Subject: MIL STD 810E SAND AND DUST TEST
Message:
The company I am employed by manufactures optical equipment which is fitted to Rotary as well as fixed wing cargo aircraft. We were contracted to perform a sand and dust test on the quartz lense of the specific LRU in question in accordance with MIL STD 810E method 510.3. The lense was sandblasted to a opaque condition and the result of the test was a fail for the LRU. Is there any method that one can equate this test to any type of operation or flying hours. Is this test a requirement for all airborne optical equipment.
