Hi,

I was referring to some of papers available on internet for HALT test guidelines. For Vibration tests, the paper says that chamber requirements should be -> Vibration output without load from 1 Grms to a minimum of 35 Grms.

But for test equipment, accelerometer range is +/- 500g.

I am confused what is the difference between g and Grms. How to select proper accelerometer?

Please help.

Thanks for your help in advance.

Regards,
Samir

One Response to Difference Between G and Grms

    Hi, Samir..

    actaully G represents Peak value of Acceleration while Grms represents RMS(Root Mean Square) Value of Acceleration.
    generally in Peak sine or sweep sine vibration we use G while in random Vibration Testing we use Grms.

    hope above is clear to u.
