In 2010, the ILAC P14 policy was introduced and changed the way calibration laboratories calculate and report calibration uncertainty in their certificates. As a result, many laboratories have struggled to calculate calibration uncertainty in accordance with this policy and have been cited for nonconformances.<\/p>\n
Therefore, I have created this guide to show you how to calculate calibration uncertainty in 8 easy steps.<\/p>\n
In this guide, I will cover the process to calculate calibration uncertainty in great detail with pictures, professional tips, and examples. Plus, I have created a great calibration uncertainty calculator for Microsoft Excel<\/a> to make the process even easier.<\/p>\n This guide also\u00a0covers how to use this uncertainty calculator\u00a0every step of the way, so you can easily calculate calibration uncertainty for your calibration reports.<\/p>\n <\/p>\n The ILAC P14 policy covers three main sections, ILAC\u2019s policy on;<\/p>\n In this guide, I will cover how to calculate uncertainty in measurement results for calibration certificates (i.e. section 6) in accordance with the 2013 edition of the ILAC P14 Policy. Specifically, I will cover the requirements of 6.2 through 6.5 and how they affect the way you calculate uncertainty.<\/p>\n <\/p>\n In accordance with section 6.4 of the ILAC P14 policy, the estimated calibration uncertainty should include the following contributors;<\/p>\n If you are confused and not sure how to include these contributors in your calibration uncertainty estimate, do not worry. I am going to cover everything that you need to know (and more) in this guide.<\/p>\nILAC P14 Policy<\/h2>\n
