The International Electrotechnical Commission (IEC) has ratified a new standard–ISO/IEC 14543-3-10–for wireless applications with ultra-low power consumption pioneered by EnOcean. The standard can be downloaded from
www.iso.org.
The new standard is geared to wireless sensors and wireless sensor networks with ultra-low power consumption. It also includes sensor networks that utilize energy harvesting technology to draw energy from their surroundings–for example, from motion, light or temperature differences. This principle enables electronic control systems to be used that work independently of an external power supply.
Specifically, it covers OSI (Open Systems Interconnection) layers 1-3, being the physical, data link and networking layers. The full title of the standard is: ISO/IEC 14543-3-10 Information technology–Home Electronic Systems (HES)–Part 3-10: Wireless Short-Packet (WSP) protocol optimized for energy harvesting–Architecture and lower layer protocols.
International standardization will accelerate the development and implementation of energy-optimized wireless sensors and wireless sensor networks. It will also open up new markets and areas of application for energy harvesting solutions. In addition to the already established markets for home and building technology, there will be further uses ranging from the smart home, smart metering and the smart grid to solutions for industry, logistics and transport.
Members of the EnOcean Alliance have already introduced more than 850 EnOcean-based, interoperable products, all of which comply with the new standard. Developers and manufacturers can therefore benefit from the Alliance’s extensive practical experience, huge product range and installed base, and many years of user education.

The National Electrical Manufacturers Association (NEMA) has published NEMA WD 7 Occupancy Motion Sensors Standard.
Previously published as a guide and not a standard, WD 7 promotes uniformity for the definition and measurement of characteristics relevant to the use and application of occupancy motion sensors. This standard covers the definition and measurement of field of view and coverage characteristics relevant to the use and application of vacancy and occupancy sensors using individual or any combination of passive infrared, ultrasonic, or microwave technology. These sensors are used in systems for control of lighting, heating, ventilating, and air conditioning (HVAC), and other devices.

The
National Electrical Manufacturers Association (NEMA) has published NEMA 410-2011 Performance Testing for Lighting Controls and Switching Devices with Electronic Drivers and Discharge Ballasts. This standard, last published in 2004, is maintained by the association’s Lamp, Ballast, Lighting Controls, and Wiring Device sections.
NEMA 410 provides guidance for the design and testing of lighting controls and switching devices to be used with electronic drivers, discharge ballasts, and self-ballasted lamps to assist in establishing and verifying compatibility between products. This standard has been expanded to encompass additional types of lighting technology, and numerous figures and test circuit diagrams and designs have been added.
Ed Thomas of GE Lighting, chair of the Ballast Section Technical Committee, said, “NEMA 410 is the industry standard for electronic ballast inrush current. This revision extends its applicability to include self-ballasted compact fluorescent lamps and integrated LED lamps, and NEMA encourages the standard’s use by those evaluating and designing electronic ballasts and device drivers.”
