Type examination according to module B of oscillation-type densimeters
The conformity assessment body (sector 4) is responsible for fundamental questions concerning conformity assessments of domestically regulated measuring instruments. |
Oscillation-type densimeters for liquids require a conformity assessment for domestic verification. The type examination according to Module B required for this purpose can be carried out in PTB's Working Group 3.32.
The basis for the examination are the "Ermittelte Regeln und Erkenntnisse des Regelermittlungsausschusses nach § 46 des Mess- und Eichgesetzes" (as of November 15, 2021, page 1 and from page 144 ff). The test program with regard to measurement accuracy is based on the PTB requirements PTB-A13.6 and the DIN 15212 standard.
For your application for conformity assessment (Module B), please use the application form. We recommend that you arrange a consultation with us before submitting your application.
The software check is part of the conformity assessment procedure. The check takes place on the basis of WELMEC Guide 7.2. Software tests are carried out by the PTB working group 8.51 and are arranged by us. More information about the documentation of the software can be found here.
Further information:
The type examination is carried out according to MessEV module B. In addition, either Module D or Module F must be combined (Module G also, but unlikely, since individual testing). Here the conformity assessment body can advise you accordingly.
The full costs for a type examination is generally difficult to estimate in advance. It is charged in accordance with Besonderen Gebührenverordnung of the Physikalisch-Technische Bundesanstalt [PTBBGebV] and calculated according to the amount of work required for the examination, the preparation of the documents and the documentation of the approval.
