Plastics - Determination of thermal conductivity and thermal diffusivity - Part 2: Transient plane heat source (hot disc) method (ISO 22007-2:2015)

ISO 22007-2:2015 specifies a method for the determination of the thermal conductivity and thermal diffusivity, and hence the specific heat capacity per unit volume of plastics. The experimental arrangement can be designed to match different specimen sizes. Measurements can be made in gaseous and vacuum environments at a range of temperatures and pressures.

Plastiques - Détermination de la conductivité thermique et de la diffusivité thermique - Partie 2: Méthode de la source plane transitoire (disque chaud) (ISO 22007-2:2015)

ISO 22007-2:2015 spécifie une méthode pour déterminer la conductivité thermique et la diffusivité thermique, et de ce fait la capacité calorifique spécifique par unité de volume, des plastiques. Le dispositif expérimental peut être conçu pour s'accorder à différentes tailles d'éprouvette. Les mesurages peuvent être effectués dans des environnements gazeux et sous vide sur une plage de températures et de pressions.

Polimerni materiali - Ugotavljanje toplotne prevodnosti in toplotne razprševalnosti - 2. del: Metoda s tranzientnim ploskovnim toplotnim virom (vroči disk) (ISO 22007-2:2015)

Ta del standarda ISO 22007 določa metodo za ugotavljanje toplotne prevodnosti in
toplotne razprševalnosti ter posledično specifične toplotne kapacitete polimernih materialov na enoto prostornine. Eksperimentalna ureditev je lahko oblikovana tako, da ustreza različnim velikostim vzorca. Meritve je mogoče opravljati v plinskem in vakuumskem okolju pri različni temperaturi in tlaku.
Ta metoda je primerna za preskušanje homogenih in izotropnih materialov ter anizotropnih materialov z enoosno strukturo. Homogenost materiala se razteza po celotnem vzorcu in ni prisotnih toplotnih pregrad (razen poleg sonde) v območju, opredeljenem z globino sondiranja (glej 3.2 spodaj).
Metoda je primerna za materiale z vrednostmi toplotne prevodnosti, λ, v približnem območju 0,010 W⋅m−1⋅K−1 < λ < 500 W⋅m−1⋅K−1, vrednostmi toplotne razprševalnosti, α, v območju 5 × 10−8 m2⋅s−1 < α < 10−4 m2⋅s−1 in temperatur, T, v približnem območju 50 K < T < 1 000 K.
OPOMBA 1: Specifično toplotno kapaciteto na enoto prostornine, C, je mogoče pridobiti z deljenjem toplotne prevodnosti, λ, s toplotno razprševalnostjo, α, tj. C = λ/α, pri čemer je ta količnik v približnem območju 0,005 MJ⋅m−3⋅K−1 < C < 5 MJ⋅m−3⋅K−1. Zanj se uporablja tudi izraz prostorninska toplotna kapaciteta.
OPOMBA 2: Če želite ugotoviti toplotno upornost ali dejansko toplotno prevodnost nehomogenega izdelka v smeri skozi debelino (na primer izdelane plošče) ali nehomogene plošče iz enega materiala, upoštevajte standarde ISO 8301, ISO 8302 in ISO 472.
Ugotoviti je mogoče tudi lastnosti toplotnega prenosa za tekočine, vendar je treba posebej paziti na zmanjšanje toplotne konvekcije.
