1. IPFA categories
A measuring instrument must provide a high level of metrological protection so that all parties involved can have confidence in the measurement result. It must be designed and manufactured to a high standard of metrological technology and measurement data security.
The solutions adopted with regard to requirements take into account the intended use of the instrument and any foreseeable misuse.
The different IPFA categories are :
instruments delivering discrete quantities of product, by successive weighing, and whose mass has been predetermined; these are weight dosers (or bagging machines) (§ 3

1. European regulations
Depending on their intended use, automatic weighing instruments (AWIs) may be subject to government control at the design, construction, installation and use stages.
The new approach to harmonizing national legislation for AFPIs is similar to that for NAWIs. Its aim is to lay down essential metrological and performance requirements, to guarantee effective protection...
