary, to supplement the testing requirements according to the safety-relevant gaps found in the standard.* O+ o7 O; @, b2 }
3 Y. M, ^1 a2 Q' Q p1 |8 JThis 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.
