Foam Testing
Foam samples are frequently fragile and must be handled with care. Do not use thermal
interface materials as they are difficult to clean off the foam. Foams use a power level of 90.
Foam samples must be a minimum of 2 mm thick to test.
Note on caring for foam samples: Always keep foams samples free of dirt or other substances
which will affect the foam results. Inspect before testing for dents or other forms of compression
damage. Store samples carefully to avoid such damage.
Step 1 – Place the sample on the sensor.
Handle the sample with gloves to prevent thermal contamination.
Step 2 – Carefully place a weight on the sample.
The 500 gram weight (supplied by C-Therm Technologies Ltd.) provides consistent pressure and
keeps the sample in good contact with the sensor surface.
Step 3 – Perform the test.
4.3
Powder Testing
Powders require a power level of 90. The sensor and weight must be applied carefully to provide
consistent compaction of the powder. There must be at least 1 mm of powder against the sensor
surface for testing.
Note: Volumes of powder as low as 3/8 tsp (1.85 mL) can also be tested with the Small
Volume Test Kit Accessory. Contact your C-Therm representative for more information.
Step 1 – Fill the 50 mL beaker to the 30 mL mark with the powder sample.
Step 2 – Place the sensor in the beaker so the sensor surface is in contact with the
powder.
Step 3 – Place the weight on the sensor.
Step 4 – Perform the test.
