In order to be able to operate a measuring system for billing purposes, system operators in countries subject to the scope of the MID [2014/32 / EU] require an EU declaration of conformity. It certifies to the system operator that his new or refurbished measuring system is compliant with the legal requirements. All billable measuring systems from SICK are certified, among other things, according to the relevant MID modules B (EC type examination) and D (Quality assurance of the production process) by the National Metrology Institute of Germany (PTB). Depending on the system type, SICK offers initial verifications, repairs or re-verifications.
