Overview

EN ISO 22553-13:2021 (Corrected version 2021-11) specifies a laboratory method to determine the re-solving behaviour of electro-deposition coatings (e-coats). Adopted by CEN, this part of the ISO 22553 series applies to cathodic and anodic electro-deposition coatings used in the automotive sector and other industrial applications (chiller units, consumer products, radiators, aerospace, agriculture). The method evaluates whether freshly deposited film dissolves again in the bath or during rinsing (including ultrafiltrate exposure).

Key topics and requirements

• Scope and terms: Defines re-solving, ultrafiltration (UF) and ultrafiltrate; references ISO 4618 and ISO 22553-1 terminology.
• Principle: Coat electrically conductive test panels in a laboratory deposition system, expose parts of the coated surface to the original e-coat bath and to the ultrafiltrate, then cure and assess film thickness and surface defects.
• Apparatus: Laboratory deposition tank with circulation and DC supply, film thickness gauge (max permissible error 0.1 µm), oven (stoving temperature control ±2 °C up to 150 °C), thermometer and timer.
• Test panels: Conductive panels with pre-treatment per ISO 1514; dimensions ~190 × 105 × 0.75 mm.
• Procedure highlights:
  • Homogenize bath (visible circulation) and set bath temperature (product-specific; typically 25–35 °C).
  • Deposit to nominal dry film thickness using appropriate voltage/time.
  • Sequential immersion: expose 2/3 then 1/3 of a panel to the e-coat bath (no voltage) for 10 min each, rinse; repeat on another panel using ultrafiltrate.
  • Cure/stove panels at the specified object temperature (typically 100–180 °C).
  • Measure dry film thickness at three points per area and calculate mean.
• Evaluation: Visual inspection for surface defects and rating of intensity (0–5) following ISO 4628-1:2016; report mean thicknesses and descriptive findings.
• Other: Single determination is standard; no precision data provided in the document.

Applications and users

This standard is intended for:

• Coating formulators and R&D labs assessing re-solving risk during bath circulation and rinsing.
• Quality control teams in automotive OEMs and Tier suppliers verifying e-coat robustness.
• Industrial coaters and testing laboratories for acceptance testing of cathodic/anodic e-coat systems.
• Suppliers of ultrafiltration systems and process engineers optimizing rinsing and bath maintenance.

Practical benefits include early detection of formulation or process issues that could lead to film defects, improved bath management, and clearer acceptance criteria for suppliers and manufacturers.

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).
