With 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 $ e$ f! L* j2 }3 K1 S5 e2 O* I 2 h' K4 I$ b1 {$ k$ gFor 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. , h0 s* U- ^3 C2 i) Q + B9 M7 N7 v0 tTherefore it is necessary, to supplement the testing requirements according to the safety-relevant gaps found in the standard. : U* y# q1 L* O# e5 R8 O 9 Y3 ~( p% @0 I8 x* x$ w7 t& o* `& dThis 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. # E- ~4 E5 i& I8 O% a" p0 Q, m- T
Based on the tests performed so far on 1,0 mm² cords the allowed temperature limits according to DIN VDE 0298-300 (VDE 0298 Part 300):2004 tables 4A or 4B are always exceeded. For this reason it is no longer possible to certify products having a cross sectional area of 1,0 mm². Q- k6 K( Y$ g4 Z; g |7 n, P x, [& z) G! a- f5 N; V$ o
The current marks approvals will be adjusted, i. e. the cross sectional area of 1,0 mm² will be deleted from the certificates.% c7 f& u7 d0 C

Hence from now on with 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. This fact will be published on our homepage in the internet. 4 n5 W!
