Reliability Test (Korea Institute of Machinery & Materials - KIMM)

Zero-failure test operation has been carried out in cooperation with KIMM. Below picture shows the reliability test instruments manufactured as a technical development project through the joint investment by public and private enterprise in 2013. To guarantee the life span, the calculation is based on the confidence level 95% and life span 26,280 hours (Assurance life span: 3 years) to guarantee. Main failure was the seal wearing and since it is equal to the wearing specified in 'Machinery Failure Analysis and Troubleshooting', a shape parameter [β] 3.0 was quoted.
