Abstract:  
QUALITY CONTROL TESTING SINCE 2007 Electronics Inc. (EI) developed a performance consistency testing program on their A and N Almen strips in 2007 to ensure they are consistent in thickness, flatness and hardness. The purpose of EI’s testing program is to verify that the strips will perform consistently, from lot to lot, from year to year. TESTING METHOD EI uses their own custom-built air blast cabinet with a variable speed rotary table with 39 Almen strip holders, a fixture for adjusting nozzle distance from the strips, a MagnaValve® for media flow rate control, and controls to adjust air pressure and table rotation.
