About
This course will instruct and evaluate you on basic concepts of uncertainty management. You will understand and describe the terminology, concepts, and procedures relating to ISO compliance and uncertainty management including tolerances, specifications, accuracy, uncertainty ratios, guard banding, and changes to and adjustment of inspection decision rules.
Learning Objectives:
- Understand and apply key concepts relating to specifications, tolerances and measurement uncertainty quality
- Read and interpret published specifications
- Calculate accuracy ratios and guard bands for various purposes
Who Should Attend:
Calibration Coordinators, Calibration Technicians and Engineers, Quality Coordinators and those seeking understanding of the ISO 17025 standard and compliance to it.
Outline:
- Introduction
- Communicating about measurements and measurement equipment
- What is a Specification?
- Why do we need specifications?
- The use of specifications in measurement and metrology
- The form(s) taken by specification
- Some examples of specifications of measuring equipment
- How to read and interpret specifications
- The importance of specifications in calibration
- What it means to be in or out of spec.
- Practice reading, interpreting, calculating
- What is a Tolerance?
- How are tolerances stated?
- What is the difference between a tolerance and a specification?
- Some examples of tolerances of measuring equipment
- How to read and interpret tolerances
- The importance of tolerances in calibration
- What it means to be in or out of tolerance
- Practice reading, interpreting, calculating
- Measurement Uncertainty (this is not a full treatment, just an intro in context)
- Definitions (in context) of measures of measurement reliability and quality
- Accuracy
- Precision
- Resolution
- Repeatability and Reproducibility
- Traceability
- How do these definitions fit with specifications and tolerances?
- Special cases: floor specs, percent of full scale versus percent of reading, ppm, values near zero
- Calculation of measurement uncertainty – budgets
- Converting specifications and tolerances to uncertainty
- Practice calculating
- Accreditation (rules relating to specifications and tolerances)
- Ratios
- The 10:1 principle; 4:1, 3:1
- What did they mean in the past: Definitions in MIL-STD-45662
- What do they mean now? Definitions in ANSI/NCSL Z-540-1, ISO 10012-1 and ISO/IEC 17025. Are they useful? If so, why?
- Accuracy ratios, tolerance ratios, uncertainty ratios
- Ratios and traceability
- Practice calculations
- Specifications, Tolerances, and Uncertainty
- Inspection and test
- Errors of Type I
- Errors of Type II
- Decision rules
- Definitions
- Applying them
- Responsibility (whose)
- Measurement uncertainty and decision rules
- Changes to and Adjustment of Decision Rules
- Guard banding
- Determining conformance to identified metrological specifications and taking measurement uncertainty into account
- Practice calculation
Training Methodology
Pathways Training and consulting adopts the newest techniques of human resources Training and consulting and, with the following:
- Theoretical lectures are delivered via PowerPoint and visual displays (videos and short films)
- Making scientific evaluation to the trainee (before and after)
- Brainstorming and role-playing
- Using case studies related to the scientific material being delivered and the trainees' work.
- The participants get the scientific and practical material printed and on CDs and Flash memories.
- Preparing records and reports of the participants' attendance and results, with a general evaluation of the training program.
- A group of the best trainers and experts in all fields and specialties professionally prepares the scientific material.
- After finishing the course, the participants get certificates of attendance signed, certified, and issued by pathways Training and consulting.
- Our training programs start at 9:00 o'clock in the morning and end at 2:00 in the afternoon, with snack buffet during the lectures.
- Providing a lunch buffet during the training program period, with organizing a lunch party on the training program final day for taking some photos and certificate awarding.
