IEC 62668-2:2019

Process management for avionics - Counterfeit prevention - Part 2: Managing electronic components from non-franchised sources

IEC 62668-2:2019, defines requirements for avoiding the use of counterfeit, recycled and fraudulent components when these components are not purchased from the original component manufacturer (OCM) or are purchased from outside of franchised distributor networks for use in the aerospace, defence and high performance (ADHP) industries. This practice is used, as derogation, only when there are no reasonable or practical alternatives.
NOTE: Typically this document is used in conjunction with IEC 62239-1 and IEC 62668-1, enabling ADHP industries to manage and avoid the use of counterfeit, recycled and fraudulent components in their supply chains.
Although developed for the ADHP industry, this document can be used by other high-performance and high-reliability industries, at their discretion.
This first edition cancels and replaces the second edition of IEC TS 62668-2 published in 2016. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the second edition of IEC TS 62668-2:
a) updates to the risk assessment process, including reference to SAE AS6081;
b) updates to the test methods, including reference to the SAE AS6171 test methods published and in development;
c) updates in line with IEC 62668-1 for definitions and references to DFARS.

FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 62668-2 has been prepared by IEC technical committee 107:

Process management for avionics.

This first edition cancels and replaces the second edition of IEC TS 62668-2 published in

INTRODUCTION

The avionics industry has a responsibility to ensure that all flight equipment produced has a

predicted product life which correlates with the predicted repair and service life to ensure the

public is not endangered. Typically, an original equipment manufacturer (OEM) calculates a

mean time between failure (MTBF) and possibly a mean time to failure (MTTF) prediction.

These calculations assume all components are new, or considered as “unused”, at the point

of introduction into flight use and that no useful component life and/or any “unsafe”

component conditions have been used. It is therefore essential that counterfeit, recycled and

fraudulent components which have had potentially some of their ”useful life” consumed and

which can also be malfunctioning are not purchased for use in aerospace, defence and high

performance (ADHP) industries.

PROCESS MANAGEMENT FOR AVIONICS –
COUNTERFEIT PREVENTION –
Part 2: Managing electronic components
from non-franchised sources
1 Scope

This part of IEC 62668, defines requirements for avoiding the use of counterfeit, recycled and

fraudulent components when these components are not purchased from the original

component manufacturer (OCM) or are purchased from outside of franchised distributor

networks for use in the aerospace, defence and high performance (ADHP) industries. This

practice is used, as derogation, only when there are no reasonable or practical alternatives.

NOTE Typically this document is used in conjunction with IEC 62239-1 and IEC 62668-1, enabling ADHP

industries to manage and avoid the use of counterfeit, recycled and fraudulent components in their supply chains.

Although developed for the ADHP industry, this document can be used by other high-

performance and high-reliability industries, at their discretion.

3.1.2
broker

individual or corporate organization that serves as an intermediary between buyer and seller

Note 1 to entry: In the electronic component sector a broker specifically seeks to supply obsolete or hard to find

components in order to turn a profit. To do so it may accumulate an inventory of components considered to be of

strategic value or may rely on inventories accumulated by another. The broker operates within a worldwide

component exchange network.
[SOURCE: IEC 62668-1:2019, 3.1.2]
3.1.3
COTS product
commercial off-the-shelf product

one or more components, assembled and developed for multiple commercial consumers,

whose design and/or configuration is controlled by the manufacturer’s specification or industry

standard

Note 1 to entry: COTS products can include electronic components, subassemblies, or assemblies, or top-level

assemblies. Electronic COTS subassemblies or assemblies include circuit card assemblies, power supplies, hard

drives, and memory modules. Top-level COTS assemblies include a fully integrated rack of equipment such as raid

arrays, file servers to individual switches, routers, personal computers, or similar equipment.

Note 2 to entry: This note applies to the French language only.

3.1.4
counterfeit, verb

action of simulating, reproducing or modifying a material, good or its packaging without

authorization

Note 1 to entry: It is the practice of producing products which are imitations or are fake goods or services. This

activity infringes the intellectual property rights of the original manufacturer and is an illegal act. Counterfeiting

generally relates to willful trademark infringement.
[SOURCE: IEC 62668-1:2019, 3.1.4]
3.1.5
counterfeited component

material good imitating or copying an authentic material, good which may be covered by the

protection of one or more registered or confidential intellectual property rights

Note 1 to entry: A counterfeited component is one whose identity or pedigree has been altered or misrepresented

by its supplier.

Identity = original manufacturer, part number, date code, lot number, testing, inspection, documentation or warranty

etc.

Pedigree = origin, ownership history, storage, handling, physical condition, previous use, etc.

Note 2 to entry: When a material good has no registered or confidential intellectual property rights, then the

material good has no intellectual property protection. Examples include situations where the original component

manufacturer (OCM) has ceased to trade and has not sold or passed on the intellectual property rights to another

entity.

franchised distributor or agent

individual or corporate organisation that is legally independent from the franchiser (in this

case the electronic component manufacturer or OCM) and agrees under contract to distribute

products using the franchiser’s name and sales network

Note 1 to entry: Distribution activities are carried out in accordance with standards set and controlled by the

franchiser. Shipments against orders placed can be dispatched either directly from the OCM or the franchised

distributor or agent. In other words, the franchised distributor enters into contractual agreements with one or more

electronic component manufacturers to distribute and sell the said components. Distribution agreements may be

stipulated according to the following criteria: geographical area, type of clientele (avionics for example), maximum

manufacturing lot size. Components sourced through this route are protected by the OCM’s warranty and supplied

with full traceability.
[SOURCE: IEC 62668-1:2019, 3.1.9]
3.1.10
fraudulent component

electronic component produced or distributed either in violation of regional or local law or

regulation, or with the intent to deceive the customer

Note 1 to entry: This includes but is not limited to the following which are examples of components which are

fraudulently sold as new ones to a customer:
1) a stolen component;

2) a component scrapped by the original component manufacturer (OCM) or by any user;

3) a recycled component, that becomes a fraudulent recycled component when it is a disassembled (for example,

disassembled from a PCB assembly) component resold as a new component (see Figure 1), where typically

there is evidence of prior use and rework (for example solder, re-plating or lead re-attachment activity) on the

component package terminations;

4) a counterfeit component, a copy, an imitation, a full or partial substitute of brands;

5) fraudulent designs, models, patents, software, or copyright sold as being new and authentic. For example: a

component whose production and distribution are not controlled by the original manufacturer;

6) unlicensed copies of a design;

7) a disguised component (remarking of the original manufacturer’s name, reference date/code or other

identifiers etc.), which may be a counterfeit component (see Figure 1);

8) a component without an internal silicon die or with a substituted silicon die which is not the original

manufacturer’s silicon die.

3.1.13
non-franchised distributor
companies which do not fall under a franchised distributor or OCM

Note 1 to entry: These distributors may purchase components from component manufacturers, franchised

distributors, or through other supply channels (open markets). These distributors cannot always provide the

guarantees and support provided by the franchised distributor network; components sourced through this source

are usually protected by the source’s warranty only.

Note 2 to entry: Some non-franchised distributors are able to purchase traceable components from the OCM or

their franchised distributors and prov
