• Analyze any defects or corrosion present in the material

• Compare results with industry standards to determine remaining life

• Consider factors like material type, operating conditions, and previous maintenance history

• Provide recommendations for repair or replacement based on findings

Mean while of working refers to the average time spent on tasks during work hours, impacting productivity and efficiency.

• Mean while of working is calculated by dividing total working time by the number of tasks completed.

• For example, if a technician completes 5 inspections in 10 hours, the mean while is 2 hours per inspection.

• Understanding mean while helps in identifying bottlenecks in processes and improving time management.

• It can also be used to set realistic deadlines and ...read more
