Rudolf Heinz, the project manager of ComplianTV’s product lab, said that Samsung was “meeting the letter of the law but not the spirit of the law”.
There is no suggestion that Samsung behaved illegally or improperly, however some campaigners think tests could be more rigorous.
Jack Hunter, a spokesman for environmental watchdog the European Environmental Bureau, which is funded by European governments, told the Guardian that there would be many angry customers if TVs were proved to be deception during tests.
“There’s more than a whiff of diesel fumes coming out of this, with officials finding gadgets that recognise test conditions and alter their behaviour,” Hunter said.
