EN 55024 date of withdrawal set

Implementing Decision (EU) 2021/455 published March 16, 2021, has set the date of withdrawal of EN 55024 (immunity for Information Technology Equipment) to Sept. 16, 2022. EN 55024 has been superseded by EN 55035 (immunity for Multimedia Equipment).

This publication also sets the date of withdrawal for EN 55103-2 (immunity for Professional Entertainment Lighting and Control), to July 28, 2022.

The date of withdrawal of a European EN is the date by which all superseded standards are withdrawn and cease to give presumption of conformity.

ANSI C63.10 2020 Published


The American National Standard of Procedures for Compliance Testing of Unlicensed Wireless Devices, IEEE/ANSI C63.10 2020, has been published.

ANSI C63.10 is the U.S. consensus standard covering methods and instrumentation and test facilities requirements for measurement of radio frequency (RF) signals and noise emitted from unlicensed wireless devices (also called unlicensed transmitters, intentional radiators, and license-exempt transmitters) operating in the frequency range 9 kHz to 231 GHz.

At the time of this 2020 version publication, January 29, 2021, the version accepted by the FCC for wireless certification remains ANSI C63.10 2013, effective from July 13, 2016. The new version must first be incorporated by reference within the U.S. Code of Federal Regulations (CFR) Title 47, §2.910. Publication will often come with a reasonable transition period as defined in §2.950.

IEC 60601-1-2 Edition 4.1

September 2020, the EMC Standard for medical devices, IEC 60601-1-2 edition 4.1, has been published. Added to the FDA recognized consensus standards on December 21, 2020 with partial recognition. 

The FDA has designated a 3 year transition period, after which the previous version will not be accepted- REC#19-8 (IEC 60601-1-2:ed4.0 + ANSI AAMI IEC 60601-1-2:2014).

New testing requirements include 

  • Testing at minimum and maximum input voltage levels for conducted emissions and voltage dips and short interruptions
  • Power frequency magnetic field at either 50 or 60 Hz so long as the frequency is the same as that used to power the equipment
  • A new technical reference standard has been added IEC 61000-4-39:2017 
  • Magnetic field immunity testing requirements from 9 kHz to 13.56 MHz 
Some of the normative references have been updated to reflect new versions of older base standards updating requirements for emissions and surge and voltage dips. Removal of ISO 7137:1995 procedures for airborne equipment.

The standard includes guidance on the determination of immunity levels and adjustments according to implemented mitigations and intended use. Identification of pass/fail and guidance on risk management for basic safety and essential performance related to electromagnetic compatibility. 

FDA FR Recognition Number 19-36

Canada ICES-003 update

Innovation, Science, and Economic Development Canada (ISED) has published issue 7 of ICES-003. Following are the main changes as published in the standard.

1. Changed title of the standard from Information Technology Equipment (Including Digital Apparatus) — Limits and Methods of Measurement to Information Technology Equipment (including Digital Apparatus) 

2. Added requirements for devices with wireless power transfer functionality (section 1.3) 

3. Removed requirements that are specified in ICES-Gen and referred to ICES-Gen for all general requirements (section 2.2) 

4. Removed the alternative limits (ICES-003 now has only one set of limits), while continuing to allow either the CISPR or ANSI test methods (section 3)

FCC Publishes Addendum to draft for U-NII 6 GHz devices

The FCC has published an addendum to the draft U-NII 6 GHz certification guidance. The purpose of this document is to provide clarifications and updates to 987594 U-NII 6 GHz devices 5.925-7.125 GHz DR01-44057 during the commenting period. This addendum will evolve as the draft period continues, adding new items to the existing ones and incrementing the version.

A link to this addendum is here:

In a related post, in August 2020 the FCC published guidance for certification of 6GHz devices, see posting "FCC publishes guidance on certification of 6 GHz devices operating in the 5.925 - 7.125 GHz U-NII band" for a link to that guidance document.

These documents are in support of the the newly published, May 2020, FCC rules, effective July 27, 2020, opening more spectrum for unlicensed use in the 5 to 7 GHz range.  See "FCC Adopts Rules for Unlicensed Use of the 6 GHz Band"

FCC publishes guidance on certification of 6 GHz devices operating in the 5.925 - 7.125 GHz U-NII band

Following the adoption of new rules published in May, 2020 allowing use of new spectrum for emerging "6 GHz" devices, the Federal Communication Commission (FCC)  Office of Engineering and Technology (OET) Laboratory Division has published a draft guidance document for public review covering certification of U-NII 6 GHz devices operating in the 5.925-7.125 GHz band.

The document can be found on the FCC OET Page, a shortcut provided here -
