Impact
Clarified that equipment suitability depended on which vibration standard applied, giving the owner a specific issue to resolve before making a decision.
Challenge
The 12th-floor vibration environment needed evaluation for sensitive scientific equipment against applicable velocity and acceleration criteria.
STRAAM approach
On February 20, 2013, STRAAM measured five accelerometer configurations at 50 positions from 7 a.m. to 5 p.m. and compared results with both criteria.
Result
The evaluation reached different conclusions under the two criteria considered. STRAAM asked the owner to confirm which standard governed; the findings do not support a blanket suitability claim.
