Coil coated metals - Test methods - Part 29: Resistance to environmental soiling (Dirt pick-up and striping)

This part of the EN 13523 series specifies a procedure for the comparative evaluation of resistance to soiling of an organic coating on a metallic substrate (coil coating) in an outdoor exposure environment, particularly the soiling defect known as "Tiger stripes".

Le présent document spécifie un mode opératoire à appliquer pour déterminer, par comparaison, la résistance à la pollution d’un revêtement organique appliqué sur un subjectile métallique (prélaquage en bandes continues) dans un environnement d’exposition à l’extérieur, en particulier la salissure appelé « zébrures ».
En plus des zébrures, d’autres types de rétention de salissure peuvent être observés.

Overview

EN 13523-29:2024 - Coil coated metals: Test methods - Part 29: Resistance to environmental soiling (Dirt pick-up and striping) is a CEN standard that defines a comparative outdoor exposure procedure to evaluate how organic coatings on metallic substrates resist environmental soiling, in particular the soiling defect known as “tiger stripes”. The standard replaces EN 13523-29:2017 and is intended for coil coated metals used in architectural and industrial applications.

Key topics and requirements

  • Test principle: Comparative outdoor exposure of test panels alongside two reference panels (one known good, one known poor) to concentrate atmospheric dirt and rainwater into rivulets that produce dirt pick-up and striping.
  • Exposure rack: Uses the EN 13523-19 exposure rack area modified with a UV-stable polymeric collector (e.g., polycarbonate) set at 10°–12°. The collector is machined with grooves 3 mm wide × 3 mm deep at 3 mm spacing to channel runoff.
  • Sample preparation: Panels must be flat, uncontaminated and sized 100 mm × (200–400 mm); coil samples should be cut with the longest dimension in the rolling direction.
  • Test duration: Typically 3 months, with a maximum of 6 months, run continuously to avoid confounding weathering effects; start date should be recorded to reduce seasonal bias.
  • Evaluation and ranking: Visual comparison and ranking relative to reference panels (better/same/in-between/worse); optional instrumental measurements of gloss (EN 13523-2) and colour (EN 13523-3) at specified measuring points (triplicate readings).
  • Cleaning (wash) test: Left half of panel may be washed with water containing 0.5% non‑reactive detergent (pH 6–7) using a non‑abrasive cloth; washed vs unwashed areas are re-evaluated.
  • Documentation: Photographic record and a test report including product identification, rack location, duration, results, deviations and anomalies.

Applications and users

EN 13523-29:2024 is used by:

  • Coil coater manufacturers and quality control labs to assess resistance to environmental soiling and susceptibility to tiger stripes.
  • Specifiers, architects and façade engineers when selecting coated metal products for outdoor exposure.
  • Product development teams comparing coating formulations, topcoats or pretreatments.
  • Independent test laboratories performing standardized comparative exposure tests.

This standard helps stakeholders validate product performance in service-like conditions, inform procurement specifications, and reduce field failures caused by dirt pick-up and striping.
