Cricket lighters must comply to very strict safety standards. Basically each country has governmentally recognized test bodies that will certify products to insure that they comply to international safety standards like DIN, ISO and ASTM. The GS marking, "geprüfte Sicherheit", is a German safety certificate marking that shows that the lighter is tested and conforms with the lighter safety standard ISO9994.
We have the GS Marking for the CR Lighters for Europe. For more information, please refer to the document below: GS CRICKET 2010
