Description
Charakteristische Materialgrösse, die die Wärmestromdichte in einem homogenen Stoff bei einer Temperaturdifferenz von einem Kelvin pro Meter unter stationären Verhältnissen angibt.
Description
Measure of the ability of a substance to conduct heat, determined by the rate of heat flow normally through an area in the substance divided by the area and by minus the component of the temperature gradient in the direction of flow.
Description
Grandeur spécifique des matériaux qui indique la densité du flux thermique traversant, en régime stationnaire, un corps homogène soumis à un gradient de température de 1 Kelvin par mètre.
Description
Grandezza caratteristica dei materiali che indica la densità di flusso termico nel caso di una differenza di temperatura di 1 Kelvin per metro in condizioni stazionarie in un materiale omogeneo.

Linguistic Context
Die Wärmeleitfähigkeit der Stoffe ist unterschiedlich; sie ist abhängig von Dichte, Struktur und Feuchte eines Stoffes.
Linguistic Context
La conductivité thermique l (lambda) indique la résistance qu’un matériau oppose au flux de chaleur.
Linguistic Context
La conduttività termica λ (Lambda) è la misura per la resistenza che un materiale da costruzione oppone al defluire del calore.
Term Note
EXP: Formelzeichen = λ; Masseinheit = W/(m·K); die Normen geben tabellierte Bemessungswerte an (a); je kleiner die Wärmeleitfähigkeit, desto besser die Wärmedämmwirkung des Baustoffes (b)
Term Note
EXP: symbol = λ; unit = W/(mK)
Term Note
EXP: symbole = λ; unité de mesure = W/m·K (a); plus la conductivité thermique est faible, meilleure est l’isolation (b)
Term Note
EXP: simbolo = λ; unità di misura = W/mK (a); più è bassa la conduttività termica, migliore è l'isolamento termico (b)
