Working Party 1/5 – Damage prevention and safety
Working Party 1 made significant progress on its Work Programme and achieved the following key outcomes:
Consented revised Recommendations:
ITU-T K.20 “Resistibility of telecommunication equipment installed in a telecommunication centre to overvoltages and overcurrents” specifies resistibility requirements and test procedures for equipment installed in a telecommunication centre where the earthing, bonding and cabling between equipment/racks is in accordance with [ITU T K.27].
ITU-T K.21 “Resistibility of telecommunication equipment installed in customer premises to overvoltages and overcurrents” specifies resistibility requirements and test procedures for telecommunication equipment that is attached to or installed within a customer's premises.
ITU-T K.44 “Resistibility tests for telecommunication equipment exposed to overvoltages and overcurrents” – Basic Recommendation seeks to establish fundamental test methods and criteria for the resistibility of telecommunication equipment to overvoltages and overcurrents.
ITU-T K.45 "Resistibility of telecommunication equipment installed in the access and trunk networks to overvoltages and overcurrents" specifies resistibility requirements and test procedures for telecommunication equipment installed between telecommunication centres and between a telecommunication centre and the customer's premises.
ITU-T K.50 "Safe limits of operating voltages and currents for telecommunication systems powered over the network" provides guidance on voltages and currents that may safely be used to power telecommunication systems that are part of the telecommunications service providers’ network.
ITU-T K.51 "Safety criteria for telecommunication equipment" provides guidance on safety criteria for telecommunication network infrastructure equipment. It specifies requirements intended to reduce risks of fire, electric shock or injury for specified classes of person who may come into contact with the equipment.

TD1481 Rev.1
ITU-T K.64 "Safe working practices for outside equipment installed in particular environments" provides working procedures for maintenance activities in specific environments for telecommunication plants with voltage levels higher than the limits defined for analogue PSTN circuits. The specific environments covered in this Recommendation are characterized by wet conditions or close proximity to exposed metallic parts.
ITU-T K.75 "Classification of interface for application of standards on resistibility and safety of telecommunication equipment" provides guidance to manufacturers, network operators and test houses on the classification of the type of interface, i.e., external (subjected to a.c. surges or conducted lightning surges) or internal (subjected to short fall-time transients induced into building cabling) and provides information on the waveform of transients appearing at equipment interfaces for insulation coordination purposes.
ITU-T K.95 - Annex A: Additional Transformer parameters to model Ethernet transformer differential surge let-through. This Annex is intended to help the designer to model the circuit operation during a differential surge condition from a few simple measurements on the Ethernet magnetics. It is assumed that whoever takes these measurements is competent in basic measurement techniques. TD1529

11th ITU Symposium on ICT, Environment and Climate Change
The 11th ITU Symposium on ICT, Environment and Climate Change took place on 21 April 2016 and was attended by over 300 participants. The objective of the symposium was to raise awareness of the potential ICTs possess to address environmental challenges and to encourage stakeholders to integrate existing and emerging ICT-based solutions into their activities for an overall ‘smarter’ and more holistically ‘sustainable’ future for mankind.
This Symposium brought together over 300 leading specialists in the field, from top policy-makers to engineers, designers, planners, government officials, regulators, standards experts and others.
The EMF Guide & Mobile App on EMF translated into Malay was launched during the Symposium by Dato'Jailani Johari, Deputy Minister of Communication & Multimedia, Malaysia. The Deputy Minister highlighted the importance of effective and clear communication with the Malaysian public and how the EMF Guide will provide a most valuable resource.
The presentations on EMF included an update from the World Health Organization, a global approach to EMF Management and standards, and updates on measurements and calculations of EMF from ITU-T SG5 experts, and EMF Enforcement & Regulatory Approaches in Malaysia.

Connect 2020 Agenda
Two sessions on Connect 2020 agenda with a special focus on environmental sustainability goals took place on 20 and 25 April 2016.
An implementation initiative covering issuing pertaining to Greenhouse Gas (GHG) emissions and e-waste generated by the ICT sector was required to achieve the Connect 2020 Agenda targets for environmental sustainability. Within the Connect 2020 Agenda, Target 3.2 calls for the reduction of the volume of redundant e-waste by 50% by the year 2020, while target 3.3 advocates that GHG emissions generated by the telecommunication/ICT sector should be decreased per device by 30% by 2020. In order to facilitate the attainment of these targets, two separate roadmaps have been defined by ITU Study Group 5 on "Environment and Climate Change".
The Implementation Initiative includes several phases, including an initial definition of its vision and mission, according to the Connect 2020 goals and the ICT sector goals. Secondly, the initiative will be followed by an analysis of the requirements for the success of its implementation; including three steps: 1) the identification of the ICT Sector Challenges and Opportunities in this framework, 2) the definition of the correct execution model for the implementation initiative and 3) a financial model to allocate the necessary resources for the implementation initiative and the subsequent follow up.
The next part of the Initiative includes the roadmaps implementation activities to be carried out by the different actors, to guarantee the accomplishment of the Connect 2020 targets. Finally, the Initiative will require the definition of several metrics and Key Performance Indicators (KPIs) to follow up on the advancement of the roadmaps and their success. This must be supported by an effective communications plan, led by ITU and its members.
In addition, this Initiative proposes an implementation schedule from early 2016 until 2020, based on which decisive actions must be taken in the second semester of 2016. Activities in the individual roadmaps cover the attainment of targets pertaining to the reduction of GHG emissions and e-waste and aim to contribute to meet the UN Sustainable Development Goals (SDGs), adopted by UN-Member States in September, 2015 and the Paris Agreement adopted in December 2015.
