The well-known N-mark is a certification mark based on Nemko’s own testing or results performed by labratories according to multi-national or bi- lateral agreement or by otherwise Nemko accepted labratories including all authorized manufacturers. The mark signifies that Nemko has tested or certified the product according to national standards official safety regulations in Norway. (which in principle are aquivalent to those of the other European EU/EEA states) The N-mark is well-established among the consumers nationally, and on the international industrial markets. Consumer surveys show that 70% of the Norwegian population is familiar with the N-mark and its safety and quality. Followed by a product certificate, the N-mark also provides manufacturers and importers with an assurance that their product fulfills all technical demands relevant to Norway in particular and to Europe in general. Within the Nemko organization, we offer several optional marks and labels that provide further documentation of quality and safety in sales and marketing activities. Different product categories are subject to different safety demands. Consequently, our marks and labels differ accordingly
