FCC Proposes Big Changes to Part 15 & 68 Electrical Equipment Approval Process

by admin on Mar.20, 2013, under EMC, Wireless

The U.S. Federal Communications Commission (FCC) has proposed important changes to its equipment testing and authorization program under Part 15 and Part 68 of its rules.  The FCC says the changes will streamline the approval process and expedite the introduction of new devices to the market.

In a Notice of Proposed Rulemaking issued last month, the FCC proposed a number of changes to its existing equipment authorization program. The key proposed changes include:

TCB Accreditation – Telecommunications certification bodies (TCBs) – like MET Labs – will be accredited in accordance with the requirements of ISO/IEC 17011 and ISO/IEC 17065. These standards replace ISO/IEC Guides 58, 61 and 65.

Testing Laboratories Accreditation – Laboratories that test equipment subject to certification or approval under any of its rules must be accredited to ISO/IEC 17025.

TCB Authority – The FCC will no longer directly issue any grants of equipment authorization. Instead, TCBs will authorize and deny all products subject to certification.

Post-Market Surveillance – For post-market surveillance, the FCC will specify the number and types of samples that a TCB must test.

Assessing TCB Performance – NIST will assess TCB performance. The Commission also outlined a process to address TCB non-performance issues.

Measurement Procedures – ANSI C63.10-2009 will be the procedure used to determine the compliance of intentional radiators, and ANSI C63.4-2009 will be the procedure for assessing unintentional radiators.

We understand these proposed changes are likely to go through without significant modification, but first there is a comment period to elicit feedback.  Comments on the Commission’s proposed rule changes are due by late March here.

TCB Workshop Includes R&TTE Directive Overview

by admin on Nov.03, 2011, under Telecom, Wireless

Last week, MET Labs attended the FCC Telecommunication Certification Body (TCB) Council TCB Workshop in Baltimore.  Here was the agenda.  

One of the workshop’s more interesting presentations was on the R&TTE Directive.  Following is a summary of the key points.

The Radio and Telecommunication Terminal Equipment Directive applies in Europe and the European Economic Area.

There is no certification for the R&TTE Directive 1999/5/EC.  Meeting the requirements is the responsibility of the manufacturer or whoever puts the device on the market.

  • Products must have CE mark to show compliance
  • Declaration of Conformity (DoC) must be created for each device
  • Technical Construction File (TCF) is necessary to demonstrate compliance

The CE mark must be visible on the label, user manual, and packaging, and must include the Notified Body and Alert Symbol, if applicable.

The DoC must be available in each language, and must be traceable to a signatory.

The TCF must be kept for at least 10 years after the final version of each device has been made.

R&TTE Directive does not give test limits.  It instructs the manufacturer that the device must comply with certain performance requirements:

  • Article 3.1a – Health (RF exposure; boundary calculations; acoustic safety; typical operation)
  • Article 3.1a – Safety (EN 60950 for IT equipment; EN 60065 for Audio/Video equipment)
  • Article 3.1b – EMC Performance (EN 301 489 series for radio; EN 55022 & EN 55024 for TTE)
  • Article 3.2 – Radio Spectrum (output power; frequency tolerance; spurious emissions; receiver performance tests; tests at extreme voltage/temperature)

R&TTE Directive divides products into two classes:

  • Class 1 – No restrictions on putting the device into service
  • Class 2 – Restrictions exist for use of the device, and Country Notifications may be necessary

Ideally, all devices fall within an existing harmonized (harmonised) test standard.  If you test to a harmonized standard and pass, there is a presumption of conformity to the essential technical requirements.

Harmonized standards are listed by the European Commission in its Official Journal (OJ).   

When a standard is superseded, the device should meet the new version of the standard to stay compliant.  There is an overlap period.

A Notified Body opinion is required if harmonized standards are not fully applied in these situations:

  • Device has new technology with no applicable standards yet
  • New standards are not yet harmonized
  • Family of products, where the standard has not been applied to some models
  • Test procedures or processes of the harmonized standard were not followed

If the technology is new and no harmonized standards exist, the manufacturer works with a Notified Body – like MET Laboratories – to determine a test plan, or parts of another standard to use.  Alternatively, use a new version of a standard which has not yet become harmonized.

For most Radio and Telecommunication Terminal devices, the R&TTE Directive alone is sufficient – the EMC and Safety (Low Voltage) Directives do not apply.

R&TTE Directive was written in 1999.  The new version of the directive is being written now, with these goals in mind:

  • Improve traceability to DoC signatory
  • Improve compliance rates
  • Improve process for dealing with non-compliant products
  • Maintain equipment quality
  • Maintain trade

The next TCB event is a FCC/TCB Conference Call on December 13.  The call is restricted to TCB personnel, but Associate Members can receive the call minutes.

TCB Workshop Includes Latest FCC Updates

by admin on Apr.27, 2011, under EMC, Telecom

Earlier this month, MET Labs attended the FCC Telecommunication Certification Body (TCB) Council TCB Workshop in Baltimore.  Here was the agenda

Some highlights from the workshop overview:

Equipment authorization certifications continue their upward trend, reaching nearly 12,000 in 2010.

98.5% of products were approved by TCBs, continuing the downward trend of TCB exclusions.

An increasing number of complex devices are creating new challenges, like additional Permit But Ask (PBA) requests (see below for the latest on PBA).

The first potential FCC ID revocation raised some questions on the process.

FCC identified complex products as a challenge for the equipment authorization program.  Following are their focus areas:

  • Continued updating of technical expertise of laboratory testers, reviewers, and assessors
  • Detailed review of operations descriptions
  • Challenges for timely review considering volume of applications
