The purpose of Resistance to Solvents testing is to determine the ability of a device to withstand exposure to solvents so that the solvents do not cause deleterious, electrical or mechanical damage, or deterioration of the material or finishes.
This test consists of immersing three groups of devices into one of three solvents for a minimum of one minute. After fully immersing the device, it is removed and brushed with ten strokes across the portion of the device where marking has been applied. This is repeated two additional times. After the 3rd immersion and brushing, the devices are rinsed and all surfaces air blown dry. After five minutes, the devices are examined to determine if any damage has occurred. Any damage is considered to be a failure as well as any missing, faded, smeared, or blurred markings.
Silicon Cert Laboratories (SCL) has recently received Commercial Laboratory Suitability Status for MIL-STD-883, Method 2015 Resistance to Solvents testing through the Defense Logistics Agency (DLA).
