| Abstract | The objective of this research is to reduce and eliminate errors of corrosion resistance testing process by applying general criteria of ISO/IEC 17025:2005 guideline on lab ability standard requirement and including statistical technique, such as, control chart and MSA to increase lab ability and also design the error controlling system of corrosion resistance testing process by applying FMEA technique in order to increase lab credibility. All issue found during each step of testing process will be collected and count, then use Pareto Diagram and Why-Why analysis technique, to identify the root caused an opportunity for improvement, based on the result from above data 3 major problems has been point out (1) Error from testing tool (2) Error result from analysis operation (3) Unstable on salt water pH value. After the testing process improvement has been implemented error down from 56% to 30.67%based on total number of testing panel and error down from 55% to 25.2% based on total number of testing, from every process, when use an error control system, by FMEA technique, RPN is reducing to 55.2 % average. |
