According to London Fire Brigade, they are calling for manufacturers to use metal rather than cheaper plastic to make the backs of fridges in order to protect flammable polyurethane insulation from components that could cause a blaze. They added US fridges have metal back while the EU has not r

It's not quite 'resistance', it's more a matter of different priorities. US safety standards major on protection against fire because they were originated by the insurance industry (Underwriters Laboratory) for obvious financial reasons, while European safety standards major on prevention of el

John, thanks for background info! LFB said one fire every day in London is caused by white goods. It is a horrible figure! Grenfell Tower Fire is a bit different from previous ones and had another risk of non-approved insulation and cladding tiles on the outer wall of building. It is still u

Here's a slightly dated but popular US magazine article with a table near the end that supports John's closing thought about rarity of fridge fires compared to tumble-dryer fires (1:9 ratio). http://www.consumerreports.org/cro/magazine/2012/03/appliance-fires-is-your-home-safe/index.htm Cheers,

Hi Adam, The info supplied is interesting!  Yes, it aligns with John’s thought.  However, the recalled units are quite different – 5,200 vs 1.2 m.  In the UK, there are a few million recalls of clothes dryers in last few years – that is quite different from US data.  Is there similar data of

Here's another good UK data source for incidents, not recalls: https://www.gov.uk/government/statistical-data-sets/fire-statistics-data-tables The "Domestic appliance fires dataset" file near the bottom can be parsed by appliance type. Cheers, Adam adam.di...@ieee.org On Sun, Jun 25, 2017 at

Adam, It is a good statistics! Actually US now also adopts UL EN 60335-2-24 as their safety standard.  Does UL have deviation for US in this standard as suggested by John? Thanks and regards, Scott From: Adam Dixon Reply-To: Adam Dixon Date: Sunday, 25 June 2017 at 7:52 PM To

The United States has significant national differences. Many U.S. national standards have very strict flammability requirement for larger areas of materials used indoors. The basic requirement applies when you have a piece of material longer than 6 feet (2 meters) or greater than 10 square feet

Hi Ted, Very appreciate your useful information! It tells me why I could not find it in the product specific safety requirement in UL 250 & UL 60335-2-14. According to testing laboratories, they claim the plastic back, HIPS is allowed but must meet fire retardant UL-94 5VA rating, otherwise meta
