We are a small Steel Processing facility attempting QS9K certification. The problem we are having at this point is interpreting what is specificly required for an in-house calibration lab. In basic terms, our Plant Manager calibrates our Micrometers, Calipers and Master Tape measure in his office. He uses a Calibration software system to record the information and creates records. The question is, do we have to create an entire quality system for this activity ie lab scope, procedures, work instruction, measurement uncertainty/error (still can't figure instrument error out)? I need to know the simplest method available to get us through this.
