La présente Norme européenne spécifie les essais de vérification primitive et s'applique aux compteurs d'énergie thermique, c'est-à-dire aux instruments destinés à mesurer l'énergie thermique qui, dans un circuit d'échange thermique, est absorbée (refroidissement) ou cédée (chauffage) par un liquide appelé liquide « caloporteur ». Le compteur d'énergie thermique fournit la quantité d'énergie thermique en unités de mesure légales.
La présente Norme européenne ne traite pas des exigences de sécurité électrique.
La présente Norme européenne ne traite pas des exigences de sécurité relative à la pression.

EN 1434-5:2007 (E) 4 1 Scope This European Standard specifies initial verification tests and applies to heat meters, that is to instruments intended for measuring the heat which, in a heat-exchange circuit, is absorbed (cooling) or given up (heating) by a liquid called the heat-conveying liquid. The heat meter indicates the quantity of heat in legal units. Electrical safety requirements are not covered by this European Standard. Pressure safety requirements are not covered by this European Standard. Surface mounted temperature sensors are not covered by this European Standard. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 1434-1:2007, Heat meters — Part 1: General requirements EN 60751:1995, Industrial platinum resistance thermometer sensors (IEC 60751:1983 + A1:1986) 3 General Initial verification of a measuring instrument is a series of tests and visual examinations carried out to determine whether an instrument manufactured to replicate a given pattern conforms to that pattern and to regulations, and that its metrological characteristics lie within the limits of the maximum permissible errors. If the instrument passes all tests and examinations, it is given legal character by its acceptance as evidenced by stamping and/or issuance of a certificate of verification. The provisions of this standard also apply to the re-verification of heat meters. The instrument shall be tested under rated operating conditions at the extremes and midpoints of its ranges. Initial verification is divided into metrological, technical and administrative phases. In tests of a heat meter as a combined instrument, the flow sensor, the temperature sensors and the calculator shall each be tested separately. Unless otherwise stated in the certificate of pattern approval, the verification shall be carried out in accordance with this standard. NOTE Modern heat meters are mainly equipped with CMOS microprocessors with a very low power consumption, allowing battery operation. Testing and adjusting of this type of meter needs a completely different approach. Until now, almost every meter type needed its own test equipment to handle the manufacturer's specific requirements. This is a very complicated and expensive way for users of several types of meters and for initial verification institute
