34、EN ISO 22007-2:2015 (E) DIN EN ISO 22007-2:2015-12 IntroductionA significant increase in the development and application of new and improved materials for broad ranges of physical, chemical, biological, and medical applications has necessitated better performance data from methods of measurement of

35、thermal-transport properties. The introduction of alternative methods that are relatively simple, fast, and of good precision would be of great benefit to the scientific and engineering communities. 1A number of measurement techniques described as transient methods have been developed and several ha

36、ve been commercialized. These are being widely used and are suitable for testing many types of material. In some cases, they can be used to measure several properties separately or simultaneously. 2,3A further advantage of some of these methods is that it has become possible to measure the true bulk

37、 properties of a material. This feature stems from the possibility of eliminating the influence of the thermal contact resistance (see 8.1.1) that is present at the interface between the probe and the specimen surfaces. 1,3,4,5,65EN ISO 22007-2:2015 (E) DIN EN ISO 22007-2:2015-12 1 ScopeThis part of

38、 ISO 22007 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 en

39、vironments at a range of temperatures and pressures.This method is suitable for testing homogeneous and isotropic materials, as well as anisotropic materials with a uniaxial structure. The homogeneity of the material extends throughout the specimen and no thermal barriers (except those next to the p

40、robe) are present within a range defined by the probing depth(s) (see 3.2 below).The method is suitable for materials having values of thermal conductivity, , in the approximate range 0,010 Wm1K1 500 Wm1K1, values of thermal diffusivity, , in the range 5 108m2s1 104m2s1, and for temperatures, T, in

41、the approximate range 50 K T 1 000 K.NOTE 1 The specific heat capacity per unit volume, C, can be obtained by dividing the thermal conductivity, , by the thermal diffusivity, , i.e. C = /, and is in the approximate range 0,005 MJm3K1 C 5 MJm3K1. It is also referred to as the volumetric heat capacity

42、.NOTE 2 If the intention is to determine the thermal resistance or the apparent thermal conductivity in the through-thickness direction of an inhomogeneous product (for instance a fabricated panel) or an inhomogeneous slab of a material, reference is made to ISO 8301, ISO 8302, and ISO 472.The therm

43、al-transport properties of liquids can also be determined, provided care is taken to minimize thermal convection.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
