Since 01 January 2015, the new Measurement and Verification Act has been in force. This no longer permits any initial verification for dial thermometers. If an initial verification is required to place the measuring instrument on the market for the first time, this requirement will be met through a conformity assessment procedure. The conformity assessment of a measuring instrument basically replaces the former initial verification. In place of the appropriate office of weights and measures, a conformity assessment body, selected by the manufacturer, (which can still be an office of weights and measures) confirms the conformity of a measuring instrument with the valid legal requirements through issuing a certificate of conformity. On the basis of this, the manufacturer of the measuring instrument prepares a written declaration of conformity for the measuring instrument. Once the validity expires - provided the conditions are met - as is normal, a (re)verification is required so that the measuring instrument can once more be used in commercial and/or official operation. Both the conformity certificate and also the verification certificate carry the same weight - in accordance with the guidelines of the New Approach 2004/22/EC and 2009/23/EC and also in accordance with the Measurement and Verification Act (MessEG) in conjunction with the Measurement and Verification Ordinance (MessEV) supported by it.
