PCM briefing: New RAL quality mark approved; Alexium working on undergarment for auto racing

Ben Welter - Monday, April 17, 2017

RAL Quality Mark• The RAL Quality Association PCM, established in 2004 to develop standards for the phase change materials industry, has received RAL approval to use a English-language version of its quality mark. The mark signifies that a PCM has met the association's quality and testing specifications (RAL-GZ 896) for PCM and PCM composites, objects and systems. 

Alexium International has announced plans to work with Benwel Inc. to introduce a fire-retardant undergarment for the auto racing industry. The undergarment will be treated with Alexiflam and Alexicool, Alexium's PCM-based cooling technology. 

Sonoco ThermoSafe is expanding its line of temperature-controlled pallet solutions with the launch of the LD7 Half PAG pallet shipper. The Half PAG is available for 2-8° C or 15-25° C temperature ranges with durations in excess of five days.

• The inaugural Chemical Watch Expo, REACH into the Future, will be held in Berlin April 25-26. The expo offers workshops on preparation for the REACH 2018 registration deadline.

AkzoNobel, Advanced Biochemical Co. and Ernst & Young are developing a new online tool to track the use of bio-based raw materials in products. The project partners say it will be the first tool to use e-certification to track bio-based content along the value chain. Initially the tool is focused on epoxy-derived products and coatings. AkzoNobel says more products and companies will be added later this year.

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.

The video is available for download at www.pcm-ral.org/pcm/en/quality-association-pcm/consultants/harald-mehling/ and can be viewed on Vimeo as well.

Forum on Germany's VDI 2164 guidelines set for June 20 in Düsseldorf

Ben Welter - Monday, April 03, 2017

Several members of the RAL Quality Association PCM will present lectures at the Expert Forum for VDI Guideline 2164, set for June 20 in Düsseldorf. 

The Association of German Engineers' building and building technology group (Verein Deutscher Ingenieure, or VDI) will host the meeting. VDI Guideline 2164 defines the fundamentals for latent-heat storage systems in buildings. 

Dr. Bernd Boiting, chairman of the VDI 2164 committee, will present a brief overview of the guidelines. Other speakers include Esther Kieseritzky of Rubitherm; Marco Schmidt of BASF and Stefan Thomann, managing director of the quality association. The complete agenda will be available in a few weeks.

Sunamp joins RAL Quality Association PCM

Ben Welter - Monday, February 13, 2017

Sunamp Ltd. of Scotland has joined the RAL Quality Association PCM, a European-based organization established in 2004 to develop standards for the phase change material industry. 

"Sunamp is delighted to join RAL PCM, the world's leading quality association for phase change materials," said Sunamp CEO Andrew Bissell. "We have extremely stable and long-lived, high energy density PCM that we deliver in high-power heat batteries. We look forward to working with RAL PCM and the other members to further develop PCM and Heat Battery standards, and to have our products certified."

RAL PCM has two key objectives: Promote the use of high-quality PCMs and influence the political landscape in the European Union in favor of PCMs. Other RAL members are Croda, BASF, Rubitherm, EMCO, va-Q-tec, PCM Technology, Global Energy Systems Europe, Sasol, Pluss Advanced Technologies and Entropy Solutions.

Association of German Engineers to publish PCM building technology guidelines this fall

Ben Welter - Friday, May 06, 2016

The Association of German Engineers committee responsible for developing guidelines on PCM storage systems in building technology (VDI 2164, PCM-Energiespeichersysteme in der Gebäudetechnik) is expected to complete its work this month, with publication in the fall.
 
The guidelines define the fundamentals of using latent heat storage materials in heating, cooling, ventilation and thermal energy storage systems. The guidelines also define the basics of PCM storage systems and provide planning and calculation methods for proper design and their performance parameters.
 
The guidelines, which are not legally binding, can be seen as “reassurance for experts that they are in line with the recognized state of the art technology,” according to Stefan Thomann, managing director of the RAL Quality Association PCM, a European-based organization established in 2004 to develop standards for the phase change material industry.
 
Dr. Bernd BoitingThe Association of German Engineers (Verein Deutscher Ingenieure, or VDI) and Deutscher Industrieverlag will host their first joint congress for technical building equipment in Baden-Baden, Germany, Nov. 29-30. Dr. Bernd Boiting, right, president of the PCM quality association and chairman of the VDI 2164 committee, will give a lecture about PCM storage systems and the new guidelines.

The congress is expected to attract 500 or more participants. The complete agenda, along with contact information, is likely to be available in June.
