TS 5588 EN 60051-1

TS 5588 EN 60051-1 is the standard that brings together the common definitions and general requirements for direct acting indicating analogue electrical-measuring instruments and their accessories. It establishes the shared technical language for this family of instruments and provides the general foundation used across the rest of the series, rather than focusing on one single measuring function only.

Shared concepts in analogue measurement instruments

In general technical terms, a direct acting indicating analogue instrument converts an electrical quantity into a pointer movement on a scale. In this product family, performance is understood through concepts such as indication, scale arrangement, zero position, accuracy, operating conditions and the influence of accessories. The scope of this part is centered on the definitions and general requirements common to all parts of the series, while more specific rules are handled in the relevant companion parts.

Why accessories are part of the subject

The mention of accessories in the title matters because the behavior of a measuring system depends not only on the main indicating instrument but also on the auxiliary parts used with it. Terminals, transducers, connection elements and similar accessories can affect the integrity and practical use of the measurement arrangement. This document provides the common framework and terminology that allow these elements to be understood as one technical family.

• Defines the shared terminology for direct acting analogue electrical-measuring instruments.
• Brings together the general requirements common to all parts of the series.
• Includes accessories used together with these instruments.
• Functions as a common technical basis rather than a standalone detailed test method standard.
