Normas unificadas para a Europa – HBM vai à frente (em inglês)
In Europe, there are regulations and directives governing methods of measurement and test procedures for measuring instruments. MID (Measuring Instruments Directive 2004/22/EC) is a directive that assists technical harmonization and standardization. HBM take this directive as its basis in product planning.
1) Measuring Instrument Directive 2004/22/EC (MID)
Directive 2004/22/EC of the European Parliament and Council dated March 31, 2004 concerning measuring instruments. An example for automatic weighing instruments as per Annex MI 006 is shown.
2) MID conformity assessment procedures for (MI006)
The conformity procedures shown are applicable to the MID (MI006), in accordance with the new concept of the European Commission, better known as the Blue Guide. Modules B + F, B + D and H 1 are relevant to automatic weighing instruments.
3) MID conformity assessment procedures
The B + F combination is usually preferred by manufacturers who play a restricted role. In Germany, the weights and measures offi ce is also involved in the statement of conformity.
With the B + D combination, the manufacturers themselves are able to validate the statement of conformity. In Germany, the statement of conformity used to be known colloquially as “verification”.
4) Type examination (Module B)
Currently about 90 % of all conformity assessment procedures are performed with the aid of module B (type examination). The main emphasis here is on procedures 1 and 2.
Components that have already been examined are useful for the required type examination. For example, digital load cells that in addition to EN 45001; OIML R60, are also examined for EMC requirements as per OIML D11/2004 and for software-related requirements, as per Welmec guide 7.2*.
