Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

ISO 19095-6:2021(E)
Introduction

Structures of heterogeneous materials are being manufactured in the automotive and aerospace

industry sectors, where higher safety margins are required. The existing test methods are not

appropriate because the evaluation of the adhesive interface is difficult, as the polymer material has a

relatively low mechanical strength and therefore fractures outside the joints. Therefore, it is necessary

to develop a methodology for the evaluation of the adhesive interfaces. A test method to accurately

evaluate the adhesion interface performance or standardization of long-term evaluation under harsh

environments is also necessary. The method in ISO 19095 is intended to ensure that the integrity of the

joint is realized through the interface and that traceability of the value improves the data comparison.

This document defines the conditions to evaluate the long-term durability which cannot be evaluated

using ISO 19095-4.

SAFETY STATEMENT — Persons using this document should be familiar with normal laboratory

practice, if applicable. This document does not purport to address all of the safety problems, if

any, associated with its use. It is the responsibility of the user to establish appropriate safety

and health practices. It is recognized that some of the materials permitted in this document

might have a negative environmental impact. As technological advances lead to more acceptable

alternatives for such materials, they will be eliminated to the greatest extent possible. At the

end of the test, care should be taken to dispose of all waste in an appropriate manner.

1 Scope

adhesion interface performance in plastic-metal assemblies.

3 Terms and definitions

4 Principle

To evaluate the degradation of plastic-metal assemblies under severe conditions in a shorter period of

time, the assemblies are subjected to a higher temperature and a higher humidity conditions such as

120 °C and 0,2 MPa of saturated water vapour pressure without air (oxygen) gas (see Annex B).

This method should be used at temperature at least 20 °C lower than softening temperature in order to

avoid deformation (see Annex C).
5 Apparatus

5.1 Oven, capable of heating to 200 °C for test samples or sealed pressure vessels connected to

pressure gauge and purge lines settled outside oven, with temperature control system (±1 °C).

To control the temperature uniformly inside the oven, an air circulation heating system should be used.

If conditions of 120 °C and 0,2 MPa of saturated water vapor pressure is used, a sterilizer (see 5.5) can

be used instead of oven and sealed pressure vessels.
