Directive Implementation (2009/23/EC)

Terms of Reference:
To consider and provide guidance on Directive 2009/23/EC, and Directive 2004/22/EC with regard to Automatic Weighing Instruments (AWIs) and Multidimensional instruments, to facilitate all aspects of implementation apart from inspection, enforcement and reverification.
To consider and provide guidance on weights, Directive (71/317/EEC, 74/148/EEC).
To similarly support the WELMEC cooperation for those AWIs falling outside of Directive 2004/22/EC.

General Aspects of Legal Metrology

• how uncertainty is considered in legal metrology
• the use of accuracy classes in connection to the purpose of legal requirements
• the acceptable "failure rate" for different purposes and to work for harmonisation on these matters where needed taking into account ongoing discussions and development in OIML.

Metrological Supervision

Terms of Reference:

• Establish confidence of all stakeholders in legal metrology provisions, by supporting the co-operation between WELMEC Members, to promote equivalent, effective and sufficient levels of metrological supervision across the EU.
• Promote and organise the exchange of information and guidance on metrological supervision matters, including market surveillance and field inspection, between WELMEC Members.
• Provide the means for dialogue with representatives of consumers, trade, industry and the commission.

Units of measurement.
Regulation on market surveillance to be included in the work programme.

Prepackages

Terms of Reference:

1. Come to a uniform application of the directives and regulations relating to:
   • prepackaged products;
   • particular sizes,
   • packaging
   • sampling.
2. Establish a platform for exchange of information on all matters relating to the sale of prepacked¹ products sold by quantity (either under European or national legislation);
3. As experts, give advice to the Commission on aspects to be considered in new and existing legislation relating to prepackages;
4. Give opinions to Competent Departments; Packers and Importers on various practical issues relating to prepackages and other prepacked products.
5. Produce practical guidance on checking products in the marketplace for compliance to European legislation on prepacked product.

Measuring Instruments Directive

The following terms of reference have been adopted for WELMEC WG 8 during the 20th WELMEC Committee ( Casta Papiernicka 13 – 14 May 2004) :

General application of MID , except market surveillance (scope of WG 5) and exchange of information (ad hoc group), in particular with a view to establishing guidance documents on :

• conformity assessment modules,
• appointment (criteria) of notified bodies,
• operation of notified bodies.

In addition , WG 8 will take into account :

• the definitions of MID and OIML (clarification where differences appear between MID and OIML vocabulary),
• the organisation of MID implementation workshops.

Reminder

The here under specific aspects in relation with MID are not in the scope of WG 8 but are dealt with by the following WELMEC WGs:

WG 2 : automatic weighing machines

WG 4 : uncertainties of measurements, accuracy classes

WG 5 : market surveillance

WG 7 : software

WG 10 : measuring systems for liquids other than water

WG 11 : measuring instruments for utilities

Ad hoc group : exchange of information

R117 Measuring systems for liquids other than water
R105 Direct mass flow measuring systems for quantities of liquids
R81 Dynamic measuring devices and systems for cryogenic liquids
The (European) Measuring Instruments Directive (MID)

Utility Meters

Support of a harmonised European approach towards legal metrology issues with regard to utility meters, in particular:

1. Support of the implementation, coherent application and interpretation of Directive 2004/22/EC (MID)
2. Support of the introduction of new metering techniques under the scope of the MID
3. Development of proposals for matters in respect to scope and application area of MID
