Inductive Wireless Charging Products Must Comply with These Emissions & SAR Requirements

power.480Manufacturers of new technologies often struggle to determine what electrical compliance regulations apply to their products.  Here is a basic guide for inductive wireless power products, like the wireless mobile phone chargers that are gaining more market penetration.

This post is derived from an Intel Corporation presentation given at the recent FCC TCB Council Workshop in Baltimore, MD.  As a leading FCC TCB, MET Labs attends this workshop annually.

With the merger last week of the Alliance for Wireless Power and the Power Matters Alliance into the new AirFuel Alliance, the inductive wireless power product industry has been reduced to two competing technologies. (Wireless Power Consortium, owner of the Qi wireless standard, controls the other one).  These two technologies sometimes vary in their compliance requirements, as noted below.

Emissions: 6.78 MHz Emissions: 100-400 KHz RF Exposure (SAR)
United States FCC Part 18 FCC Part 15C or Part 18 FCC Part 1.1310
Canada RSS 216 RSS 216, RSS gen or RSS 210 RSS 102
Europe EN 55011 EN 300 330 or EN 55011 1999/519/EC, ICNIRP
China MIIT No. 423, Type C MIIT No. 423, Type A or D No
Korea RRA Notice 2013-9 RRA Notice 2013-9 FCC Part 1.1310
Japan In development In development ICNIRP

 

In many of these markets, standards and regulations are in transition, so contact MET to determine the latest requirements.
