Legal Metrology in Germany

• Basis
• European Directives
• National Law on Metrology and Verification
• Fields of application
• Commercial transactions
• Official transactions
• Environment
• Labour
• Health

4
Legislation for Metrology

• Regulation
• National Law
• Metrology and Verification Act
• Units of Measurement Act
• Ordinance
• Metrology and Verification
• Pre-packages
• Fees

• Responsible Body
• Parliament
• Federal Ministry

5
Enforcement of legal metrology today
Responsible Body
Main tasks

• Type approval
• Calibration of standards
• Consultancy for the authorities

PTB
Initial verification Periodic re-verification Mark
et surveillance Approval of testing laboratories
Verification offices
Approved testing laboratories
Initial verification and subsequent
verification (electricity, gas, water, heat)

Political, economic and technical developments

• Measuring Instruments Directive 2004/22/EEC (MID)
• Liberalization of the markets (energy)
• Private bodies for testing and assessment of
  instruments
• Software-controlled instruments
• Measuring data transfer in in open systems
• Remote displays without access to the consumer
• Measuring systems with exchangeable components

7
Principles of the Measuring Instruments Directive
2004/22/EC (MID)

• Free movement of measuring instruments
• Requirements up to placing on the market
• Essential requirements for measuring instruments
• Presumption of conformity for compliance with
  harmonised EN or OIML-IR
• Conformity assessment procedures
• Notified bodies

8
Instruments covered by MID

• Water meters
• Gas meters and volume conversion devices
• Active electrical energy meters
• Heat meters
• Measuring systems for liquids other than water
• Automatic weighing instruments
• Taximeters
• Material measures
• Dimensional measuring instruments
• Exhaust gas analysers

9
The MID does not prescribe

• Legal metrological control
• Legal status of the notified bodies
• Requirements for instruments after putting into
  use
• Maximum permissible error in service
• Subsequent verification
• Period of validity for conformity assessment
• Fees

Subject to national legal control
10
Instruments subject to legal control

• European Law
• All instruments covered by MID
• Non-automatic weighing instruments (NAWI)
• German Law (Examples)
• Electricity meters for U lt 123 kV
• Instruments for speed control
• Breath analysers
• Sound level meters
• Radiation protection measuring instruments

Legal frame in Germany
4 Categories of regulations as from 30 October
2006

• 1) Old Approach - Directives (1971 1986)
• 2) Directive on Non-automatic weighing
• instruments (1990)
• 3) MID Instruments (2006)

4) German Law on Metrology and Verification
(2006)
14
German legislation takes account of

• Complex measuring systems in open networks
• Software requirements and testing of software
• Distinction of measuring instrument, measuring
  system, sub-assembly and peripheral equipment
• Measuring instruments and measuring systems with
  separate displays
• Correct measurements not only measuring
  instruments

15
National and EC requirements harmonized

• MID-conformity assessment procedures also
  applicable to devices subject to national legal
  control
• MID-conformity assessment by Notified Bodies (NB)
• National conformity assessment by Conformity
  assessment Body (CAB)
• Requirements for CAB and NB equivalent

16
Privatisation of conformity assessment

• Private Notified Bodies (NAWI and MID) possible
• Private CABs (national) possible
• Stronger involvement of private bodies for
  subsequent verification, e.g. weighing
  instruments
• Private bodies shall be independent from
  development, production and repair of the
  instruments

17
Measures after putting into use

• Periodical subsequent verification to ensure
  durability
• Subsequent verification for all instruments
• MPE in service 2 x MPE for initial verification
• Sampling procedures for re-verification possible
• Metrological surveillance

18
Metrological surveillance

• Obligation for users to notify their instruments
• Metrological surveillance under the
  responsibility of the verification authorities
• a) Market surveillance of measuring instruments
  after placing on the market
• b) Surveillance of the users of measuring
  instruments
• c) Surveillance of private bodies

Effects on the verification authorities

• Decreasing number of initial verifications as a
  consequence of the MID
• Decreasing number of re-verifications as a
  national political consequence
• Considerable loss of fees and staff cuts
• Strengthening of market surveillance
• Surveillance of private bodies

21
Effects on PTB

• Role as Notified Body for the MID-modules B, D
  and H1
• Type examinations and design examinations (B, H1)
• Approval and surveillance of QM-systems (D, H1)
• Competition with NB in other European countries
• Competition with national bodies (if there are
  candidates)
• PTB designated as co-ordinator of national bodies

22
Transitional period

• Previous national approvals valid until
  30.10.2016
• National initial verifications valid until
  30.10.2016
• EEC-approvals are valid according to validity of
  approval
• EEC-initial verifications valid until expiring
  date
• Amendments of approvals (national) until
  30.10.2016
• Re-verifications possible for an unlimited period

23
Harmonization of MID-application

• Co-operation with the EU Commission
• Determination of the normative documents (OIML
  IR)
• Harmonization of notified bodies
• Information exchange concerning market
  surveillance
• Elaboration of WELMEC-guidelines endorsed by the
  EU Commission
