I’m writing a shipping vibration requirement for an optical instrument we make and I’m not sure if I have all the necessary details to define it. The purpose is to define what vibration levels the unit can survive so the packaging (crate) designer knows how well he needs to protect the unit. I would like to write it so it is independent of the shipping method - such that if the shipping method changes the spec is still valid. Is this the standard way of writing this kind of spec or are they always tailored to the shipping method ?
From our own testing of this device we know it can comfortably handle 2.5 grms of random vibration and 50 g’s of shock. We believe it can handle the vib and shock indefinitely. My boss thinks (but he’s not sure) there is still missing information (i.e. bandwidth, frequency,?) to completely describe these levels. I talked to a packaging vendor who says “no”, but they may be biased to an underdefined spec ?
Thanks in advance,
John
