Ferraris type meters/three-phase units: - 40 meters/units selected every 2 months. Static watt-hour meters: - for plants with a production higher than items per year, two samples, each one made up of 40 meters. - for plants with a production equal to or above 60,000 items per year, 40 meters selected every month. - for plants with a production below 60,000 items per year, 40 meters selected every 2 months. An entire packaged set of products ready for dispatch shall constitute the above samples. With the exception of static watt-hour meters, a further 5 meters/units, not yet sealed, shall be sampled in order to carry out mechanical tests. For plants with a production higher than items per year, at the beginning of the surveillance activity, the inspection visits will be carried out with a weekly frequency. After 4 inspections, if no points of non-compliances arise, the relevant frequency will be changed into a fortnightly one. Every time a non-compliance arises, the frequency will return to the one described before. Companies with non-continuous production may apply an on-call inspection procedure (see point 4 below) Tests to carry out and procedures a) Ferraris type electric meters and integrated meter units IMQ shall carry out tests from 1 to 10 of the CEI EN 60514:1997 standard, or tests from 2 to 11 of the CEI 13-15:1997 standard on each sample comprising 40 or 80 meters/units. It will also carry out test 11, or test 12 respectively of the above standards (mechanical test), on 5 meters/units which have not been sealed yet.
