A Guide to Calculating the Uncertainty of the Performance of Environmental Chambers

This Guide to Calculating the Uncertainty of the Performance of Environmental Chambers was published in October 2003. This document, was submitted to the IEC and forms the basis of IEC60068-3-11, which was published in 2007. The document deals with uncertainties in both temperature and humidity measurements in environmental chambers, and some people may find it more readable than the IEC document, although, of course the two documents are consistent.

EE December 2004 Leader

The work of the Measurement Uncertainty Working Group was acknowledged in the most recent issue of Environmental Engineering, where editor William Kimberley reported an interview with the group on the editorial leader page.

Humidity (Spreadsheet)

Version 2.02, November 2007 Author :- R F Pragnell BSc, CEng, MInstMC, MSEE Copyright RF Pragnell, November 2007. The purpose of this spreadsheet is to provide the most commonly required hygrometric formulae as functions in Excel. Note: This Spreadsheet contains worked examples from the presentation at the Cranfield climatic testing course.
