Ohio’s New Approach to Code Adoption – The Worst of Both Worlds

Ohio’s New Approach to Code Adoption – The Worst of Both Worlds

At its November 30, 2011 meeting, the Residential Construction Advisory Committee (RCAC) of the Ohio Board of Building Standards addressed the issue of code adoption cycles.  As has been a growing trend in the states, the Ohio Home Builders have been promoting the extension of the code adoption process from the typical three years to six years.  But in addition to doubling the time that the state would remain stagnant on a single code, it was also proposed that a code by amendable at Read more [...]
Impact of EMF Exposure Limits and MRI

Impact of EMF Exposure Limits and MRI

Articles, by Professor J.C. Lin of the University of Illinois in Chicago, highlighting ICNIRP’s role in establishing limits for EMF exposure during MRI procedures were published in IEEE periodicals Microwave Magazine, vol. 12, no. 4, pp. 46-56, June 2011, and in Antennas and Propagation Magazine, vol. 53, no. 1, pp. 169-174, Feb.2011.  The articles provide useful information but do not tell the whole story regarding low frequency exposure limits, specifically recognition of the work of Read more [...]

Calling all NEMA lithium-ion battery manufacturers

Calling all NEMA lithium-ion battery manufacturers

Now is the time for NEMA members in the lithium-ion battery industry to get involved in IEC nano standards work. Balloting of a new work proposal in IEC TC 113 is underway for electrochemical characterization of cathode nanomaterials for lithium-ion batteries. It’s crucial that US industry get involved now, through the IEC TC 113 US Technical Advisory Group. The future of renewable energy significantly depends on the development of efficient systems for energy storage and lithium-ion Read more [...]
