Software in measuring instruments

Purpose

Measuring instruments used in sales to private individuals in Europe must meet EU requirements. It is important that the measuring instruments are quality assured and provide reliable measurement results. The requirements are described in the Measuring Instruments Directive, 2014/32 / EU (MID). The MID includes various types of measuring instruments such as water meters, gas meters, electricity meters, heat meters, measurement systems for liquids other than water (such as petroleum pumps), automatic weighing instruments and taximeters. For non-automatic weighing instruments, there is a separate directive, 2014/31/EU (NAWI).

An approved test of a measuring instrument and the preparation of a certificate according to MID, opens up a market across the EU to the manufacturer. The approval procedure includes an evaluation of the software according to WELMEC Guide 7.2, or WELMEC Guide 2.3 (for non-automatic weighing instruments).

An approved test of a measuring instrument and the preparation of a certificate according to MID, opens up a market across the EU to the manufacturer. A RISE certificate is sufficient for marketing in all EU countries.

An accredited software test report can also be used by many national authorities outside Europé.

Method

The software evaluation at RISE follows the guidelines in WELMEC Guide 7.2, OIML D31 and OIML R117. We work with design reviews, document reviews and functional tests. Long-term storage of measurement data, transfer of data, separation of the various parts of the software and download of legally relevant software are specially examined.

For non-automatic scales, the RISE follows the guidelines in WELMEC Guide 7.5. The protection of the software, the interfaces of the software and the identification of the software are specially examined. We work with design reviews, document reviews and functional tests.

RISE reviews, according to Welmec Guide 7.6,  that the risk analysis for the measuring instrument deals with protective assets, consequences of a fault, threats, attack vectors and techniques for reducing the risks. We work with design reviews and document Reviews.

Deliveries

The result of the RISE evaluation of software in measuring instruments or risk analysis assessment, is reported in a written report. The reports are part of the documentation needed to be able to issue a MID certificate for the measuring instrument.
