Description
This standard sets out the method for determining the steady-state thermal transmission properties of thermal insulating specimens using a guarded hotplate, within the limits set by Clauses 2.1, 2.2 and 2.3. For purposes of certification, this method is limited to specimens with thermal resistances greater than 0.017 m2.K/W in all directions (see Note 1).
Scope
Notes:
- Special techniques may be required for measuring surface temperatures with specimens having thermal resistances less than 0.1 m2.K/W.
- The accuracy of measurement on specimens of low-density thermal insulation by this standard may be difficult to verify and may require an extensive analysis of the equipment and/or a performance check using calibration standards having heat transmission characteristics and thickness similar to the test specimens. This standard is a primary method for measuring the thermal transmission properties of specimens, as only measurements of length, electrical power, and temperature difference are required.
