Nanomanufacturing - Reliability assessment - Part 3-1: Graphene-based material - Stability: Temperature and humidity test
IEC TS 62876-3-1:2022(E) establishes a standardized method to determine the
• stability
of films of graphene-based material by a
• temperature and humidity test.
It establishes a general methodology for reliability stress screening (RSS) to qualify the use of graphene-based material in its subsequent product value stage. The intention is to prepare test samples undergoing the same or similar failure mechanisms as the graphene-based material in the final product.

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.

INTRODUCTION
Graphene, a single-layer of carbon atoms arranged in a honeycomb lattice, has a high potential
for future nanotechnology applications due to the excellent conductivity, transparency and
flexibility of the material. Many research organizations and industrial companies are developing
fabrication technologies for graphene films on substrates, as dry powders or graphene in liquid
dispersions for a wide variety of applications. Therefore, the need for a system of standardized
tests for the key control characteristics to benchmark graphene material in its different physical
and chemical modifications remains critical. The absence of such a system slows down the
development process and hinders companies to be commercially successful. To improve this
situation, IEC TC 113 is developing a comprehensive system of material specifications
(IEC 62565-3-X series) which list application relevant key control characteristics (KCCs) and
the related measurement standards (IEC 62607-6-X series) for graphene materials in general.
That includes graphene, few-layer graphene and multilayer graphene, graphene oxide and other
graphene-related materials.
In addition to the KCCs to qualify graphene material after fabrication, it is also important to
obtain information on its long-term stability. This document defines the conditions for a set of
stress tests to qualify graphene material for an acceptable level of reliability and durability in
its performance category and operating service environment.
These tests are performed using samples with graphene material layers on the same subs
