The Quality Calibration Handbook: Developing and Managing a Calibration Program
Learn How to Implement a Calibration Program For Your Company's Equipment
How to design, implement, maintain, and continuously improve a quality calibration system, with all the required documentation, traceability, and known uncertainty for each and every item of test equipment owned and used by any company, large or small. It will benefit companies that want to implement a program and also those that already have one in place. Some industries have tighter requirements than others on how they treat calibration; some are more specific about how their standards are read, while being vague about what is needed to meet calibration. 190 pages.
