Abstract
The CORD Group Limited was contracted by the Defence and Civil Institute of Environmental Medicine to determine the thermal resistance of the MAC 200 immersion suit and the current Constant Wear Dry immersion suit with different liners (current liner, closed cell foam liner (3 mm), and variable insulation liner (losed cell foam with 3 mm on the front and 12 mm on the back)), some of them being under developmental phase. The thermal resistance of these suits and liners was determined utilizing a thermal instrumented manikin test system. This report describes the thermal manikin test system, the protocols and the results for each item tested. A total of 10 tests were conducted, with each test measuring the thermal resistance of each suit and liner. The tests were all conducted with the manikin immersed in water with a significant wave height of 30 cm with a wave period of 2.5 seconds. Tests were conducted in 3 conditions: no artificial leakage, 2 liters of leakage, and 4 liters of leakage. During dry tests, the thermal resistance of the MAC 200 immersion suit was about 10% higher than the thermal resistance of the Constant Wear Dry immersion suit, and the difference between the two suits doubled to about 20% during the wet tests.
