2. DESCRIPTION OF TEST EQUIPMENT

The test equipment used was a Laser Comp Fox 600 heat flow meter. The specimen for testing is placed horizontally in the apparatus, with upwards heat flow. The hot and cold plates each have a 250 mm x 250 mm heat flux transducer embedded in their surface. The edges of the specimen are insulated from the room ambient temperature.

3. PROCEDURE

The specimen was supplied by the client and consisted of one piece of light green polystyrene. The dimensions of the sample were 595 x 595 mm. It was tested at its actual thickness, to the requirements of ASTM C518-04.

4. RESULTS

These measurements comply with the requirements of ASTM C518. The uncertainty in the measurements of thermal conductivity and thermal resistance are estimated to be ± 3%.
