EN 472:1994

Overview

EN 472:1994 - Pressure gauges - Vocabulary is a European Standard published by CEN that defines the fundamental and general terms and definitions used for pressure gauges and pressure measurement. The standard provides a consistent vocabulary to be used in technical documents, specifications, metrology, and cross‑border communications. It was later adopted into national systems (for example as SIST EN 472:1996 in Slovenia).

Key topics

This vocabulary standard focuses on clear, consistent terminology rather than performance or design rules. Key technical topics and elements covered include:

• Definitions of core concepts in pressure measurement (general terms used for pressure and gauge measurements).
• Standardized names for pressure gauge components and functional parts (common language for documentation and drawings).
• Terminology for measurement relationships such as reference points and measurement conditions.
• Unit and symbol consistency as used in pressure metrology and related documentation.
• Emphasis on alignment with metrology and measurement vocabularies (ICS 17.100; 01.040.17).

Note: EN 472 sets the language and meaning for terms used in other standards dealing with pressure gauge design, testing and calibration; it does not prescribe performance limits or test methods.

Applications

EN 472 is practical and widely useful for professionals who need unambiguous language around pressure measurement:

• Manufacturers of pressure gauges and transducers - to ensure product documentation uses standardized terms.
• Calibration and testing laboratories - for consistent reporting and certificates.
• Design and engineering teams - to align specifications, drawings and procurement documents.
• Quality and compliance managers - to reduce ambiguity when implementing regulatory or contractual requirements.
• Standards writers and technical translators - to harmonize terminology across languages and national standards.
• Training and technical publications - as a reference glossary for courses and manuals.

Using EN 472 helps reduce misunderstandings in procurement, maintenance, certification and international trade by providing a common lexicon for pressure measurement.

Related standards

EN 472 is a vocabulary standard and is intended to be used together with other CEN and international standards that address:

• Pressure gauge design and construction
• Test methods and calibration procedures
• Performance and accuracy classes for measuring instruments

For full technical requirements, consult EN standards on pressure gauge performance, calibration and safety (refer to CEN catalogues or national standards bodies for specific document references).
