IEC EN 60051-8 Direct Acting Analog Electrical Measuring Devices and Accessories - Part 8: Special Requirements for Accessories

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 60051-8 testing. IEC EN 60051-8 applies to accessories defined in 60051 of IEC EN 1-3.1.20.

The uncertainty must not exceed the amount specified in IEC EN 60051 1 at all values ​​of the measurand up to and including the nominal value. Shunts and series resistors should be tested using direct current unless frequency is specified.

When the current received by the relevant meter is less than the rated current multiplied by the shunt class index and divided by 300, the current taken by the relevant meter can be neglected.

The accessory has been tested with its own device. There are no requirements regarding uncertainty limits for either component alone, and the class index is relevant in combination.

Accessories other than those provided with a non-locking key must be subjected to a continuous overload of 2% of rated value for a period of 120 hours. After cooling to the reference temperature, the accessory must meet the requirements for the accuracy class.

All parts of this standard are organized in the same format, and a standard relationship between subject and item number is maintained throughout these sections. This arrangement will help the reader of IEC EN 60051 to distinguish information about different types of instruments.
