EMC list of harmonized standards update, new ITE standards

Image via Wikipedia

The list of standards for use under the EMC directive, 2004/108/EC, published in the Official Journal of the European Union has been updated.

Among the updates within the list are the inclusions of the 6th edition of the emissions, and 2nd edition of the immunity standards, for Information Technology Equipment (ITE), titled EN55022:2010 and EN55024:2010. These official titles are the modified version of CISPR 22:2008, and unmodified CISPR 24:2010.

The inclusion in the official journal is a prerequisite for a standard to be considered harmonized for use in the presumption of conformity with the essential requirements of a given directive. This allows these new standards to be used for compliance testing.

These new versions will supersede their predecessors on December 1st 2013, at which time they become mandatory. Any new product shipped into the European Union on or after December 1, 2013, must comply with the new ITE specifications.

An update on PLT, Power Line Telecommunications, in Europe.

Image by Manu_H via Flickr

Sometimes referred to as PLN (Power Line Networking), PLA (Power Line Adaptor), PLC(Power Line Carrier), or here in the US, BPL (Broadband over Power Line), the technology enables the distribution of digital communications through conventional power lines, making it easy to setup communications networks without the need to rewire, or use radio transmitters. As data rates of these devices increase, so does the potential for interference, thus much work is being done by stakeholders to develop uniform methods by which to assess products with this technology for compliance with the EMC directive, and prevent unwanted interference of incumbent services.

The CLC/ Technical Committee 210 on electromagnetic compatibility (or TC210) established a working group (WG11) to produce a two-part standard for emission requirements for PLT apparatus of all types, as follows:

EN 50XXX-1 Power line telecommunications modems - Radio disturbance characteristics – Limits and methods of measurement - Part 1: Modems for in-house networks

EN 50XXX-2 Power line telecommunications modems - Radio disturbance characteristics – Limits and methods of measurement - Part 2: Modems for access networks

A draft document for Part 1 has been prepared by TC210/WG11,

The document is being set for a 3 month enquiry under what is called the Unique Acceptance Procedure, or UAP, and then given over to WG 11 for update if necessary. After this, it will be issued for a 2 month vote.

Following is some background on the controversy over PLT.

Currently, no separate harmonized standard exists for testing PLT product specifically. Certain classes of PLT are incapable of complying with current emissions limits as is, thus; some manufacturers have been looking to EU Notified Bodies, some of which have been prescribing the use of alternative draft standards for testing purposes. Manufacturers have a couple of options for EMC compliance, one is a self certification, test and comply with harmonized standards and issue a declaration of such. A second method, when harmonized standards don’t exist or are not able to be applied, is to perform an EMC assessment and prepare a Technical Construction File, usually in consultation with a Notified Body, seeking the opinion of the Notified Body, to support claims of compliance with the essential requirements of the EMC directive. The bottom line however is that in the end, the product must comply with the essential requirements of the EMC directive, which is that, “the electromagnetic disturbance generated does not exceed the level above which radio and telecommunications equipment or other equipment cannot operate as intended”

An independent study, commissioned and published by Ofcom, the UK communications regulator responsible for enforcing aspects of the EMC regulations within the UK, was designed to examine the likelihood and extent of interference from PLT devices. This study was formed mainly due to claims that the use of PLC technology is disruptive to incumbent services, and, as a result, has attracted the attention of stakeholders, most notably, the amateur radio community and shortwave listeners.

As a result of this study, Ofcom advises that the conclusions indicate that the incorporation of mitigation techniques is important for the future of PLT technology. Ofcom expressed its concern that manufacturers should incorporate these features, to provide long term protection to the radio spectrum, and minimize potential for interference. The study can be found via Ofcom’s stakeholder web page

Controversy exists on whether mitigation techniques, such as smart notching or automatic level control go far enough to protect incumbent services. Real concern exists in the amateur radio community that many products on the market now do not implement mitigation techniques at all, and therefore are currently posing a problem for the amateur radio and shortwave listeners. The amateur radio community has been lobbying Ofcom, as the responsible authority for EMC enforcement within the UK, to remove such products from the marketplace. The Radio Society of Great Britain, or RSGB, has established a “Spectrum Defense Fund” to, as indicated in a Feb 2010 statement, “combat the threat of PLT/PLA”, as well as for the general protection of the spectrum for the amateur radio community.

ISN for ITE telecom line testing

Image by pascal.charest via Flickr

On November 11^th, 2009, the VCCI Council of Japan issued notice describing the restrictions on the use of Impedance Stabilization Network (ISN) to be used for the measurement of telecommunication ports conducted EMI. Although this information is published in the current CISPR standard, the VCCI Council will only begin to deal with the filing of reports on telecommunication port conducted emission from April 2010. Currently, a great deal of confusion abounds on the proper selection of the ISN for telecom measurements. This notice helps to clear up some of that confusion.

As implied, the document describes the acceptable types of ISN, suitable for the measurement of telecom line conducted EMI. Most notably, the document comes with warning notes about using certain types of ISNs with certain quantity of balanced pairs. Get a copy of the notice.

> 1GHz testing for Japan

Image by End of Summer via Flickr

It’s known for several months now, that the European Union has deferred implementation of EN55022:2006 +A1:2007 until October 2011.  But what about others that implement CISPR standards for EMC

EN55022 is the emissions specification for Information Technology Equipment, or ITE. It is a derivative if CISPR22. The A1:2007 amendment adds the requirement for testing from 1GHz to 18GHz, depending on the operating frequency of the product under test.

However, in Japan, the current Voluntary Control Council for Interference by Information Technology Equipment (VCCI Council) rules call for mandatory compliance with the CISPR 1GHz to 18GHz test band by October 2010. The news here is that, so that Japan can be harmonized with Europe and other countries, It has been presented at a meeting in London, that the intent of the VCCI is to defer the 1-18 GHz requirements until October 2011.

 

EN55022:1998, ITE Emissions Standard Extended for Two Years.

Image by Nick J Adams via Flickr

The European union published in the official journal today, a postponement of the cessation of presumption of conformity for EN55022:1998 with amendments A1 and A2.

The new date is set at October 1, 2011.

Essentially what this means is that EN55022:1998 and it amendments are valid for another two years, until 10/1/11, and that testing above 1 GHz will now be required in late 2011, instead of late 2010. With this extension, it is a real possibility that the requirements for above 1 GHz testing, as well as the site verification method can change significantly.

Several competing standards are on the horizon, one of which is a new standard for multimedia equipment CISPR 32 forecasted for publication by the IEC November 2010, which could potentially reduce the amount of product that falls within the scope of EN55022, and require significantly different test levels and methods.
