Verification of tyre pressure gauges

The stability, grip, cornering behaviour and braking performance of a vehicle's tyres must be optimal to ensure maximum safety. In addition, sufficiently inflated tyres can reduce fuel consumption, which is important in view of rising fuel costs. To be sure that the tyre pressure is correct, it should be checked regularly. The gauges we use for this purpose, both analogue and digital, should be checked for errors related to drift, environment, power supply, addition of components to the output loop and other process changes.

What is

verification of tyre pression gauges

The verification of analogue pressure gauges is governed by the Order of 25 April 1995 regulating the metrological control of pressure gauges for public use for motor vehicle tyres in the phases of verification after repair or modification and periodic verification.

For its part, the verification of electronic pressure gauges is governed by Order ITC/3700/2006, of 22 November, which regulates the State metrological control of pressure gauges equipped, totally or partially, with electronic components, with or without predetermination devices, intended to measure the pressure of motor vehicle tyres.

Which equipment must be verified?

The State metrological control of pressure gauges refers to the in-service phase and includes both verification after repair or modification and periodic verification of the gauges.

Analogue: mechanical pressure gauges for public use for motor vehicle tyres, falling within the scope of the Order of the Ministry of Public Works and Town Planning of 28 December 1988.
Electronic: pressure gauges equipped totally or partially with electronic components and with or without presetting devices, intended to measure the pressure of motor vehicle tyres.

Apave is accredited by ENAC No. OC-I/271 to carry out periodic verification and after repair or modification of the following pressure gauges as in-service instruments:

Electronic pressure gauges intended to measure the tyre pressure of motor vehicles up to 20 bar.
Analogue pressure gauges for use by the public for motor vehicle tyres up to 20 bar

Verification of fuel, AdBlue and LPG dispensers

When users fill up at a service station, they need to be assured that the fuel pumps and other products, such as AdBlue or LPG, are in perfect condition and that the quantities they dispense are accurate and reliable. Evolving European standards for regulating pollutant emissions have boosted the development of engines that can run on alternative fuels to actively reduce exhaust gases and pollutants. LPG is a widespread alternative fuel, as is natural gas (CNG and LNG) or vegetable oil for trucks. On the other hand, all diesel trucks and light-duty vehicles manufactured since October 2006 are equipped with a catalytic reduction system using AdBlue, an aqueous solution that converts pollutants into water vapour.

Therefore, filling stations must be equipped with the appropriate pumps to dispense both conventional and new fuels and comply with the relevant standards, including the verification of the pumps.

Inspection of fire-fighting installations

In order to preserve safety and integrity of people and property, Apave realize fire fighting installations checking periodically to ensure the performance of your installations.

Inspection of oil installations

Industrialised countries accumulate oil reserves to be able to adjust supply in real time to fluctuating consumer demand. The storage of hydrocarbons also makes it possible to guard against international crises, or to preserve crude oil while waiting for its refining. Oil storage presents two major risks: fires and soil and groundwater pollution. Avoiding this pollution is a major challenge, for which Apave is involved in checking the condition of tanks and their degree of corrosion.
