Are You RED-dy?

Come next summer, there’s a new song playing in Europe and if you want to tune in your radio products, you’ll have to go RED. June 12, 2017 is the magic date. (Reader caution: If you’re just getting into this topic, be ready for a barrage of acronyms…)

Radio Equipment Directive

The European Commission overhauled the requirements for radio devices, i.e., transmitters, receivers and transceivers back in 2014; but work on this began on the changes many years before that. The transition to the new Radio Equipment Directive 2014/53/EU will be complete, sort of, by June 13, 2017. Effective that date, transmitters, receivers and transceivers used for radio communication or radio determination will have to comply with the new Directive—even legacy equipment that was approved under the outgoing R&TTE Directive 1999/5/EC.

How To Work Safely with High‑Voltage Test & Measurement Equipment

This white paper describes an alternative approach to calibrating high-voltage systems and provides meter and probe safety considerations and general guidance for safely operating high-voltage equipment.

Heads-up radio folks, that means you should start planning for this transition now, or risk being rejected at customs.

The problem is that the route to compliance is often very simple, or can become a little convoluted. This article details the reasons the time-honored self-declaration may not work for everyone, at least in the short to medium term. We also cover a route you can pursue that will let you use the new RED in advance of the June date.

What’s RED?

The following aspects of equipment compliance are covered by the RED:

Radio: Traditional spectrum matters, frequency, power and spurious emissions limitations that are meant to make sure the spectrum is well behaved. The specific language in the Directive1 that defines the scope is: “Equipment which intentionally emits or receives radio waves for the purpose of radio communication or radio-determination [and] makes systematic use of radio spectrum.”

Safety: Product safety, including electrical safety and RF exposure, primarily. RED references requirements equivalent to the Low Voltage Directive 2014/35/EU (LVD) and equipment must comply. However, manufacturers should not state compliance with the LVD.

EMC: RED references requirements equivalent to the EMC Directive 2014/30/EU. As with the LVD, one needs to comply with the requirements of EMC, but shan’t reference it on any Declaration of Conformity (DoC).

These essential requirements haven’t fundamentally changed from the R&TTE Directive. The RED was updated because “Directive 1999/5/EC of the European Parliament and of the Council (3) has been substantially amended several times. Since further amendments are to be made, it should be replaced in the interests of clarity.”

Several of these clarifications include:

  1. Terminal Equipment: Equipment that plugs into landlines, which was covered by the R&TTED, is not covered RED. That stuff all moves into the EMC and LV Directives.
  2. Receivers: There is language in the RED that states that a receiver “has a level of performance that allows it to operate as intended and protects it against the risk of harmful interference.”
  3. Data privacy: Radio equipment must be designed to protect against fraud and intrusion.
  4. Notification: Under the R&TTED, it was necessary to send notification letters to spectrum authorities if a frequency to be used wasn’t harmonized across all EU member states. This has been removed and the responsibility is now with the manufacturer to research such things, using tools like EFIS, or European Frequency Information System (efis.dk).
  5. Type Examination Certificate: Under the R&TTED an opinion was issued by something called a Notified Body. This has been changed to a Type Examination Certificate. More on that later (because this is where the thrust of this article points.)

The above clarifications are necessary updates and improves the process for conformance with the Directives. What has not been fully implemented are the standards that manufacturers need to reference when testing their devices.

This is the fly in the ointment.

At first glance, it may seem that the technical requirements really didn’t change all that much, so there would be no real design implications. However, the inclusion of terms like “efficient use of spectrum” has led to changes in the test cases needed to demonstrate compliance. Efficient use of spectrum can be demonstrated through good performance receivers and spectrum sharing transmitters. There are, therefore, testing implications to prove those operations. This has led to significant changes to the test standards. However, very few standards have, to-date, been enacted for manufacturers to follow.

Wherefore Art Thou ENs?

The usual route for manufacturers since the beginning of the New Approach during the halcyon 1990s has been self-declaration to the Directive, by applying “Harmonized Standards” or ENs. These are standards that apply to specific equipment and everyone2 agrees are reasonable to prove conformity. That is, if a manufacturer applies the correct ENs, then a simple self-declaration and one is finished.

In the dynamic world of CE, the standards that are used for the “presumption of conformity” are listed in the public domain in the Official Journal of the European Commission (OJ). With the advent of the RED, many ENs have not yet been updated and added to the OJ for compliance. No ENs, no self-declaration, no CE.

So what’s a good radio manufacturer to do? This is where the role of the Notified Bodies (NBs) comes in.

Notified Whom?

Whilst updating the requirements for Radio Devices, the Commission also raised the bar for something called “Notified Bodies.” NBs are private-sector organizations that have been blessed by their respective countries to approve equipment under the EU system.

Under the RED, organizations who wish to have this designation must be accredited under either ISO 17065 or ISO 17020. This process is a formal audit program carried out by Accreditation Bodies (ABs) that are designated, I suppose that’s the word, by National Authorities in each member state or MRA country.

The National Institute for Standards and Technology (NIST) is the go-to in the US. NIST also deals with conformity assessment aspects under Mutual Recognition Arrangements. Under the US-EU MRA—more alphabet soup—US organizations that meet certain criteria enjoy the same status as European Notified Bodies (for a related article dealing with MRA issues, refer to In Compliance Magazine from July 20163.)

Now, back to the dilemma of the manufacturer.

Type Examination Certificate to the Rescue

The RED requires the CE Marking. One should use Harmonized Standards (HSs) where they are available. In cases where the applicable HS does not exist, the RED requires that a Notified Body issue a Type Examination Certificate.

It’s simple really. Under the structure, the NBs have the demonstrated competence and expertise to review the product, reference standards that would reasonably apply and issue the certificate. The Notified Body is basically stating that the device does meet the requirements of the RED, even though full testing to harmonized EN standards was not performed.

The review that proceeds would look at the available standards in the environment, including draft standards that are published, drafts that may not be published, and committee drafts that are in-process and may not be published. So it’s a bit of legwork for the NB.

The process goes in a flow as shown in Figure 1.

The output is a Type Examination Certificate that must include some specific information, namely:

“Name and address of the manufacturer, the conclusions of the examination, the aspects of the essential requirements covered by the examination, the conditions (if any) for its validity and the necessary data for identification of the assessed type. The EU-type examination certificate may have one or more annexes attached.”

Typically, a Type Examination Certificate will reference the standards used for assessment, the test reports and other technical documentation used for the review and specifics on the operating frequencies and output powers and modulations that the radio will use.

(Note that applying ENs that are listed in the OJ for the R&TTED is not allowed in most cases, as the technical requirements have changed. To apply a harmonized EN, it must be an EN which is listed in the OJ for the RED, not the R&TTED. If a type examination certificate is used, the Notified Body will be looking for the product to meet the RE Directive through testing equivalent to those new RED standards, including the additional receiver and spectrum sharing tests; and not to just rubber-stamp an upgrade to your old R&TTE test reports.)

Summary

June 12, 2017 will come quickly, so if you’re dealing radios to the EU, it is time to map out a compliance strategy that will keep the door open. It is not possible to guarantee that all the work to place Harmonized Standards into the OJ will be finished in time. In fact there are specific standards that have been announced “won’t be ready.” That’s just the reality.
