Temperature Testing - Humidity Testing Laboratory Services

RMTS, an independent, contract humidity and temperature testing lab services, features multiple temperature and temperature/humidity chambers used for testing small to medium products or packages at specified temperature and humidity conditions for long durations or can be used to cycle between hot/cold temperatures as well as humidity.

Humidity causes corrosion problems, electrical failures, accelerates wear on moving parts, and infiltrates plastics and coatings. Temperature and humidity testing can evaluate the performance of electronic, metal and plastic products, corrosion resistance, and coatings in humid environments. Our equipment can test to exact environments and international standards, using both temperature and humidity in constant or variable conditions. RMTS can also provide combined environmental testing with temperature, humidity and vibration or temperature and altitude simultaneously.For example, our combination conditions capabilities are used for the MIL-STD-810 test series that addresses a range of environmental conditions including low pressure testing, high and low temperatures, rain (wind blown and freezing), humidity, salt fog, dust and sand exposure, vibration and shock, and more. This is of great value in testing the environmental merit and durability of a system design - pre-launch.

    Our environmental test chambers are capable of producing conditions to meet the following testing standards:

  • MIL-STD 810F method 507.4, 501.4, 502.4
  • MIL-STD 883G method 1004.7
  • RTCA DO-160
  • ASTM
  • ISTA
  • SAE (Society of Automotive Engineers)
  • EIA (Electronic Industries Alliance)
  • JEDEC (Joint Electron Devices Engineering Council) method A101-B
  • JIC testing standards
