Description (English):

ISO 28722:2008 specifies the requirements for enamel-coated, plane, cold-rolled, heavy- and light-gauge steel panels intended for interior and exterior architectural use. It includes the functional and aesthetic characteristics and resistance to graffiti of these panels and the related coatings.

Abstract

Overview

ISO 28722:2008 - "Vitreous and porcelain enamels - Characteristics of enamel coatings applied to steel panels intended for architecture" defines requirements for enamel-coated, plane, cold-rolled heavy- and light-gauge steel panels for interior and exterior architectural use. The standard covers functional and aesthetic characteristics of vitreous/porcelain enamel coatings and specifies resistance to graffiti, providing test-based limits and acceptance criteria for enamelled architectural panels.

Key topics and technical requirements

Scope: Applies to enamel-coated steel panels intended for architectural cladding, facades and interior elements.
Substrate and coating layers: Steel shall conform to EN 10209; a minimum of two enamel layers on external faces and one on internal faces is required.
Final enamel thickness (measured per ISO 2178):
- Heavy-gauge external: 180–500 µm; internal: 100 µm
- Light-gauge external: 75–275 µm; internal: 60 µm
Adherence: Minimum Class 3 adherence (EN 10209 Annex D) after final firing.
Porosity: Open-pore limits defined by test (EN 14430 or ISO 8289 methods): e.g., max 10 pores/m2 (EN 14430).
Abrasion resistance: Taber test (ASTM C501) - maximum mass loss 0.1 g after 1,000 revolutions (S33, 1 kg).
Impact resistance: ISO 4532 pistol test - no damage greater than 2 mm diameter when activated at 20 N after 24 h.
Surface hardness & scratch: Mohs hardness ≥ 5 (EN 101); scratch resistance ≥ 7 N (ISO 15695). Metallic and silk-screened finishes: ≥ 4 N.
Flatness: Maximum deflection limits for finished panels (heavy gauge convex 0.5%, concave
