Terms of Reference

• SG 5 is responsible for studies related to
  electromagnetic compatibility (EMC) of
  telecommunication systems including to avoid
  hazard to human beings
• Lead SG for
• Area 0 Generic, Domain 15 ElectroMagnetic
  Compatibility (EMC), Protection and Safety

4
Highlights of achievements (I)

• SG 5s leadership on the management of
  electro-magnetic interference to
  telecommunication systems from power systems has
  been consolidated by
• New Recs. K.54 and K.68
• Revision of Volume V and VI of the Directives
  Protection of telecommunication lines against
  harmful effects from electric power and
  electrified railway lines

5
Highlights of achievements (II)

• SG 5s leadership on the standardization of
  equipment resistibility has been consolidated by
  
• Revision of Recs. K.20, K.21, K.44 and K.45
• as well on lightning protection of
  telecommunication systems by
• New Recs. K.67, K.71 and K.72
• Revision of Recs. K.46 and K.47

6
Highlights of achievements (III)

• In the field of human exposure to electromagnetic
  fields (EMFs)
• New Rec. K.70, together with associated EMF
  estimator software, gives guidance on mitigation
  methods for reducing the radiation level from
  radio-communication installations in order to
  comply with exposure limits
• Recs. K.52 and K.61 on EMFs calculation and
  measurement methods have been revised

7
Highlights of achievements (IV)

• In the Home Network field
• The new Rec. K.74 provides EMC, Resistibility
  and Safety requirements for home network devices
  that mainly have the function of
  telecommunication
• In the new Rec. K.75, Manufacturers, Network
  Operators and Test Houses can find classification
  of telecommunication equipment interfaces for the
  application of standards on resistibility and
  safety

8
Highlights of achievements (V)

• Protective Components characteristics are given
  in the new Recs. K.65 and K.69 and revision of
  Recs. K.12 and K.30
• The new Recs. K.66 and K.73 are in the field of
  Earthing and Bonding, whereas the new Rec. K.76
  and the revision of the Rec. K.48 are in the EMC
  field
• The deployment of broadband services has
  increased the risk of interference of wire-line
  telecommunication networks with radio services.
  The revision of Rec. K.60 deals with the
  management of this risk

9
Future Work (I)

• Continuation of Questions dealing with
• Home Network
• Security of telecommunication and information
  systems regarding electromagnetic environment
• EMC requirements for Information Society
• Interference on telecommunication systems from
  power systems
• Resistibility and Safety requirements

10
Future Work (II)

• Continuation of Questions dealing with
• Lightning protection of telecommunication
  installations
• Human Exposure to Electromagnetic fields from
  telecommunication installations
• Earthing and Bonding techniques
• EMC requirements for telecommunication equipment
