Compression Set

This test determines the compressive properties of rubber or elastomeric materials as specified in MIL-M-24041. Cylindrical specimens are compressed between parallel plates at a controlled rate while recording the force-deflection relationship.Compressive properties are important for materials used in seals, gaskets, grommets, and other components that must resist compression forces in service. The test provides data […] Read more

Assembly Resistance

Method 4.7.7.3 is an assembly resistance test for EMI/RFI shielding assemblies. Test current is applied at both ends of the assembly to measure the total electrical resistance of the shielding system.Assemblies with plugs shall be mated and the current applied on the test apparatus, while assemblies with grounding clamp connectors shall have clamp connectors attached […] Read more

Low pressure (maximum rated temperature)

Method 4.7.14 is a low pressure test at maximum rated temperature for flat power cables. Unless otherwise specified, the specimen length shall be 26 +/- 0.062 inches (660 +/- 1.6 mm). When a different specimen length is used, the insulation resistance and dielectric withstanding voltage results shall be proportional to the specimen length.The specimen is […] Read more

High-temperature aging

Method 4.7.11 is a high temperature aging test for flat power cables. A cable specimen 18 +/- 0.5 inches (457 +/- 13mm) in length has 0.25 +/- 0.10 inch (6.35 +/- 2.54 mm) of insulation removed from each end. The central portion of the cable is then bent at least halfway around a horizontally placed […] Read more

Folding

Method 4.7.10 is a folding test for flat power cables. A specimen of cable 26 +/- 0.062 inches (660 +/- 1.6 mm) is folded 180 degrees transversely and pressed between two pieces of smooth-surfaced flat metal twice the width of the cable, with a pressure of 301 pounds of force per inch of cable width.After […] Read more

Low Temperature Flex-Life

Method 4.6.2 is a low temperature flex-life test for cable assemblies containing molded sections or heat-shrunken transitions. The cable assembly is first aged in a circulating air oven for a minimum of 48 hours at 71 +/- 1C.The cable assembly is then conditioned for a minimum of 48 hours at the lower limit of the […] Read more
