Measurement procedures for materials used in photovoltaic modules - Part 1-5: Encapsulants - Measurement of change in linear dimensions of sheet encapsulation material resulting from applied thermal conditions

IEC 62788-1-5:2016 provides a method for measuring the maximum representative change in linear dimensions of encapsulation sheet material in an unrestricted thermal exposure as might or might not be seen during photovoltaic (PV) module fabrication. Data obtained using this method may be used by encapsulation material manufacturers for the purpose of quality control of their encapsulation material as well as for reporting in product datasheets. Data obtained using this method may be used by PV module manufacturers for the purpose of material acceptance, process development, design analysis, or failure analysis.

Procédures de mesure des matériaux utilisés dans les modules photovoltaïques - Partie 1-5: Encapsulants – Mesurage de la variation des dimensions linéaires des matériaux d'encapsulation en couches minces résultant des conditions thermiques appliquées

L'IEC 62788-1-5:2016 fournit une méthode de mesure de la variation maximale représentative des dimensions linéaires des matériaux d'encapsulation en couches minces dans le cas d'une exposition thermique non limitée qui pourrait se produire au cours de la fabrication de modules photovoltaïques (PV). Les données obtenues avec cette méthode peuvent être utilisées par les fabricants de matériaux d'encapsulation dans le but d'assurer le contrôle de la qualité de leurs matériaux, et de les consigner dans les fiches techniques de leurs produits. Les données obtenues avec cette méthode peuvent être utilisées par les fabricants de modules photovoltaïques à des fins d'acceptation des matériaux, d'élaboration de procédés, d'analyse de conception ou d'analyse de défaillances.

Merilni postopki za materiale, uporabljene v fotonapetostnih modulih - 1-5. del: Enkapsulanti - Merjenje sprememb linearnih dimenzij plošč materiala za enkapsulacijo zaradi toplotnih pogojev

Ta del standarda IEC 62788 zagotavlja metodo za merjenje največje reprezentativne spremembe linearnih dimenzij plošč materiala za enkapsulacijo pri neomejeni izpostavljenosti toploti, ki se jo morda lahko opazi med proizvodnjo fotonapetostnih (PV) modulov. Standard ne upošteva posledičnih obremenitev, do katerih lahko pride zaradi omejenih sprememb dimenzij ali trenja med proizvodnjo modulov.
Podatke, pridobljene s to metodo, lahko proizvajalci materiala za enkapsulacijo uporabijo za nadzor kakovosti svojih materialov za enkapsulacijo in navedbe v tehničnih listih izdelkov. Podatke, pridobljene s to metodo, lahko proizvajalci fotonapetostnih modulov uporabijo za namene sprejemljivosti materiala, razvoj procesov, analizo zasnove ali analizo napak.
Ta metoda se lahko uporablja tudi za preverjanje drugih materialov, npr. nosilnih plasti in prednjih plasti, kot je opisano v standardu IEC 62788-2. Določene podrobnosti preskusa (vključno z velikostjo preskušanca in podlage) so za ta način uporabe določene v standardu 62788-2.

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 62788-1-5 has been prepared by IEC technical committee 82:

Solar photovoltaic energy systems.
The text of this standard is based on the following documents:

MEASUREMENT PROCEDURES FOR MATERIALS
USED IN PHOTOVOLTAIC MODULES –
Part 1-5: Encapsulants –
Measurement of change in linear dimensions of sheet
encapsulation material resulting from applied thermal conditions
1 Scope

This part of IEC 62788 provides a method for measuring the maximum representative change

in linear dimensions of encapsulation sheet material in an unrestricted thermal exposure as

might or might not be seen during photovoltaic (PV) module fabrication. The standard does

not take into account any resulting stresses which may develop due to restricted dimensional

changes or friction during module fabrication.

Data obtained using this method may be used by encapsulation material manufacturers for

the purpose of quality control of their encapsulation material as well as for reporting in

product datasheets. Data obtained using this method may be used by PV module

manufacturers for the purpose of material acceptance, process development, design analysis,

or failure analysis.
This method may also be used to examine other materials, such as backsheets and

frontsheets as described in IEC 62788-2. Certain details of the test (including specimen size

and substrate) are specified for that application in 62788-2.
