Overview

EN 13529:2003 is a European Standard developed by CEN that specifies the test methods for assessing the resistance of surface protection systems to severe chemical attack on concrete structures. This standard applies to products and systems designed for the protection and repair of concrete and provides a systematic approach to evaluate their durability when exposed to harsh chemical environments.

The standard outlines the principles, apparatus, sampling methods, test procedures, and evaluation criteria necessary for determining the chemical resistance of coatings and protective layers applied to concrete substrates. EN 13529:2003 supports manufacturers, testing laboratories, and construction professionals in ensuring the reliability and longevity of protective coatings used in chemically aggressive conditions.

Key Topics

Scope and Purpose

• Focuses on surface protection systems for concrete structures
• Evaluates resistance to severe chemical attack to predict durability
• Addresses protection and repair applications

Test Specimens and Preparation

• Use of concrete slabs prepared per EN 1766
• Surface preparation by grit-blasting for uniformity
• Coating application and curing follow manufacturer’s instructions
• Measurement of coating thickness according to EN ISO 2808

Testing Apparatus

• Metal frame with bell-type caisson chambers to contain testing liquids
• Application of pressure (1 bar) during testing or without pressure
• Testing chamber uses rubber cuff seals to maintain containment

Test Procedure

• Testing liquids chosen according to Annex A or agreed mutually
• Exposure durations typically include 1, 3, 7, 28, or 90 days depending on requirements
• Two separate exposure areas possible with use of dual rings
• Initial and post-exposure hardness measurements (EN ISO 868, EN ISO 2815)

Evaluation Criteria

• Visual inspection for blistering, flaking, cracking, and optical changes per ISO 4628 series
• Measurement of coating hardness and adhesion changes
• Assessment of liquid penetration through coating
• Post-test coating thickness measurement

Reporting Requirements

• Detailed test reports covering test conditions, materials, results, and any method deviations
• Clear identification of product batch, testing laboratory, and reference to EN 13529

Applications

EN 13529:2003 is essential for assessing the chemical resistance of protective coatings and repair systems used in concrete infrastructure exposed to aggressive chemicals. Typical applications include:

• Industrial Flooring and Structures: Protection of concrete floors and structural elements in chemical plants, refineries, and manufacturing facilities.
• Wastewater Treatment Plants: Coatings resistant to acids, alkalis, and organic solvents encountered in treatment environments.
• Marine and Coastal Structures: Durability testing against saltwater, hydrocarbons, and other corrosive substances.
• Transportation Infrastructure: Surface protection for bridges, tunnels, and highways exposed to de-icing salts and chemical pollutants.
• Storage and Containment Areas: Concrete protection in tanks or areas where chemical spills may occur.

This standard enables manufacturers to validate product performance, regulatory bodies to ensure compliance, and end-users to select appropriate surface protection systems for chemically demanding environments.

Related Standards

EN 13529:2003 complements several other important standards for concrete protection and repair, including:

• prEN 1504-2: Defines requirements, definitions, and conformity evaluation for surface protection systems of concrete structures.
• EN 1766: Provides guidelines for producing reference concrete specimens on which protection systems are tested.
• EN ISO 868 & EN ISO 2815: Test methods for determining hardness of coatings, used in evaluating chemical resistance.
• ISO 4628 series: Standards for assessing coating degradation including blistering, cracking, and flaking.
• prEN 1062-7: Related test methods for crack-bridging properties of coatings on concrete.

Understanding the interplay between EN 13529 and these standards is vital for comprehensive quality control, durability assessment, and certification of concrete protection products.

3 Principle
Resistance of the coating system to severe chemical attack is assessed by exposing one side of the surface
protection system to the testing liquid.
4 Apparatus
4.1 Laboratory maintained at the temperature of (21 – 2) °C and the relative humidity of (60 – 10) %.
4.2 Usual accessories to apply the surface protection system to the basic test pieces.
4.3 Concrete slabs as basic test pieces, according to EN 1766.
4.4 Test apparatus
The test apparatus consists of a metal frame to take up the test piece and to clamp one or two bell-type caisson
chambers (see Figure 1) The bell-type caisson chamber consists of a bell-type steel cup with an inner diameter
of > 100 mm. (The tested area is a circle with a diameter of 100 mm inside of the glued rings). It is connected to a
compressed air vessel equipped with a pressure reducing valve via a compressed air hose. The pressure device is
fixed on the surface protection system by a metal clamp. To ensure the tightness of the caisson chamber, a rubber
cuff is placed between the surface protection system and the caisson chamber.
