So, apparently there is a British Standard for something to be officially dishwasher proof/safe.
EN 12875-4: 2006 - Mechanical Dishwashing of Utensils-Part 4 Rapid Test for Domestic Ceramic Articles.

I have found one supplier saying that their sublimation mugs meet this standard.

Wonder if other suppliers are going to put an official rating on their products too.

Out of interest Pisquee, what supplier states this?

How do you find their mugs though?

I used to use them regularly but found that the consistency was a huge problem.

I believe that is the same test that Listawood used. It was mentioned on the document obtained by a member of this forum (who shall remain nameless unless you read the thread in this link: http://www.dyesubforum.co.uk/vbforum/sh ... #post22454). I'm not sure that Listawood ever quoted the details of the test on their site, though (that may have had something to do with the test proving that Orca coated mugs were not quite as bad as they'd originally claimed).
