EN 12645:2014

The standard EN 12645:2014 is a European norm defining the metrological and technical requirements for tyre pressure gauges. In other words, inflators with this certification have passed tests guaranteeing high pressure-measuring accuracy and reliability when inflating tyres. Correctly inflated tyres are key to road safety and fuel economy, and this standard is what ensures the instruments meet strict accuracy requirements.

Who are certified inflators for?

Inflators certified to EN 12645:2014 are used above all where the highest accuracy and reliability of pressure measurement is required:

• Car and tyre services: professional inflation and pressure checks on customers' tyres.
• Filling stations: public air points need dependable instruments for drivers.
• Companies with their own fleet: for maintaining company vehicle tyres with an emphasis on accuracy.

Checking and calibrating inflators

For an inflator to keep the accuracy the standard requires, regular checking and calibration is necessary. Instruments should be checked at least once a year (more often with heavy use) at a specialist service or calibration laboratory. Regular calibration ensures the inflator continues to meet EN 12645:2014 and to deliver reliable pressure readings.
