When it comes to technical innovations, safety, hygiene and quality standards make sense only if all can be reasonably implemented in the field. Certification by independent bodies enables product manufacturers, specialist companies, utility companies and experts to demonstrate to their customers and market partners that their products, processes, systems and services are state of the art. Certification always includes testing and assessment of the product, assessment of the results and, finally, the confirmation and monitoring of conformity. Neutrality, quality and reliability always have top priority in certification.
