This document specifies the test method for the determination of thermal diffusivity from room temperature to at least 1 700 K by the flash method for homogeneous monolithic ceramics with porosity less than 10 %. Flash methods, like laser flash, are applicable to homogeneous isotropic materials with thermal diffusivity values ranging from 0,1 to 1 000 mm2 s-1 within the temperature range from approximately 100 K to 2 300 K. The method described in Annex G describes how to estimate, on the basis of the thermal diffusivity test, the specific heat capacity and the thermal conductivity of homogeneous monolithic ceramics with porosity less than 10 %.
Abstract
Overview
EN ISO 18755:2023 - "Fine ceramics (advanced ceramics, advanced technical ceramics) - Determination of thermal diffusivity of monolithic ceramics by flash method (ISO 18755:2022)" - is a CEN-adopted ISO test standard for measuring thermal diffusivity of homogeneous monolithic ceramics. The method covers measurements from room temperature to at least 1 700 K for specimens with porosity less than 10% and describes flash techniques (e.g., laser flash or flash-lamp) applicable across a broad temperature range (approximately 100 K to 2 300 K) and thermal diffusivity values from 0.1 to 1 000 mm2·s‑1. Annex G describes how to estimate specific heat capacity and thermal conductivity from flash data.
