Structural adhesives - Corrosion - Part 1: Determination and classification of corrosion to a copper substrate
This European Standard describes a method to determine the ability of a liquid adhesive to corrode a copper substrate under heat ageing conditions. Temperatures and ageing periods are chosen to ensure the maximum differentiation between the corrosivity of different adhesives and are not intended to represent any particular service condition.
Strukturklebstoffe - Korrosion - Teil 1: Bestimmung und Klassifikation der Korrosion eines Kupfermaterials
Diese Europäische Norm legt ein Verfahren zur Bestimmung der Fähigkeit eines flüssigen Klebstoffes fest, um ein Kupfermaterial unter den Bedingungen einer Wärmealterung zu korrodieren. Die Temperaturen und die Zeitspannen der Alterung sind deshalb so gewählt, um eine maximale Unterscheidung zwischen der Korrosivität unterschiedlicher Klebstoffe sicherzustellen, und sollen nicht dazu dienen, unterschiedliche Anwendungsbedingungen nachzustellen.
Adhésifs structuraux - Corrosion - Partie 1: Détermination et classification de la corrosion d’un substrat en cuivre
La présente Norme européenne décrit une méthode permettant de déterminer l’aptitude d’un adhésif liquide à
corroder un substrat en cuivre dans des conditions de vieillissement à la chaleur. Les températures et les
périodes de vieillissement sont choisies de façon à différencier de manière optimale la corrosivité de plusieurs
adhésifs, elles ne sont pas destinées à représenter des conditions particulières d’utilisation.
Konstrukcijska lepila - Korozija - 1. del: Ugotavljanje in razvrstitev korozije na bakreni preskusni podlagi
Ta evropski standard opisuje metodo ugotavljanja zmožnosti tekočega lepila za korozijo na bakreni preskusni podlagi pod pogoji staranja zaradi vročine. Temperature in čas staranja so izbrani tako, da zagotavljajo maksimalno diferenciacijo med korozivnostjo različnih lepil in niso namenjeni predstavljanju katerega koli posebnega pogoja delovanja.

Overview
EN 1965-1:2011 - Structural adhesives - Corrosion - Part 1: Determination and classification of corrosion to a copper substrate - is a CEN standard that defines a laboratory method to assess the ability of a liquid structural adhesive to corrode a copper substrate under controlled heat‑ageing. The method uses standardized copper test plates, defined preparation and handling steps, and fixed ageing conditions (24 h at 50 °C or 100 °C) to maximise differentiation between adhesive corrosivity. These conditions are intended for comparative testing and are not representative of real service environments.
Key topics and technical requirements
- Scope: Measures chemical corrosion/tarnish caused by liquid adhesives on copper; electrochemical effects are minimised (no electrolyte, cleaned substrate).
- Materials: Uses electrolytically produced copper plates (ISO 6958 E‑Cu F30 recommended, typical cross‑section 12 mm × 2 mm), sulfur‑free hydrocarbon solvents that do not discolour copper, FEPA‑defined abrasives.
- Sample preparation: Abrade and polish all six faces of each copper plate using solvent‑wetted abrasive, store plates in solvent prior to testing, handle only with stainless tweezers to avoid contamination.
- Test procedure: Minimum of three plates per evaluation; coat plate with adhesive, heat‑age 24 h at 50 °C or 100 °C, rinse off uncured adhesive in solvent and dry before inspection.
- Classification: Visual grading 0–4 based on discolouration/tarnish/corrosion:
- 0 - No tarnish/corrosion
- 1 - Light tarnish (weak/pale orange)
- 2 - Moderate tarnish (wine‑red, lavender‑blue, silver/golden tones)
- 3 - Heavy tarnish (magenta, brass/red/green shimmer)
- 4 - Corrosion (transparent black/dark grey/brown, graphite black)
- Reporting: Test report must reference EN 1965-1, list product identification, copper plate details and preparation, corrosion grade, and any deviations or events affecting results.
Applications and users
EN 1965-1:2011 is used for:
- Product development and R&D to compare corrosivity of adhesive formulations.
- Quality control and incoming inspection by adhesive manufacturers and testing laboratories.
- Specification and selection of adhesives when copper substrates (or copper‑containing assemblies) are present.
- Procurement, certification bodies and technical specifiers who require documented corrosion classification for adhesives.
