4200: Internal Calibration of Laboratories

In Class - 1 Day
Virtual - 2 half days


Learn to competently propagate the uncertainties associated with temperature, volume, and mass from laboratory reference instruments to those instruments used for testing. Establish credible traceability of measurement. Ensure that internal calibration procedures meet competence criteria for the desired levels of uncertainty to be propagated.

Note: This course is not intended for laboratories that calibrate instruments for use by other laboratories.

Who Should Attend

For all laboratory staff involved in laboratory testing operations and QA/QC procedures:

  • Writing procedures
  • Conducting tests
  • Conducting QA/QC
  • Preparing standards
  • Purchasing calibration services

Course Overview

This 1-day Training Course is for participants to learn to competently propagate uncertainties for mass, temperature, and volume instruments in the range parts per ten to parts per thousand the smallest uncertainties can be propagated in a testing lab.

Participants are provided training material related to basic measurement instrument calibration and a listing of supporting information.

Learning Objectives

  • Theory and principles of calibration regarding the parameter under discussion (Mass or Volume or Temperature)
  • Uncertainty contributions during the calibration process
  • Calibration procedures for the types of instrument under discussion
  • Calculation of the uncertainty propagated through the calibration
  • Determination of the uncertainty contribution of the calibrated device within laboratory testing work.
  • Real examples to work through and develop solutions to common calibration situations
  • A listing of supporting information available from public agencies that support the science of measurement for that parameter.
