Selection and installation recommendations.17Bibliography.19ForewordThis European Standard has been prepared by Technical Committee CEN/TC 141 "Pressure gauges -Thermometers - Means of measuring and/or recording temperature in the cold chain", the secretariat of which isheld by AFNOR.This European Standard shall be given the status of a national standard, either by publication of an identical text orby endorsement, at the latest by May 2002, and conflicting national standards shall be withdrawn at the latest byMay 2002.This document includes a Bibliography.Annex A is informative.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden,Switzerland and the United Kingdom.1ScopeThis European Standard specifies requirements and testing for dial indicating thermometers using sensing methods ofgas expansion (symbol GE), liquid expansion (symbol LE) and bimetallic strip (symbol BM). Nominal sizes are from40 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 contactdevices.SIST EN 13190:2002

Elongated holes can be accepted to ensure interchangeability with previous standards.7.3Thermometer connectionThe type of connections in Figure 2 are used for both rigid stem thermometers and thermometers with capillary. Theconnections in Figure 3 are for rigid stem thermometers only. The length of "l5" of thermometer connection form 4depends of the length of the threaded part of its thermowell and shall be longer than the latter.The minimum height of the hexagon, square or flats shall be compatible with use of standard spanners according toISO 10102.7.3.1Screw threadsParallel pipe threads (symbol G) according to ISO 228-1.Taper pipe threads (symbol NPT) according to ANSI/ASME B1.20.1.ISO general purpose metric screw threads (symbol M) having basic profile according to ISO 68-1.Other threads specific to certain industries are acceptable.7.3.2Temperature detecting elementThe diameter of the temperature detecting element "d5" and its length "l1" (see Figures 2 and 3) will be atmanufacturer's discretion or should be by agreement between purchaser and supplier.7.3.3Sensitive portion of the temperature detecting elementThe length of the sensitive portion of the temperature detecting element "l2" (see Figures 2 and 3) shall be stated bythe manufacturer.SIST EN 13190:2002
