7.6.2. performance testing of insulation1) test performance in thermal insulationUsing a Heat Flow Meter testing machine by means of a heat transfer rate measure from top down to the bottom of the test piece. To the function value, characterised by permissions apply heat (Thermal conductivity, K-Value). 2 performance test), the rate of water absorption of heat insulation materials.Test with a sample size of าง × length × broad thickness equal to 360 mm × 25 mm × 13 mm after the test by measuring the size and scale of the test pieces note the exact size, little and then take the test pieces in a vertical, and test their PCs as U , sinking just chat in the middle of the test piece at the bottom that was their long dang. 306 mm. soak leaves little 24 hrs. After that, lift the test piece, drain. Report on the results of the test. -The weighted average of the test piece before the test. -The weighted average of the test after the test pieces. -The weighted average of the water is to absorb by the test pieces.
