There isn't, almost certainly, a single reason, and we must take care that evidence that standards need to change isn't swamped by a greater body of evidence of non-compliance.
For example, we recently had, in Britain, many tumble-dryer fires. The standard may allow a warning in the instructions to 'clean the filter regularly' but the filter should really not clog or there should be a warning light if it clogs *and* the machine should not run with it on. > -----Original Message----- > From: John Allen [mailto:john_e_al...@blueyonder.co.uk] > Sent: Sunday, May 22, 2016 11:11 PM > To: EMC-PSTC@LISTSERV.IEEE.ORG > Subject: Re: [PSES] fire safety test methods for different country standards > > Rich. > > Could it be that the scenarios which the standards committees envisage are not > "the real deal", OR that the products which cause the fires just don't comply > with > the standards? > > IMO (not IMHO on this occasion !) the latter may well be the actual case, > because, in opinion, the number of counterfeit products on the market > worldwide is > so great that they are the cause (they minimise the production costs by > "deleting" > the safety features (i.e. the features that ensure that fires don't occur) . > > The EU RAPEX system identifies thousands of such products, and I saw good > examples of those products at the Nov 2015 UK Electrical Safety First > conference > in London. > > FWIW, that's why I did not agree with Gert G's comment about the lack of > fires in > his experience (which I do not doubt) from 61010 products. > > But, then there is the problem that most people don't read the product > instructions > - mea culpa, as that could be said of me on many occasions.
