2011 EMC Directory & Design Guide - Interference Technology

standards recap
common basic signals, built upon formal mathematical
specifications so that signals can be combined to form
complex signals usable across all test platforms.
IEEE 802.22.1-2010 — Information
Technology
Publication Date: Nov. 1, 2010
IEEE Standard for Information Technology--Telecommunications
and information exchange between systems--
Local and metropolitan area networks--Specific requirements
Part 22.1: Standard to Enhance Harmful Interference
Protection for Low-Power Licensed Devices Operating
in TV Broadcast Bands defines the protocol and data
formats for communication devices forming a beaconing
network that are used to protect low-power, licensed devices
operating in television broadcast bands from harmful
interference generated by license-exempt devices,
such as Wireless Regional Area Networks (WRAN),
intended to operate in the same bands. The devices being
protected are devices licensed as secondary under Title
47, Part 74, Subpart H in the USA and equivalent devices
in other regulatory domains.
IEEE to Develop Standard for Energy
Storage in Smart Grids
Publication Date: Jan. 13, 2011
A new project from IEEE will develop guidelines to
help facilitate the wide-scale and consistent implementation
of energy storage systems to support the power
infrastructure of the smart grid. The project, IEEE
P2032.2, “Guide for the Interoperability of Energy Storage
Systems Integrated with the Electric Power Infrastructure,”
is being developed by the IEEE Standards
Association Standards Board and its SCC21 - Fuel Cells,
Photovoltaics, Dispersed Generation, and Energy Storage
Committee.
Updated Standard Covers Analog-to-
Digital Converters
Publication Date: Jan. 14, 2011
The IEEE 1241 standard covering analog-to-digital
converters has been updated to address conflicts with
other standards. IEEE 1241-2010, “IEEE Standard for
Terminology and Test Methods for Analog-to-Digital
Converters,” incorporates many corrections and new
information. It also contains revised language that is
more consistent with IEEE 1057 and other standards.
IEEE 1241 provides common terminology and test methods
for the testing and evaluation of analog-to-digital
converters.
IEEE 1036 — First Revision to Shunt
Power Capacitors Guide
Publication Date: Jan. 17, 2011
IEEE has published a revision to IEEE 1036, “IEEE
Guide for Application of Shunt Power Capacitors.” This
is the first revision to the standard since 1992. IEEE 1036
applies to the use of 50 and 60 Hz shunt power capacitors
rated 2400 Vac and above, and assemblies of capacitors.
It includes guidelines for the application, protection, and
ratings of equipment for the safe and reliable utilization
of shunt power capacitors. The guide also covers applications
that range from simple unit utilization to complex
bank situations.
IEEE EMC Society Withdraws From
Power Line Communications Committee
Citing concerns about parts of its technical content,
the IEEE EMC Society Standards Development Committee
(SDCom) voted to withdraw as the cosponsor of IEEE
Standard for Power Line Communication Equipment
-- Electromagnetic Compatibility (EMC) Requirements
-- Testing and Measurement Methods (IEEE Standard
1775-2010).
VCCI Council
Japan VCCI: Compliance with Limits on
Radiated Disturbance Above 1GHz
VCCI Council will start enforcement of conformity
with limits on radiated disturbance above 1GHz of
products subject to conformity verification report filing
on and after Oct. 1, 2010. However, it is up to each member
to decide if he will opt in conformity assessment tests
above 1GHz until September 2011.
Nevertheless, however, let us ask you to positively
go ahead and ship products conforming to the 1GHz+
requirement by filing conformity verification reports on
and after October 1, 2010 as if there were no 1-year grace
period because VCCI runs its operation based on CISPR
standards transposed to Japanese standard by the Information
and Communication Committee, and July 2007
Japanese standard says implementation of 1GHz+ should
start in 2010.

European Union nations agreed on the need to
develop a standardized system for recharging electric
cars throughout Europe by next year. The union’s 27
industry ministers, meeting in Brussels in May, said the
standardization is important for a number of reasons,
