Frequently Asked Questions

  • How it works

    First, I collect your Type A and calibration history data. Next, I analyze that data to determine the magnitude of uncertainty. Then, I calculate the uncertainty and issue a report of my findings.
  • What’s it cost

    Project pricing varies with the size and complexity of the project. Most uncertainty analysis cost $200 per CMC, but can range from $100 to $500 per CMC.
  • How long does it take

    The duration of a typical project varies by the size of the project. Most small projects are completed in a month. While larger project may take up to 3 to 6 months.
  • What do I get

    Upon completion of the project, you will receive a report for each uncertainty analysis performed. Each report includes a summary with the CMCs for your scope of accreditation and  the associated uncertainty budgets.
