SERVICES FOR NIST TRACEABILITY OF VIBRATION MEASUREMENTS FOR     

PORTABLE VIBRATION MEASUREMENT EQUIPMENT.                        

                                                                 

PRIOR TO A MERGER BETWEEN ENTEK SCIENTIFIC AND IRD MECHANALYSIS, 

INC., IN 1996, AUDITS WERE PERFORMED BY PACIFIC GAS & ELECTRIC   

AGAINST 10 CFR PART 50, APPENDIX B, AND THERE WAS A QUESTION OF  

THE ACCURACY OF THE CALIBRATION CERTIFICATES BEING PROVIDED BY   

IRD MECHANALYSIS, INC.  IRD MECHANALYSIS, INC., HAD BEEN         

PROVIDING CALIBRATION CERTIFICATES INDICATING ACCURACY FOR       

TRANSDUCERS CALIBRATED ON ITS UNHOLTZ-DICKIE SHAKER TABLES WITH A

4:1 ACCURACY RATIO WHEN IT ACTUALLY HAD A 3.125:1 ACCURACY RATIO.

 THE COMPANY IS ADVISING LICENSEES TO EVALUATE THE IMPACT OF A   

CHANGE FROM A 4:1 ACCURACY RATIO TO A 3.125:1 ACCURACY RATIO.
