TEMPERATURE
AND THERMAL SHOCK
Extreme temperatures are the leading cause of failure in almost all types of equipment.
Temperature testing is used to determine the thermal limits of operation of units, to
cause weak parts to show themselves, and to verify internal cooling/heating protection effectiveness. In most cases, a
thermal test should include both high and low test levels.
Our chambers can produce constant or cycling temperatures ranging from
-103° F to + 410° F (higher and lower in specialized cases). Test units may be operating or
dormant. Humidity and altitude may be varied with temperature. Automated controllers allow
around the clock documented tests.
In addition to thermal cycling, we can also perform thermal shock tests. These are
appropriate for products designed to withstand abrupt changes in temperature over a short
period. This test might be desirable for products moving from a warm warehouse into a cold
ambient temperature or for aircraft parts. Our thermal shock chamber can provide an almost
instantaneous move between the extremes you require.
SPECIFICATIONS
MIL-STD-810, 202; RTCA/DO-160; Telcordia; ASTM; SAE
EQUIPMENT
Multiple chambers with cascade and single stage cooling units, heaters, and
controlled air circulation. We perform thermal shock testing in a
Cincinnati Sub-Zero Chamber with transfer carriage dimensions of 17-1/2" x
18" x 18". Available shock temperature range from -103°
F to + 410° F. Larger chambers
can be adapted to thermal shock use with similar high and low ranges.
CAPABILITIES/LIMITS
Our largest temperature chamber is 8' x 12' x 24'. Temperature range from -110
degrees F. to +360 degrees F. Many combinations of humidity, altitude, and vibration are
available, along with greater temperature extremes for specialized tests. |
