What is IEC 62368-1?

Section 1 : Why / What / When

6

Less distinction today, in the recentpast and in the future among High-Tech products:

Similar technology,

Similar marketing/distributionchannels,

Similar use environments,

Similar users.

Why ?


Therefore, need a single safety standard that,

Applies to a broad range of HT products

But is technology independent, and allowsfor introduction of new technology easier

Allows for more design freedom

Minimizes need for national/regionaldifferences

Stable, understandable & user friendly

Based on Sound engineering, research &field data

Ultimately leads to design and manufactureof safe products !.

IEC 62368-1: Developed by IEC TC108 since 2002

New Safety Standard for– Consumer Electronic (Audio/Video) Apparatus,

– Information Technology Equipment, and

– Communication Technology Equipment

IEC 62368-1 : first published 21-01-2010

UL 62368-1 : first published 17-02-2012

Background

8

A Hazard-Based Safety Engineering Standard.( HBSE )

A performance-oriented Standard : ie - Technology Independent

A Product Specific Standard created upon• Sound Engineering

• Existing IEC Horizontal Standards ( 60950 & 60065 )

• Research

• Field Data

Covers Scopes of previous (legacy) Standards:

• IEC 60065 : Audio, Video & Similar Electronic Apparatus

• IEC 60950-1: Information & Communication Technology Equipment

• Will replace > 40% of all Existing CB schemes !! ))

What is it?What is IEC 62368-1?

9

Not a simple Merger of IEC 60065 & 60950-1 !– Although many common elements…

Not a Generic (ie Industry versus Residential) HBSE Standard !– Standard is only applicable to products falling under its scope.

– Standard has both requirements and compliance criteria, eitherperformance-based or prescribed constructions.

– Standard is fully compatible with a IECEE CB Scheme, and 3rd PartyMark Certification Programs !

What is it not?


Not a Risk-based Standard !– Risk Analysis not required (aka, IEC 60601-1, Third Edition) during

application & certification.

– Decision on application of requirements does not involve riskconsiderations...

Note : Some Risk Analysis was used by IEC TC108 at the technical committee level to develop the

actual requirements, eg. levels/limits associated with Class 1, 2 & 3…

Standard 62368-1 is based on the principles of Hazard Based Safety

Engineering (HBSE)

Hazard Based Safety Engineering

• Hazard Energy Sources can be Electrical(Shock & Fire)/Chemical/ Thermal(Heat)/Mechanical/Radiation

• Energy transfer is based on the amount of energy and the effectiveness of the transfer mechanism.

• Injury occurs when energy of sufficient magnitude and duration is imparted to a Body part

HazardousEnergySource

Hazardous Model

Hazardous : Hazard : An Energy Source that exceeds Body susceptibility Limits

Safety : Safe : Situation where at least one safeguard is interposed between thebody and a hazardous energy source

HBSE Flow Chart

Hazard Based Safety Engineering

16

IEC 62368 is a PRODUCT Safety Standard that :

• Defines Users = Body part ( ie persons = Ordinary/Instructed/Skilled )

• Identifies Energy Sources: (Electrical/Thermal(Heat)/Chemical/Mechanical etc)

• Classifies Energy Sources & defines its Class ( or limits )(Class 1= Detectable : Class 2 = Pain : Class 3 = Injury )

• Describes & Provides guidance for the Safeguards against those energysources. ( location / properties / parameters / construction etc )

• Advises Test that Qualifies the safeguards as been effective

Note : The prescribed safeguards are intended to reduce the likelihood of pain, injury and, in the case of fire,

property damage.

Objective

– Able to identify Class 2 or greater energy hazards and take appropriateprecautions

– May have access to restricted locations

– Should not be exposed to hazardous energy

Skilled Person:– Trained or posses experience

62368-1 : Hazardous Energy Sources - 6 types

19

Three classes of energy sources

– Defined by Magnitudes and Durations of source parameters relative to eitherthe BODY or to Combustible Material and responses to those energy sources.

– Each energy class is a function of the body part or the combustible materialsusceptibility to that energy magnitude.

Level of Hazardous Energy Source

EnergySource

Effect on the body Effect on combustible materials

Class 1 Not painful, but may be detectable Ignition not likely

Class 2 Painful, but not an injury Ignition possible, but limitedgrowth and spread of fire

Class 3 Injury Ignition likely, rapid growth andspread of fire

Response to Energy Sources

62368-1 : Hazardous Energy Class – 3 Types

Green = OK : Amber = Caution : Red = Dangerous

20

Under normal operating conditions and abnormal operating conditions, the energy incontact with a body part, may be detectable, but is not painful nor is it likely to cause aninjury. For fire, the energy is not likely to cause ignition.

Under single fault conditions, energy in contact with a body part, may cause pain, butnot likely causes injury.

Class 1 Energy Source

It is an energy source with levels exceeding class 1 limits and not exceeding class 2limits under normal operating conditions, abnormal operating conditions, or singlefault condition. The energy under contact with a body part, may be painful, but is notlikely to cause an injury. For fire, the energy can cause ignition under some conditions.



It is an energy source with levels exceeding class 2 limits under normal operatingconditions, abnormal operating conditions, or single fault condition, or any energysource declared to be a class 3 source. The energy under contact with a body part,is capable of causing injury. For fire, the energy may cause ignition and the spreadof flame where fuel is available.

62368-1 : Hazardous Energy Sources

21

A safeguard is a Device or Scheme or System that is:– Is interposed between an energy source and a body part or property,

and

– Reduce the likelihood of transfer of energy to a body part or property

What is a Safeguard

HazardousEnergySource

BodyParts

Safeguards

62368-1 : SAFEGUARDS

Products necessarily use energies capable of causing injury or pain or property damage( Hazardous Energies )

22

Safeguard mechanisms against transfer of energy capable of causing pain orinjury include

– attenuating the energy (reduces the value of the energy)

– impeding the energy (slows the rate of energy transfer)

– diverting the energy (changes the energy direction)

– disconnecting, interrupting, or disabling the energy source

– enveloping the energy source (reduces the likelihood of the energy from escaping)

– interposing a barrier between a body part and the energy source

Mechanisms of Safeguards

A SAFEGUARD :– can be applied to the equipment

– to the local installation

– to a person

– or can be a learned or directed behavior (for example, resulting from aninstructional safeguard) intended to reduce the likelihood of transfer of energycapable of causing pain or injury

– A safeguard may be a single element or may be a set of elements

Use of Safeguards


23

Ideally, the order of preference for providing Safeguards is:

– EQUIPMENT safeguards(ie NO Knowledge required by persons coming into contact with the equipment )

– INSTALLATION safeguards(ie a safety guard must be provided after installation ( eg Bolting to the Floor / Earth Connectionrequired )

– PERSONAL safeguards( ie invoking personal protective equipment )

– BEHAVIORAL safeguards [ Instructional / Precautionary / Skill ]

( ie invoking avoidance behavior when equipment requires access to an Energy Source )

Safeguard : Order of Priority / Hierarchy

In practice, safeguard selection will take account of the nature of the energysource, the intended user, the functional requirements of the equipment, andsimilar considerations. Blue are important for Component PSU’s...


24

BASIC Safeguard – safeguard that provides protection under normal

operating conditions and under abnormal operating conditions wheneveran a Hazardous Energy Source is present in the equipment

Example : Creepage & Clearance

SUPPLEMENTRY Safeguard – safeguard applied in addition to the basicsafeguard that is or becomes operational in the event of failure of thebasic safeguardExample : Earth Connection required

REINFORCED safeguard – single safeguard that is operational under:

• normal operating conditions,

• abnormal operating conditions, and

• single fault conditions

Example : Reinforced Insulation / Electrical Insulated Glove

Note : Double Safeguard - safeguard comprising both a basic safeguard and asupplementary safeguard & is considered equivalent to REINFORCED

Section 5 – Electrical Caused Injury : ( Shock )

Includes many well known elements of 60950, but presented in a different way, including:

• Classification of Energy Sources ( 5.2 ) : ES1/ES2/ES3 Limits

• Levels of Protection against hazardous energy sources ( 5.3 ): Safeguard # = 0:1:2

• Insulation Materials as safeguards, including clearances & creepage distances,solid insulation, and electric strength (5.4) - Less stringent that 60950

• Components as safeguards (5.5)( eg Capacitor Discharge / Transformer ‘s / Relays / Opto’s etc .. )

• Protective Conductors ( Earthing & Bonding) as safeguards (5.6)(eg Earth Wire size)

• Touch Voltage, Touch Current (leakage) and protective conductor current Limits (5.7)- Less stringent that 60950

Some Relevant changes from 2’nd Ed to 3’rd Ed of IEC62368‐1:

Requirements for Outdoor Equipment has been included. The outdoorrequirement used to be stated only on the older standard (IEC60950‐22)

Accepts the use of Fully Insulated Winding wire (FIW) for reinforced insulation.The older standard (IEC62368‐1 2nd) did not accept the insulation FIW for Basic orReinforced insulation.

Allows the IEC60950‐1 method for determination of top, bottom and side openingsfor Fire enclosures. This is less stringent compared to IEC62368‐1 2nd Ed.

New test condition for Discharge Resistor to waive the application of single fault.

Status of 62368 Standard : Transition Time Lines (Oct 2018)


41

62368 is Easier to achieve …– less strict limits compared to 60950

– Principles / Definitions / Requirements are more clearly explained

– more alternative ways to fulfill the standard requirements

62368 is Complicated …– stricter requirement on component selection, e.g. resistor, insulation

system, etc.

– classification of energy source & safeguards is new.

– Fire enclosure and PIS (Potential Ignition source) cone is a differentconcept from 60950..
