Radio Spectrum and Technical Standards Advisory Committee
SSAC Paper 7/2018 for information
A Brief Overview of IEC 62368-1Audio/video, information and communication technology
equipment – Part 1: Safety requirements
Office of the Communications Authority29 August 2018
International Electrotechnical Commission (IEC)
2
Founded in 1906
world’s leading organization that prepares and publishesInternational Standards for all electrical, electronic andrelated technologies
over 20 000 experts from industry, commerce, government,test and research labs, academia and consumer groupsparticipate in IEC standardization work
All IEC standards are reviewed once every 5 years
Why IEC 62368-1 is needed
3
Existing safety standards could not keep up with technologyconvergence
IEC 62368-1 : safety standards for IT equipment, office appliances, consumer electronics, telecommunications equipment as well as combination of each
IEC 62368-1 caters for safety of IoT devices
Global Equivalence
4
Other Countries EquivalentStandard
Canada CSA 62368-1
South Korea KN 62368-1
Australia /New Zealand
AS/NZS 62368-1
Japan J62368-1
Scope of IEC 62368-1 (Partial List)
Consumer electronics amplifiers, game stations, musical instrument, etc.
Data processing and computer network equipment
PCs, laptops, LCD display, servers, routers, Ethernet switches, etc.
Office appliances
Shredders, cutting machines, copying machines, electronic type-writers, etc.
Telecommunications equipment
Network infrastructure, telephone systems, answering machines, modem, fixed and mobile phones, etc.

IEC 62368-1 At a Glance (1)
6
This international standard is a product safetystandard that classifies energy sources, prescribessafeguards against those energy sources, and providesguidance on the application of, and requirements for,those safeguards. The prescribed safeguards areintended to reduce the likelihood of pain, injury and, inthe case of fire, property damage.
Identify energy sources
Classify those energy sources

Audio, video and electronic apparatus
IT equipment
Covers audio/video and ICT equipment
New safety approach thatcovers the scope of the two legacy standards
Adopted in HKCA 2001 for regulating the lithium-ion battery safety of subscriber terminal equipment, andtransmission of excessive electrical voltage from fixed line subscriber terminal equipment

Safeguards (1)
Different safeguard for each kind of persons
Ordinary personUsers of the equipment, persons who may have access to the equipment or who may be in the vicinity of the equipment
Instructed personPerson instructed and trained or supervised by a skilled person
Skilled person
Person who has training and/or experience in the equipment technology. Expected to identify energy sourcesthat may cause pain or injury and take precautions to avoidcontact
11
Safeguard (2)
Classify the energy sources for the equipment
Electrical EnergySource
Effect on Body Effect on Combustible materials
Class 1 (ES1)Not painful, but may bedetectable
Ignition not likely
Class 2 (ES2) Painful, but no injuryIgnition possible, but limited growth andspread of fire
Class 3 (ES3) InjuryIgnition likely, rapid growth and spread offire
Safeguard Electrical energy sources capable of causing pain or injury to a body part; or electricity-caused fire

The manufacturer shoulddeclare energy class (ES1, ES2,ES3) and user class
Safeguards shall be applied according to the declared class
Transition from IEC 60950-1to IEC 62368-1
16
New Safety Approach of IEC 62368-1
17
IEC 62368-1Hazard-Based Approach
Identify hazards duringproduct development
Focus on preventinghazards, rather than following solutions
More performance options for manufacturersto demonstrate compliance
Technology independent
IEC 60950-1 Prescriptive Approach
Follow a set of design rules
Adhere to known solutions for hazardavoidance
Technology dependent

Changes related to telecom equipment
20
Telecommunications network and cable distributionsystem – replaced by external circuit, an electrical circuit(wired and wireless) external to the equipment and not themains
Telecommunication network voltages (TNVs) – replaced bydifferent class of electrical energy sources (ES1, ES2, ES3)
Requirement on battery safety includes coin /button cell batteries, i.e. covers safety of IoT and wearable devices

Date of Withdrawal of IEC 60950-1
20 Dec 2020
Global withdrawal of IEC 60950-1, IEC 62368-1 3rd
edition in force
20 June 2019
Original withdrawal date
of IEC 60950-1
Q3 2018Publication of IEC
62368-1 3rd edition
Feb 2014Publication of IEC
62368-1 2nd edition, gaining worldwide
acceptance
Jan 2010Publication of IEC
62368-1 first edition, not adopted worldwide
8 April 2016EU announced withdrawal date of EN 60950-1 as 20
June 2019
15 June 2018EU re-adjusted the
withdrawal date of EN 60950-1 as 20 Dec 2020
Why needs 6 years transition?
22
Expect a long lead time to learn and adapt to the new safety approach
Transitional provisions in 2nd Edition
23
Ease transition and implementation
Way Forward

OFCA Action Plan
Time Work planned/done
Oct 2017 Alerted certification bodies (CBs) of IEC 60950-1 to be superseded by IEC 62368-1 on 20.06.2019
Permitted CBs to assess compliance to HKCA 2001 by IEC 60950-1 or IEC 62368-1
July 2018 Alerted CBs global date of withdrawal of IEC 60950-1 as 20.12.2020Advised CBs to continue the dual-standard approach till 20.12.2020Informed CBs HK 2001 revision in end Q4 2020
Aug 2018 Brief the Spectrum and Technical Standards Advisory Committee on IEC 62368-1 development and the transition
Dec 2020 Revise HKCA 2001 and other HKCA 20xx specifications that adopt IEC 60950-1Amend certification scheme documents that mandate competence in safety
evaluation
Implications to Testing Agencies and CBs
Avoid last-minute rush, call for actions by testing laboratories and CBs now
Acquire training and knowledge of evaluating compliance to IEC 62368-1
Obtain accreditation to demonstrate technical competence in IEC 62368-1 safety testing and certification
