CEN/TC 141 - Pressure gauges - Thermometers - Means of measuring and/or recording temperature in the cold chain
Standardization of basic and general terms, of dimensional and qualitative and safety requirements (dials, scales, accuracy, junction parts : shank, socket, etc., installation accessories) and of test methods for checking fitness for purpose of pressure gauges such as industrial dial pressure gauges, pressure gauges with electrical limit contact devices and pressure gauges for checking the pressure and/or inflation of tyres according to Directive 86/217/EEC of May 1986. Pressure gauges used in welding, cutting and allied processes are excluded (covered by CEN/TC 121).

General Information
Frequently Asked Questions
CEN/TC 141 is a Technical Committee within the European Committee for Standardization (CEN). It is named "Pressure gauges - Thermometers - Means of measuring and/or recording temperature in the cold chain" and is responsible for: Standardization of basic and general terms, of dimensional and qualitative and safety requirements (dials, scales, accuracy, junction parts : shank, socket, etc., installation accessories) and of test methods for checking fitness for purpose of pressure gauges such as industrial dial pressure gauges, pressure gauges with electrical limit contact devices and pressure gauges for checking the pressure and/or inflation of tyres according to Directive 86/217/EEC of May 1986. Pressure gauges used in welding, cutting and allied processes are excluded (covered by CEN/TC 121). This committee has published 10 standards.
CEN/TC 141 develops CEN standards in the area of F05 - MEASURING INSTRUMENTS. The scope of work includes: Standardization of basic and general terms, of dimensional and qualitative and safety requirements (dials, scales, accuracy, junction parts : shank, socket, etc., installation accessories) and of test methods for checking fitness for purpose of pressure gauges such as industrial dial pressure gauges, pressure gauges with electrical limit contact devices and pressure gauges for checking the pressure and/or inflation of tyres according to Directive 86/217/EEC of May 1986. Pressure gauges used in welding, cutting and allied processes are excluded (covered by CEN/TC 121). Currently, there are 10 published standards from this technical committee.
The European Committee for Standardization (CEN) is a public standards organization that brings together the national standardization bodies of 34 European countries. CEN provides a platform for developing European Standards (ENs) and other technical documents in relation to various products, materials, services, and processes, supporting the European Single Market.
A Technical Committee (TC) in CEN is a group of experts responsible for developing international standards in a specific technical area. TCs are composed of national member body delegates and work through consensus to create standards that meet global industry needs. Each TC may have subcommittees (SCs) and working groups (WGs) for specialized topics.
This European Standard specifies requirements and testing for dial indicating thermometers using sensing methods of gas expansion (symbol GE), liquid expansion (symbol LE) and bimetallic strip (symbol BM). Nominal sizes are from 40 to 160, and temperature measurement from -100 °C to +700 °C.
Thermometers specified have circular scales, and are for industrial use only.
Thermometers of square form are also covered by this standard except for case, scale and pointer dimensions.
Annex A includes recommendations for selection and installation.
This standard does not apply to thermometers for medical use nor to thermometers with electrical limit contact devices.

This part of prEN 837 only applies to those pressure gauges whose pressure responsive element measuring system is a metal part which deforms under the effect of the pressure measured, as defined in prEN 837-1 and EN 837-3. This standard has been prepared to assist in the selection, installation and use of pressure gauges to ensure that they give satisfactory service for the intended application with the maximum level of safety.

This European standard specifies requirements for Bourdon tube (designated by B, see clause 12) indicating pressure gauges, vacuum gauges and combined vacuum and pressure gauges (compound gauges), with circular, spiral or coiled forms, from 40 to 250 nominal size with ranges up to 1600 bar for the measurement of gauge pressure. A reading of zero bar is atmospheric pressure.

This European standard defines requirements of pressure gauges for inflation of tyre and their testing in accordance with 86/217/EEC Directive. It establishes in the context of motor vehicles tyres, the minimum characteristics of the chain of measurement of mechanical apparatus intended to increase, inspect or adjust the pressure of tyres inflated by air or nitrogen. This apparatus classified in four different categories are hereinafter referred to by generic term, "pressure gauges".
