Thermal and Insulation Performance Testing
category
Thermal performance testing quantifies heat transfer, insulation value, radiant heat resistance, and thermal contact properties of textile assemblies using guarded hotplate, sweating guarded hotplate, infrared radiometry, and cone calorimetry instruments under standardised environmental conditions.
Role
Enables engineering of thermally functional garments for cold protection, heat stress management, fire safety, and building insulation, providing the measurable thermal data required by occupational safety standards and consumer product claims.
