Overview
EN ISO 22553-11:2021 (ISO 22553-11:2020) specifies a laboratory method for assessing bath stability of electro-deposition coatings used in the automotive sector and other industrial applications (e.g. chiller units, consumer products, radiators, aerospace, agriculture). The standard defines sample preparation, ageing conditions, the properties to monitor and minimum reporting requirements for a reproducible evaluation of an electrocoat bath over time.
Key topics and technical requirements
- Scope and purpose: Method to determine how electro-deposition coating baths change during storage/operation (bath stability).
- Sample preparation:
- Prepare at least 6 L of coating material (binder, pigment paste, demineralized water).
- Homogenize at (28 ± 3) °C (e.g. paddle stirrer ≥50 mm, 500 min⁻¹).
- Apparatus: Typical lab equipment plus a 5 L container, stirrer, thermostat system and a timer with 1 s accuracy.
- Ageing procedure:
- Use 5 L of the prepared material.
- Age uncovered with stirring at (30 ± 2) °C for approximately 90 days.
- Monitor volume loss (top up with demineralized water as required) and record amounts added; restore to 5 L after 90 days.
- Measurements (blank and after ~30, 60, 90 days):
- pH (ISO 19396-1)
- Electrical conductivity (ISO 15091)
- Solvent fraction (ISO 22518)
- Non-volatile-matter content (ISO 3251)
- Pigment content (ISO 14680-1 or ISO 14680-2)
- Sieve residue (ISO 22553-5)
- Volume charge density (ISO 22553-8)
- Evaluation & reporting:
- Report blank and aged results, tank temperature, water additions by time, deviations from method, anomalies, test date and material identification.
- Precision: No precision data provided in this part.
Applications and users
- Relevant to manufacturers and formulators of electro-deposition coatings (electrocoats/e-coats), quality laboratories, R&D teams, process engineers and suppliers to the automotive and wider industrial coatings market.
- Used to:
- Validate bath shelf-life and operational stability.
- Compare formulations or production batches.
- Support quality control, supplier qualification and trouble‑shooting of bath drift or performance loss.
