No idea. It looks like a typo.

The frequency part is pretty obvious – any idea how to interpret the acceleration part (>10/2 G) of this spec?

Sinusoidal vibration a point on the test article will describe a circle, in a plane inclined 45 degrees to the horizontal plane, the diameter of which is equal to the double amplitude specified.

Yes we can.

Durham and I need to random sine vibration testing on valves that go on truck engines at temperatures of minus 40 degrees to 130 degrees C are you able to test to theses conditions?

Best Regards

Even a beginner will understand with ease. Hats off!!!!!

There are some specifications that allow the frequency range to be split for sinusoidal vibration. I do not know of any random vibration specifications that allow you to split up the frequency range. That would be a good question for the Linkedin Group Vibration and Shock Test, https://www.linkedin.com/groups/737267.

Is there a specification that allows this or disallows this? Currently my shaker is not capable of the full spectrum
