New presentation on PCM calorimetry compares RAL, IEA standards

Ben Welter - Thursday, April 13, 2017

Dr. Harald Mehling, an expert in thermal energy storage and a RAL Quality Association PCM consultant, has prepared a 37-minute presentation on phase change material calorimetry. It is intended for people starting to work in the field as well as for people who already have experience.

Dr. Harald MehlingThe presentation consists of three parts:

1. Introduction. Historic background and a general introduction to standards.

2. The RAL industry standard. Required data, resolution and accuracy; a survey of common measurement techniques; and results of an internal comparison test.

3. The International Energy Agency standard for research and development using differential scanning calorimetry, which is based on the RAL standard, including its background, the standard and achieved improvements.
