Since there are many seals on the market, one should pay attention as buyers exactly to it, who assigns her and how its observance is controlled.
Test characters can be differentiated above all according to by whom they are assigned (by an independent place or by the manufacturer) and on which basis the examinations are accomplished (or particularly developed standards, e.g. DIN standards test bases).
Examples of test seals are:
No test character is the CE-indication. Hereby a manufacturer explains only that he keeps all relevant requirements from EEC guidelines for his product.
