IEC TS 62686-2:2019

Process management for avionics - Electronic components for aerospace, defence and high performance (ADHP) applications - Part 2: General requirements for passive components

IEC TS 62686-2:2019 defines the minimum requirements for general purpose "off-the-shelf" COTS (commercial off-the-shelf) passive components for aerospace, defence and high performance (ADHP) applications. This document applies to all passive components that can be operated in ADHP applications within the manufacturers’ publicly available data sheet limits in conjunction with IEC TS 62239-1. This document can be used by other high performance and high reliability industries, at their discretion.
ADHP application requirements are not necessarily fulfilled by this document alone. ADHP original equipment manufacturers (OEMs) could consider redesigning their products or conducting further testing to verify suitability in ADHP applications using their procedures for satisfying their electronic component management plan (ECMP) (see IEC TS 62239-1).
This first edition cancels and replaces IEC PAS 62686-2 published in 2016.

HIGH PERFORMANCE (ADHP) APPLICATIONS –
Part 2: General requirements for passive components
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.

The main task of IEC technical committees is to prepare International Standards. In

exceptional circumstances, a technical committee may propose the publication of a technical

specification when

• the required support cannot be obtained for the publication of an International Standard,

despite repeated efforts, or

• the subject is still under technical development or where, for any other reason, there is the

future but no immediate possibility of an agreement on an International Standard.

Technical specifications are subject to review within three years of publication to decide

whether they can be transformed into International Standards.

IEC TS 62686-2 which is a technical specification, has been prepared by IEC technical

committee 107: Process management for avionics.
---------------------- Page: 7 ----------------------
– 6 – IEC TS 62686-2:2019 © IEC 2019

This first edition cancels and replaces the first edition of IEC PAS 62686-2 published in 2016.

This edition constitutes a technical revision.
The text of this technical specification is based on the following documents:
Enquiry draft Report on voting
107/302/DTS 107/343/RVDTS

Full information on the voting for the approval of this technical specification can be found in

the report on voting indicated in the above table.

This document has been drafted in accordance with the ISO/IEC Directives, Part 2.

A list of all the parts in the IEC 62686 series, published under the general title Process

management for avionics – Electronic components for aerospace, defence and high
performance (ADHP) applications, can be found on the IEC website.

The committee has decided that the contents of this document will remain unchanged until the

stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to

the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
A bilingual version of this publication may be issued at a later date.

INTRODUCTION

This part IEC 62686 includes all the requirements of the obsolete STACK Specification

S/0003 issue 2 related to passive components and contains revisions for alternative

qualification test methods and additional test information for the aerosapace, defence and

high performance (ADHP) industries. This document is typically used in conjunction with

IEC TS 62239-1.

NOTE With the addition of alternative methods, it is possible for manufacturers to be audited by IECQ under the

new IECQ automotive scheme or IECQ approved component scheme.

PROCESS MANAGEMENT FOR AVIONICS – ELECTRONIC
COMPONENTS FOR AEROSPACE, DEFENCE AND
HIGH PERFORMANCE (ADHP) APPLICATIONS –
Part 2: General requirements for passive components
1 Scope

This part of IEC 62686 defines the minimum requirements for general purpose "off-the-shelf"

COTS (commercial off-the-shelf) passive components for aerospace, defence and high

performance (ADHP) applications.

This document applies to all passive components that can be operated in ADHP applications

within the manufacturers’ publicly available data sheet limits in conjunction with

IEC TS 62239-1. This document can be used by other high performance and high reliability

industries, at their discretion.

ADHP application requirements are not necessarily fulfilled by this document alone. ADHP

original equipment manufacturers (OEMs) could consider redesigning their products or

conducting further testing to verify suitability in ADHP applications using their procedures for

satisfying their electronic component management plan (ECMP) (see IEC TS 62239-1).
