On October 02, 2014, the Department of Energy (DOE) proposed revising the testing procedure for external power supplies. The modifications considered are as follows:

Harmonize DOE's test procedure with the latest version of IEC 62301 by providing specific resolution and measurement tolerances.

  • Define and clarify how to test adaptive EPSs (also referred to as "adaptive-charging", "smart-charging" or "quick-charging" EPSs).
  • Add test configurations that can be used to avoid potential losses caused by testing cables.
  • Clarify that when testing an EPS that is incapable of being tested at one or more of the loading conditions used to calculate the average active-mode efficiency, such conditions will be omitted when calculating this metric. Instead, the average active-mode efficiency will be determined by averaging the efficiency results at each of the loading conditions that can be measured.
  • Optional test to measure the active mode efficiency at a 10% loading condition.
  • Optional recording of power factor during testing.
  • Insert a summary table (see Table) to enable one to more readily identify which standards apply to which type of EPS.
  • Expand the scope of its sampling plan for Class A EPSs to apply to those that will be subject to standards for the first time in 2016.

On October 9, 2014, Industry Canada posted on its website the release of Radio Standards Specification RSS-199, Issue 2: Broadband Radio Service (BRS) Equipment Operating in the Band 2500-2690 MHz, which sets out the certification requirements for BRS radio transmitters and receivers in the band 2500-2690 MHz. RSS-199, Issue 2 replaces RSS-199, Issue 1 (January 2010) and the following changes are listed below:

  • The equipment's unwanted emission mask is modified.
  • The method used to measure the equipment's frequency stability is added.
  • The compliance requirement for equipment with multiple antennas is added.
  • The requirement for receiver standard spurious emissions has been withdrawn following decisions made under Regulatory Standards Notice 2012-DRS0126.

On September 30, 2014, the FCC proposed modifications to its Part 15 rules that allow unlicensed spectrum use in white spaces between TV stations. The proposed changes to the rule would help facilitate the use of television bands, 600 MHz guard bands and channel 37. The band plan adopted for the upcoming 600 MHz incentive auctions, scheduled for 2015, built in opportunities for white space use in the guard bands and channel 37. The FCC hopes the revised rules will promote more efficient use of TV white space while protecting incumbents from interference.

The FCC has scheduled an Open Meeting on the subjects listed below for Friday, October 17, 2014. The meeting is scheduled to begin at 10:30 a.m. (Room TW-C305, at 445 12th Street, W., Washington, D.C.).  Additionally, the meeting will be shown live at FCC.gov/live

  • Spectrum Frontiers NOI:

The FCC will consider a Notice of Inquiry to explore innovative developments in the use of spectrum above 24 GHz for mobile wireless services, and how the FCC can facilitate the development and deployment of those technologies.

  • Wireless Infrastructure Report and Order:

The FCC will consider a Report and Order that takes critical steps to promote the deployment of wireless infrastructure necessary to provide the public with ubiquitous, advanced wireless broadband services.

  • Aggregate Interference and Inter-Service Interference Second Report and Order and Further Notice of Proposed Rulemaking:

The FCC will consider a proceeding to address aggregate broadcaster-to-broadcaster interference and the methodology for predicting interference between broadcast and wireless operations in the same or adjacent channels in nearby markets during and following the Incentive Auction.

  • Digital Low Power Television Third NPRM and Suspension Public Notice:

The FCC will consider a Notice of Proposed Rulemaking regarding measures to facilitate the final conversion of low power TV and TV translator stations to digital service, and mitigating the potential impact of the incentive auction and the repacking process. The FCC will also consider a concurrent Public Notice suspending expiration dates and construction deadlines for all outstanding unexpired construction permits for new digital low power television and TV translator stations.

  • 911 Outage Presentation:

The FCC will hear a presentation regarding an inquiry into a major 911 service outage that affected seven states in April 2014. The presentation will include findings from a report on the causes and effects of the outage as well as recommendations on actions the industry, the Commission and state governments can take to strengthen the reliability and resiliency of 911 services as the nation transitions to Next Generation 911.

 

EN 61326-1:2013, the revised EMC standard for measurement, control and laboratory use will go into effect on August 14, 2015. Basic updates were made to the standard as well as the following new requirements were added:

  • Technical changes were made for the equipment under the "basic environment" requirements in table.
  • The air discharge ESD test level has been increased from 4KV to 8KV.
  • A requirement for immunity to magnetic fields according to IEC 61000‐4‐8 was added but only for susceptible devices.
  • Additional details were added to the performance criteria for the immunity testing.
  • New requirements for the user manual were added.

As of September 19, 2014, a new standard, NOM-032-ENER-2013, went into effect and sets out the maximum electrical power limits for equipment and appliances requiring stand-by power.  The standard does not apply to equipment that is within the scope of existing norms for energy efficiency.  Additionally, it may not apply to highly specialized devices not intended to be sold directly to the public, or devices with a weight greater than 33 lbs. Local tests are required for certification.

In mid-September 2014, the Australian Communications and Media Authority (the ACMA) released the Radiocommunications (Compliance Labelling – Devices) Notice 2014(the 2014 Notice). The 2014 Notice revokes and replaces the Radiocommunications Devices (Compliance Labelling) Notice 2003 (the 2003 Labelling Notice) without making any significant changes to the regulatory arrangements created by the 2003 Labelling Notice.

The ACMA created the 2014 Notice as the 2003 Labelling Notice was due to "sunset" (i.e. be automatically repealed) on April 1, 2015, in accordance with Part 6 of the Legislative Instruments Act 2003 (the LIA).
