SM Series

The SM series thermal shock test chamber makes it possible to quickly and autonomously transfer test items back and forth repeatedly between a hot and cold environment. Thermal shock testing is different from thermal cycling, the latter being a longer and slower process. To see a more in-depth look at thermal shock versus thermal cycling, visit our About Test Chambers page. The SM series thermal shock test chamber is designed to create a 265ºC / 477ºF temperature variation very rapidly. Our standard thermal shock test chamber has two compartments, one heated and one cooled to support the rapid change in temperature exposure for the tested product. The product being tested is quickly transferred between the two zones by a pneumatic elevator. The SM series also can have a third compartment added for ambient temperature exposure to the product. The SM series is an air to air thermal shock test chamber.

SM series is both MIL-STD-883K and MIL-STD-202H compliant.

Safety Measures

We offer multiple types of safeties on our test chambers to help protect your product and your test chamber if anything malfunctions.

Heat Fuse: (Standard)

A heat fuse or thermal fuse, will interrupt the flow of electricity to the test chamber and shut it down if it reaches a certain temperature.

High Temperature Safety: (Standard)

A digital set temperature safety that will shut down the test chamber if it goes over a certain temperature.

High/Low Temperature Safety:

A digital set temperature safety that will shut down the test chamber if it goes over a certain temperature or below a certain temperature.


Optional Features:

  • Ambient Exposed Middle Compartment
  • Additional Basket
  • LN2 Boost Cool
  • CO2 Boost Cool
  • Desiccant Air Dryer
  • Window in Door(s)
  • Internal Vapor Proof Light(s)

MIL-STD-883K-TablesMIL-STD 883K Method 1010.9

On the left, the table specifies the test conditions the SM Thermal Shock test chamber can achieve under the military and aerospace conditions to adhere to the uniform method for thermal shock testing of microelectronic devices within electronic systems. These devices include monolithic, multi-chip, film and hybrid microcircuits, microcircuit arrays, and the elements from which the circuits and arrays are formed.

MIL-STD-202H-TableMIL-STD 202H Method 107

SM Thermal Shock test chambers are designed to meet Method 107 test conditions A, B, and F when testing electronic and electrical component parts such items as capacitors, resistors, switches, relays, transformers, inductors, and such at weights of 10 or 5 pounds, see table (left).

The test method should apply only to small component parts, weighing up to 300 pounds or having a root mean square test voltage up to 50,000 volts unless otherwise specified.
