This was developed as a miniature test rig for the testing of thermal insulation of fabrics, compliant with ISO 5085 specifications.
This system automatically performs a ‘two-plate thermal resistance test’ with minimal user input. Samples of approximately 85mm diameter can be tested in as little as 2 hours. The sample’s thermal resistance (R-value) is displayed on the monitoring computer, and detailed logs of the test are produced in a standard XML format for further analysis in a wide range of software.
Repeated test results on the same samples vary by less than 5%, with typical results being within 1% of each other.
