Overview

ISO 19095-2:2015 - Plastics - Evaluation of the adhesion interface performance in plastic‑metal assemblies - Part 2: Test specimens specifies the forms and preparation of test pieces used to evaluate adhesion at plastic–metal interfaces. It defines the appropriate specimen types and the information to report so that interface performance tests are consistent and traceable. ISO 19095-2 is one part of the ISO 19095 series (Parts 1–4) addressing methodology, test methods and environmental durability.

Key topics and requirements

• Scope: Specifies test specimens for evaluating adhesion interface performance in plastic‑metal assemblies where conventional methods may be inadequate.
• Specimen types: Defines standard geometries and dimensions (illustrated in the standard) for:
  • Type A - butt welded test specimens
  • Type B - overlapped test specimens
  • Type C - peeling test specimens (flexible metal + plastic, with a defined unbonded length)
  • Type D - specimens for sealing properties (with an Annex A alternative D.2 overlapped designs if D cannot be manufactured)
• Surface preparation: Requires surface preparation in accordance with ISO 17212 (guidelines for surface treatment of metals and plastics prior to adhesive bonding); any deviations must be recorded.
• Preparation methods: Cross‑references existing moulding standards for specimen manufacture, including ISO 293, ISO 294‑1/2, ISO 295, ISO 10724‑1/2 depending on material and moulding method.
• Reporting requirements: Test reports must include specimen type and size, preparation and testing conditions, surface treatment, number of tests and specimens, measured characteristic values (averages), dates, processing methods and other relevant details (items a–m in the standard).

Applications and users

ISO 19095-2 is applicable where reliable evaluation of plastic–metal adhesion is critical, such as:

• Automotive and aerospace component manufacturers using hybrid plastic‑metal structures
• Materials engineers and adhesion specialists developing bonded assemblies
• Test laboratories performing adhesion, peel and sealing tests
• R&D teams validating surface treatments, welding or bonding processes
• Quality assurance and regulatory compliance teams comparing interface performance across suppliers

Using standardized test specimens improves reproducibility, traceability and comparability of adhesion test results across labs and projects.

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).

Introduction
Structures of heterogeneous materials are being manufactured in the automobiles and aerospace
industry sectors where higher safety margins are required.
The existing test methods are not appropriate because the evaluation of the plastic-metal interface
performance 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 plastic-metal interface performance.
A test method to evaluate accurately 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 the integrity of th
