ISO 17139:2014 describes methods for the determination of linear thermal expansion characteristics of ceramic matrix composite materials up to 2 300 K, and is applicable to 1D, 2D, and nD materials. The method describes general principles of construction, calibration, and operation of the equipment.

Overview

EN ISO 17139:2022 (ISO 17139:2014) specifies standardized methods for determining the linear thermal expansion of ceramic matrix composite materials (fine ceramics / advanced ceramics) up to 2 300 K. Adopted by CEN as EN ISO 17139:2022, the standard covers construction, calibration and operation principles for apparatus used to measure thermophysical properties - especially the coefficient of thermal expansion (CTE) - of 1D, 2D and nD ceramic composites.

Key topics and technical requirements

Scope and principles

Measurement of length change during controlled heating and cooling cycles; continuous or frequent interval recording.
Two permitted methods: direct measurement (measuring test-piece displacement vs. calibrated support system) and differential method (measuring length change between a reference piece and test piece).

Temperature range and atmosphere

Applicable to temperatures up to 2 300 K.
For temperatures above 1 400 °C, use vacuum or inert gas atmosphere and non-oxide materials (e.g., dense graphite) when appropriate.
For temperatures beyond ~2 000 K, infrared detectors or suitable high-temperature sensors may be used.

Instrumentation and accuracy

Furnace control to within 1% of mean temperature (in K).
Thermocouples per IEC 60584-1; tungsten–rhenium couples may be used at higher temperatures (not covered by IEC 60584-1) and should be calibrated individually.
Displacement measurement accuracy better than 0.1 μm; dimensional measurement accuracy better than 0.05 mm.
Periodic calibration required (Annex A for direct, Annex B for differential).

Specimen mounting

Holders and push rods must be thermomechanically stable, chemically inert and thermally compatible with test material.
Mounts must allow free axial movement, minimize stresses and restrict lateral motion without constraining axial expansion.

Applications and users

EN ISO 17139:2022 is intended for:

Materials testing and dilatometry labs performing CTE characterization of ceramic matrix composites.

R&D teams and quality control in advanced ceramics, aerospace, power generation, electronics and high-temperature component manufacturers.

Engineers and designers who need validated thermal expansion data for thermal stress analysis, component design and lifetime prediction.

Accredited testing laboratories seeking compliance with normative references such as ISO/IEC 17025.

Practical applications include qualification of ceramic composites for thermal cycling, matching CTEs in multi-material assemblies, and supplying certified thermophysical data for simulation and specification.
