FCC Issues Draft Revisions for RF Exposure & SAR Compliance

by admin on Apr.30, 2012, under SAR, Wireless

The U.S. Federal Communications Commission (FCC) has issued draft revisions to six Knowledge Database (KDB) publications for RF exposure and SAR compliance.

They are:

KDB Publication 447498 – General RF Exposure Policies for Equipment Authorization

KDB Publication 941225 – SAR Evaluation Considerations for LTE Devices

KDB Publication 865664 – SAR Measurement Requirements, Compliance Reporting and Documentation for 100 MHz – 6 GHz

KDB Publication 616217 – SAR Evaluation Considerations for Laptop, Notebook, Netbook and Tablet Computers

KDB Publication 648474 – SAR Evaluation Considerations for Handsets with Multiple Transmitters and Antennas

KDB Publication 643646 – RF Exposure Evaluation Considerations for Occupational Push-to-Talk Two-Way Radios

The public may post a comment on these proposed revisions through June 1, 2012.

Other RF Exposure KDBs
Remaining RF exposure KDB publications that do not have draft revisions are:

  • KDB Publication 248227 – Additional SAR Measurement Procedures that Specifically Address 802.11 a/b/g Devices
  • KDB Publication 615223 – SAR Requirements and Procedures for 802.16e/WiMax Devices
  • KDB Publication 450824 – SAR Probe Calibration and System Verification Considerations for Measurements from 150 MHz to 3 GHz
  • KDB Publication 680106 – Rules Regulating Short Distance Wireless Inductive Coupled Charging Pads or Charging Devices

Questions about SAR compliance? A SAR testing expert will be available next week at 2012 International CTIA Wireless at the MET Labs exhibit.

ENERGY STAR Merges Lighting Scopes into New Luminaires & Lamps Specifications

by admin on Apr.19, 2012, under ENERGY STAR

Although this year marks the 20th anniversary of the ENERGY STAR program, lighting was a bit late to the party.  It wasn’t until 15 years ago that residential light fixtures got their first ENERGY STAR specification, and 13 years ago that compact fluorescent light bulbs (CFLs) did.

ENERGY STAR lighting continues to evolve.  Following are some updates.

Luminaires
The Luminaires Version 1.1 specification became effective April 1, 2012.  It combines the scope of the Solid-State Lighting (SSL) Version 1.3 specification and the Residential Light Fixtures Version 4.2 specification.

Only those light fixture models that have been third-party certified as meeting the Luminaires V1.1 requirements now appear on the ENERGY STAR qualified product list. Fixtures qualified under the previous specifications will not be “grandfathered in” to this new specification.

There are nearly 500 qualified luminaires from more than 50 manufacturers, covering over 20 different product types.

Lamps
The new ENERGY STAR Lamps V1.0 specification is still being developed.  This new specification will merge the scope of the Compact Fluorescent Lamps V4.3 and Integral LED Lamps V1.4 specifications into one technology-neutral specification. 

For draft 1 of the Lamps specification, EPA received 175 pages of comments. These comments are being considered for draft 2, which is anticipated in the next several months.

Certification Bodies
Using the new third party certification (3PC) process, in 2011 Certification Bodies like MET Labs certified 191 CFLs, 357 LED lamps, 166 luminaires, and 1,462 light strings.  In 2012, the number of lighting products certified is expected to be even higher.

According to EPA research, CB processing time ranges from 24 hours to two weeks, depending on a certification body’s work load and the completeness of a product submission.

Once a CB certifies a product meets an ENERGY STAR specification, it sends the data to EPA to be uploaded to the qualified products lists (QPLs).  Lists are currently updated weekly for bulbs and twice a month for fixtures (around the first and the middle of the month). By the end of 2012, all product lists should be updated on a daily basis.

Upcoming Events
The next ENERGY STAR products partner meeting is October 22–24, 2012 in St. Paul, Minnesota.  This is for lighting, as well as appliance and electronics partners and other stakeholders.

EPA Program Manager for ENERGY STAR Eamon Monahan will be speaking at MET Labs’ Annual Global Product Compliance Seminar & Crab Feast  in September.

CE Compliance Testing Delays Launch of Raspberry Pi Mini PC

by admin on Apr.10, 2012, under EMC, Europe

The recent delay in the high-profile new product launch of the Raspberry Pi has reminded electronics manufacturers of a simple truth: Compliance sometimes means exceeding regulatory requirements due to buyer demands.

The iPhone-size Pi is a $25 mini PC that is intended to teach students about programming.  Its maker, the UK-based Raspberry Pi Foundation, had been operating under the assumption that this type of engineering sample product could be sold in the UK without a CE mark.  After all, the rival ARM-based Beagleboard development kit is sold under the same terms without a CE mark, as are the majority of similar prototyping platforms.

The rub here is that the Pi has proved wildly popular, making its distributors nervous about lawsuits.  Distribution partners element14/PremierFarnell and RS Components insisted that the device receive a CE mark to indicate compliance with electronic emissions guidelines.  Their judgment was seconded by the UK Department for Business, Innovation and Skills (BIS), which said the Pi did in fact need to carry the CE marking.

Last week, to everyone’s relief, the Pi passed EMC testing without requiring any hardware modifications.  The testing was conducted at Panasonic’s facility in South Wales.

The device passed radiated and conducted emissions and immunity tests in a variety of configurations, as well as electrostatic discharge (ESD) testing.  In the lab for all of last week, the Pi is now also reportedly compliant with requirements for United States’ FCC, Australia’s C-Tick, and Canada’s Technical Acceptance Certificate.

KCC & MKE Change EMC, SAR & Product Safety Regulations in South Korea

by admin on Apr.02, 2012, under Korea

Following are recent and near future changes to electrical product regulatory requirements in South Korea.

Effective January 1, 2012, the Korean Communications Commission (KCC) requires radiated emission measurements at the limit, above 1GHz, by the highest internal source of the device and also conducted disturbance testing for devices with telecommunication ports. The limit is the same as CISPR 22:2006.

Effective July 1, 2012, the Ministry of Knowledge Economy (MKE) will assume responsibility for regulating safety of electrical products sold in Korea, a role currently carried out by KCC.  After July 1, KCC will only regulate IT/RF/Telecom products.

Effective January 1, 2013, KCC plans to expand its existing SAR requirements for mobile phones to include all radio equipment that is used within 20 cm of the human body. This harmonizes the Korean SAR requirements with FCC and other international standard requirements. Low powered radio devices (below 20mW) are exempt from this new requirement.
