Thermal insulating products for building equipment and industrial installations - Determination of the coefficient of thermal expansion (ISO 18099:2022)

This document specifies the equipment and procedures for determining the coefficient of linear thermal expansion. It is applicable to thermal insulating products within the temperature range −196 °C to 850 °C, subject to the possible temperature limitation of the test specimens. It is not applicable to products which experience dimensional changes during the test due to the loss of hydration water or which undergo other phase changes.

Toplotnoizolacijski proizvodi za opremo stavb in industrijske inštalacije - Ugotavljanje koeficienta toplotne razteznosti (ISO 18099:2022)

Ta evropski standard določa opremo in postopke za ugotavljanje koeficienta toplotne razteznosti. Ta standard se uporablja za toplotnoizolacijske proizvode v temperaturnem območju od 196 °C do 850 °C ob upoštevanju morebitne temperaturne omejitve preskušancev. Ne sme se uporabljati za proizvode, pri katerih pride med preskusom do dimenzijskih sprememb zaradi izgube hidratacijske vode oziroma drugih faznih sprememb.
OPOMBA: Zaradi majhnih dimenzij naj bo preskušanec skrbno izbran, da bo reprezentativen za proizvod, ki se preskuša.

Overview

EN ISO 18099:2022 - "Thermal insulating products for building equipment and industrial installations - Determination of the coefficient of thermal expansion" (CEN adoption of ISO 18099:2022) specifies the equipment and procedures to determine the coefficient of linear thermal expansion of thermal insulating products. The standard covers testing across a wide temperature range (−196 °C to 850 °C), subject to the limitations of the specimens, and excludes materials that change dimensionally due to loss of hydration water or other phase changes.

Key Topics

• Scope and exclusions: Applicable to thermal insulating products for building and industrial installations; not applicable when irreversible dimensional changes (e.g., dehydration, phase transitions) occur during the test.
• Test principle: Measurement of reversible linear dimensional changes as a function of temperature - either continuously over a temperature range or between two specified temperatures to obtain a mean coefficient.
• Apparatus requirements:
  • Dilatometer (tube or rod type; vitreous silica commonly used)
  • Micrometer calliper or displacement transducer for length measurement with specified accuracy
  • Electrical furnace (for high temperatures) and test chamber (for low/cryogenic temperatures), each able to control mean specimen temperature and limit temperature-change rates to 1 °C/min
  • Calibrated thermocouples connected to continuous recording devices (accuracy: ±0.5 K from −196 °C to 200 °C; ±1 K from 200 °C to 500 °C; ±2 K from 500 °C to 850 °C)
• Specimen preparation:
  • Typical specimen size guidance (e.g., (50 ± 1) mm length with 10 mm cross-section), with dimensions chosen to match dilatometer geometry and product characteristics
  • Conditioning and number of specimens as per product standard or agreement between parties
• Results and accuracy:
  • Definitions for mean coefficient and instantaneous coefficient at temperature
  • Reporting requirements and limits on measurement uncertainty

Applications

Who uses EN ISO 18099:2022 and why:

• Manufacturers of thermal insulation to validate dimensional stability with temperature changes
• Testing laboratories and quality control teams performing dilatometer tests
• Specifiers and engineers designing building services and industrial installations who need predictable thermal movement data
• R&D teams assessing new insulation materials across cryogenic to high-temperature applications Practical use cases include thermal expansion data for pipe insulation, equipment insulation, cryogenic systems and high-temperature process lines.

Related Standards

• Supersedes EN 13471:2001 and integrates earlier ISO work (ISO 18099:2013).
• Prepared by ISO/TC 163 (Test and measurement methods) in collaboration with CEN/TC 88 (Thermal insulating materials and products).

Keywords: EN ISO 18099:2022, coefficient of thermal expansion, linear thermal expansion, thermal insulating products, dilatometer testing, temperature range −196 °C to 850 °C, thermocouple accuracy.
