IEEE 382-1996/2006: Random Input Motion Sesimic Testing
IEEE Standard for Qualification of Safety Related Valve Actuators
RIM testing is designed for equipment that is connected with the pipeline systems in nuclear power plants and require functionality after extreme seismic events. The purpose of RIM qualification testing is to expose the equipment to the most accelerated and adverse aging mechanisms expected during its operating life before subjecting it to accident conditions.
Amplified excitation forces are generated at a single dominant frequency. To qualify equipment connected with pipeline systems the seismic excitation derived from the RIM curve must be additionally applied to generic seismic qualification RRS tests.
The RIM Tables at Clark Testing are capable of performing single-axis sweeps (OBEs) and single-axis Sine beats (SSEs) required for Actuator testing for Nuclear Plants. The tables are 4’ x 4’ square but can accommodate larger footprints. The single actuator per table can obtain the maximum required 6.6g ZPA levels spelled out in IEEE 344 & 382 at weights up to 10,000 lbs.
The RIM shaker generates loads on the equipment simulating the seismic response of the pipeline system. Clark seismic RIM shake tables are designed to meet the IEEE 382-1996/2006 standards. The shakers are 55,000 force pounds with a +5” stroke. The table can meet a peak velocity of 70”/ second (ips)
