Metrological Certificate (Pattern Approval Certificate)
The metrological certificate (Pattern Approval Certificate) confirms that measuring instruments comply with applicable metrological and technical requirements in regulated markets.
It is generally required for measuring instruments that are subject to state metrological control and registration procedures.
Approval is based on successful testing and subsequent registration in the relevant state register.
Certification may relate to:
- a single measuring instrument (one-time approval), or
- a device type (serial approval with defined validity period, typically up to five years).
When is a Metrological Certificate Required?
A metrological certificate may be required for measuring instruments such as:
- manometers
- temperature sensors
- speed measuring devices
- water meters
- flow meters
- other measuring instruments used in regulated applications
Particularly where measurement results are legally relevant or used in regulated sectors such as:
- industrial production
- environmental monitoring
- occupational safety
- medical applications
- energy and utilities
- commercial metering systems
The specific requirement depends on the product classification and the applicable regulatory framework.
Certification Procedure
The certification process may include:
- review of technical documentation
- laboratory testing
- evaluation of metrological characteristics
- assessment of calibration intervals
- review of software (if applicable)
- verification of tamper protection measures
Upon successful completion, the measuring instrument or device type is entered into the relevant register.
Important Aspects of Metrological Certification
- Typical validity period: up to 5 years (for type approval).
- Certification may apply to a single device or a device series.
- Approved instruments must be marked in accordance with applicable regulations.
- Measuring instruments used in regulated applications must be calibrated prior to commissioning and periodically thereafter.
