The full cut and paste, it looks like the UK is lagging behind again, whilst Norway is leading the field: 
 Norway has a building code standard from 1 July 2011 shut-off devices are required in new electric stove installations (Norwegian standard NEK 400:2010 Electrical low voltage installations. Part 400-8-823 residential buildings). 
 Kirsi Rajaniemi, EU Fire Safety Network, Finland , in his letter to Commission on developing an EU Safety Standards, expressed his concern over the lack off a standard for such devises. 
 Great Britain creating a new British Standard BS EN 50615, &ldquo;Tests on devices for fire prevention and suppression for hobs (cooktop) fires&rdquo;. No more details available at the present time. 
 The EU has a Draft proposal for a new EU standard CLC/TC 61(SEC)1949 Draft prEN 50XXX &ldquo;Tests on devices for fire detection and suppression for hobs (cooktops)&rdquo; Chaired by Fabio Gargantini. We are committee members and part designers of this new standard. It has been sent to each European country for comment. 
 The London Fire Brigade, Community Safety Research & Policy Team, have the following observations regarding this standard: 
 &ldquo;We believe fires on or around cooktops present such a significant hazard that the occupier should be alerted, the power supply automatically isolated and that the occupier should leave the premises
