Overview
EN 837-1:1996 is the European standard for Bourdon tube pressure gauges, titled "Pressure gauges - Part 1: Bourdon tube pressure gauges - Dimensions, metrology, requirements and testing." It specifies requirements for indicating pressure gauges, vacuum gauges and combined (compound) gauges with Bourdon tubes (designated B) in circular, spiral or coiled forms. The scope covers nominal sizes from 40 to 250 and pressure ranges up to 1600 bar (gauge pressure). In this standard a reading of zero bar = atmospheric pressure.
Key topics and requirements
This standard sets out the main technical elements needed to ensure consistent design, measurement reliability and safety:
- Dimensions and mechanical design: standardized nominal sizes (40–250) and form factors (circular, spiral, coiled) to ensure interchangeability and fit with instrumentation panels and mounts.
- Metrology and calibration: requirements for measurement accuracy, traceability and calibration procedures to support reliable pressure indication.
- Performance and testing: defined tests and acceptance criteria for functional performance, repeatability and operational behavior under specified conditions.
- Construction and materials: guidance on materials and construction compatible with Bourdon tube mechanisms and intended service (vacuum, pressure, compound).
- Marking and documentation: minimum information to be marked on the gauge and provided with the product (e.g., range, units, nominal size).
- Safety and operational requirements: provisions to reduce risk from overpressure, leakage or mechanical failure during normal operation and testing.
(Note: the standard text should be consulted for exact test methods, limits and detailed clauses.)
Practical applications
EN 837-1 is used where accurate, durable mechanical pressure measurement is required:
- Industrial process control and manufacturing plants
- Hydraulic and pneumatic systems
- HVAC and building services instrumentation
- Laboratory and calibration environments for pressure measurement
- Petrochemical, power generation and water treatment facilities
By following EN 837-1, organizations ensure pressure gauges meet recognized dimensional, metrological and testing expectations for safety and interoperability.
Who uses this standard
- Gauge manufacturers - product design, production and quality control
- Calibration and test laboratories - metrology procedures and traceability
- Specifiers and procurement teams - purchasing compliant gauges
- Maintenance and instrumentation engineers - installation and replacement decisions
- Regulatory and conformity bodies - assessment and certification references
