Overview

EN ISO 22553-15:2023 (ISO 22553-15:2022) specifies a laboratory test method to estimate the influence of permeate residues - jetting liquids from the rinsing process after electro-deposition coating (e-coat) - on the appearance and integrity of electro-deposition coatings. The standard targets automotive and other general industrial applications (e.g., chiller units, consumer products, radiators, aerospace, agriculture) where residual rinse fluids can cause colour changes or surface defects during curing.

Key topics and technical requirements

• Test principle: Coat pretreated, electrically conductive test panels with the electro-deposition material, introduce test substances (permeate residues) into indentations on the wet coat, then stove (cure) and assess visually. A corrosion test may follow if required.
• Test panels: Typical panel size ~190 mm × 105 mm × 0.75 mm with six indentations; indentation depth ~2.5 mm recommended. Each test substance is applied in duplicate.
• Test substance application: Use a pipette to deposit ~0.1 ml of each test fluid into indentations.
• Laboratory deposition system: Deposition tank with circulation and DC voltage equipment; stirring (paddle or magnet) to maintain bath homogeneity and circulation during coating.
• Coating and stoving controls: Maintain bath temperature to ±0.5 °C for deposition; oven tolerance ±2 °C up to 150 °C (±3.5 °C for 150–200 °C) as specified.
• Evaluation: Visual assessment according to referenced visual assessment standards; record changes in colour, surface appearance and any subsequent corrosion behaviour.
• Reproducibility: The procedure requires duplicate determinations and a blank panel for comparison.

Practical applications

• Validate and compare effects of rinse/permeate fluids from membrane or filtration systems on e-coat finishes.
• Support incoming quality control for rinse water, ultrafiltrate or additive residues in coating lines.
• Aid coating formulators and process engineers in troubleshooting post-deposition defects related to rinsing practices.
• Use in supplier qualification, process audits and failure analysis where rinse residues are suspected.

Who should use this standard

• Coating formulators and R&D laboratories
• Automotive and industrial coating process engineers
• Quality control and failure analysis teams
• Test labs and certification bodies evaluating electro-deposition coatings

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.
