 3I Series Cases: Military Spec Certifications
September 20, 2005
SKB was recently awarded a large US Military contract for transit cases designed to house a life saving piece of personal safety equipment designed for NBC (Nuclear, Biological, & Chemical) warfare threats. Due to the extreme operating environment, and vital importance of the mission, the specifications required that our customer complete a full battery of Military Standard testing on our 3I series case.
All testing was done at an ISO/IEC 17025 and ISO 9001 certified third party test laboratory. The case being tested was our 3I-2011-7B, but the entire series would be qualified by reasons of similarity. The following are the Military Standard tests that we performed, and passed successfully:
