Watch our latest Webinar: CE Marking, What is it?



This presentation presented by TÜV SÜD Product Service is intended to provide a practical approach guide to what you need to know about the CE marking requirements for electrical and electronic equipment placed on the European Market. The material is intended to inform those that do not already understand CE marking requirements and to clarify and reinforce the understanding of those already familiar with the concepts.

I have been told that my product falls within the scope of the R&TTE Directive but what do I need to do with respect to EMC?


Your product will therefore be tested against the requirements of the R&TTE Directive. The R&TTE Directive applies to all radio equipment and to telecommunications terminal equipment intended to be connected to public telecommunications networks.

The R&TTE Directives essential requirements do however call up the requirements of the EMC and Low Voltage Directives so there is no requirement to address these Directives separately. Therefore the EMC requirements for the R&TTE Directive will by completed by following the route to compliance from the presentation.

Do fixed installations such as large test rigs require re-assessment if factory equipment is subsequently relocated?


A risk assessment will need to be made as to whether the new environment is the 'same' as the old. Different precautions may be needed in the new location for example, the equipment's new installed position may be at a location where the boundary of the fixed installation is closer to houses etc. Further in-situ testing may be required if technical rationale cannot be produced.

What is the interaction between RTTE products and Marine Products?


The RTTED covers products that are used in Non-SOLAS vessels. Equipment intended for use in SOLAS vessels fall under the Marine Equipment Directive. This can be the same equipment and so the manufacture must make clear in their “Intended Purpose Declaration” that the product is intended for use in either Non-SOLAS or SOLAS vessels.

If you meet the R&TTE Directive, do you still need to meet the EMC Directive?


No the RTTE covers the EMC aspects of the products. The only exception to this is when the product is a “wireline” product then the LVD and EMC Directives can be applied separately if desired.
Do products intend for use in a car fall under the R&TTED or Automotive Directive?

Products built into a car must have the Automotive Directive applied as well. Products that are occasionally used in a vehicle on a car charger can follow the RTTED alone. However if an RTTE product is intended for use in a vehicle then information should be included in the user manual to ensure it’s safe installation and usage. Alan Binks Page 3 of 5 1st March 2010.

TÜV SÜD Product service is hosting a complimentary Ethical Trade Seminar on 12th May 2011.

Come and join TÜV SÜD Product service at the Hilton London Metropole on Thursday 12th May 2011 for a complimentary seminar on Ethical Trading and Due Diligence for Importers and Retailers, presented by Ethical Trade Specialist Muriel Johnson and TÜV SÜD expert Richard Poate.

This seminar is an event not to be missed as it will provide you with up to date information on Ethical Trading, including the code landscape, sharing challenges by country and providing you with a framework for a risk base opportunities, presented by Muriel Johnson an Ethical trade specialist, who will share his knowledge and experiences from 'learning the hard way'.  Along with Muriel, Richard Poate will be presenting on Due Diligence, 'Start compliant, Keep compliant', which will include the importance of Due Diligence for importers and retailers.
The day is due to start at 9.00 am and run until 12.30 pm.

If you would like to attend or would like more information then please call +44 (0)1489 558224 or alternatively email Zoe Perkins on zperkins@tuvps.co.uk

Do passive RFID tags fall under the RTTE Directive and require to be CE Marked?


Both readers and transponders shall bear the CE marking. In the case of small, passive transponders1 supplied independently of readers, it may be appropriate to apply the CE marking to packaging rather than the transponder itself. In all cases, appropriate user information should be supplied. In the case of small, passive transponders supplied independently of readers the user information may be provided with each batch of transponders delivered to the supplier using them for stock identification etc. For the purposes of Article 6.3 of the R&TTE Directive, the supplier of the product incorporating the transponder or to which the transponder is attached shall be regarded as the user of the transponder and not the eventual purchaser of the product itself.

Design for EMC Training Course

Dates: 17th- 19th May 2011 & 13th - 15th SeptemberCost: £690 Booking fee for 17th - 19th May and £690 (If you book  09/08/2011 for the September course) or £750 after.Time: 9am - 5pm, 3 day courseLocation: Octagon House, Fareham, Hampshire P015 5RL

Description

This course will cover design to meet the compliance requirements of the European EMC Directive, as well as other commercial and military requirements. Good EMC design gives you a product that is more reliable and better fitted for its environment. The course is structured to achieve the maximum learning potential from a combination of tutorial and case study exercises. It emphasises the underlying physics of interference generation and coupling and how it affects design methods, without resorting to complex mathematics.

 

Who should attend

Electronic product designers and design managers: a basic knowledge of electronics is assumed. The course will be of particular interest to design engineers in industrial, medical, transport, telecomms, IT, consumer, marine and military sectors who have to meet EMC requirements as part of their project specification. It will help them deal with the technical and compliance aspects of EMC, as well as avoiding EMC-related design mistakes that disrupt project timescales and budgets.

Programme

Day 1 – introduction and theory
  • Introduction to EMC; IEC, EN and MIL test standards
  • Why EMC? – the definition of EMC – the various phenomena – the product life cycle and reliability aspects – the EMC and R&TTE Directives – other Directives – military and aerospace requirements
  • The standards regime – standards generating bodies – military/aerospace versus commercial – content of the most common test standards
  • Principles of interference coupling
  • Using the dB – frequency versus time domain – coupling modes – electric, magnetic and electromagnetic fields – transmission lines – general emissions and immunity control

  • System partitioning – ground as a current return path – control of loop area – current flow in a ground plane and a shield surface – the effect of slots and apertures – conductor impedance and bonding – partitioning the circuit from the interface
  • Case study: current paths in ESD and EFT events
Day 2 – Mechanical, PCB and cables
  • PCB layout
  • Grounding and track impedance – proximity of return path – gridded and ground plane layouts – the optimum ground plane – on-board shielding – interface layout and grounding – layer stack-up
  • Cables and connectors
  • Mode of propagation – unscreened cables: twisted pair, ribbon – cable balance and LCL – screened cables: screen operation, transfer impedance – the effect of the connector – cable installation
  • Shielding
  •  Theory of reflection and absorption – effect of apertures and seams – conductive gaskets – conductive coatings and shielded windows – partitioning shielded enclosures – using the shield as ground – cable layout and large enclosures
  • Exercise and case study – mechanical, PCB and cable design review
Day 3 – Electronics
  • Digital and analogue circuit design
  • Emissions from digital circuits: clocks, transmission line ringing, decoupling, using single chip micros, using complex microprocessors – emissions from analogue circuits: unanticipated oscillations, video signals – logic circuit immunity: timing and logic threshold constraints, transient susceptibility, defensive programming – analogue circuit immunity: bandwidth, linearity and dynamic range, balance, isolation
  •  Power switching circuits
  • Emissions from switching circuits – coupling paths – differential and common mode conducted – radiated – construction techniques: screens, transformers
