Overview
This test procedure is used for measuring temperatures
associated with the
pressure chamber. Sometimes materials can weaken due to heat and
thermal tests need to be performed in order to make sure the
materials stay within the correct temperature range. |
Caution
Due to pressures involved, this experiment should be carried
out behind a safety barrier.
Equipment
- Air source. This includes pumps, tanks, compressors etc.
- Pressure gauge
- Thermometer / thermocouple
Procedure
This is a general procedure for measuring internal
temperatures as it will depend on what is being tested
and what temperature measuring equipment is available.
- Prepare the pressure chamber for the test by
mounting it securely and attach it to the air source.
- Attach the thermometer or thermocouple to the
desired location in the pressure chamber. Where this
is located will depend on what is being measured.
- Pressurise the pressure chamber and record
readings.
- Depressurise the pressure chamber.
Notes
- It is a good idea to video tape the experiment that
includes the pressure gauge and temperature reading for
later analysis.
