EUROLAB, together with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 60051-3 testing. IEC EN 60051-3 applies to direct-acting wattmeters and varmeters with analog display.

IEC EN 60051-3 also applies to:

• Non-replaceable accessories used with wattmeters and varmeters;
• A combination of instruments and accessories, provided adjustments have been made for the combination;
• Electrical measuring instruments with direct-acting indication, whose scale markings do not directly correspond to electrical input quantities, provided the relationship between them is known;
• Instruments and accessories with electronic devices in their measuring or auxiliary circuits.

IEC EN 60051-3 does not apply to:

• Special-purpose tools under their own IEC standards;
• Special purpose devices that fall under their own IEC standards when used as accessories.

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.
