Overview
EN 14187-8:2017 is a European Standard developed by CEN that specifies a test method for evaluating the resistance of cold applied joint sealants to artificial weathering caused by UV-irradiation. This standard is essential for assessing how UV light affects the physical properties of cold applied joint sealants used in road construction and civil engineering works. The method involves exposing cured sealant specimens to controlled artificial UV light, humidity, and temperature conditions, then measuring changes in their mechanical behavior.
This test ensures that joint sealants can withstand environmental UV exposure, maintaining durability and functionality in outdoor applications.
Key Topics
Scope and Application
EN 14187-8:2017 describes a laboratory procedure to simulate artificial weathering using UV-irradiation and evaluates sealant degradation by measuring changes in tensile stress properties after exposure.Test Specimen Preparation
Test specimens consist of cured cold applied joint sealants mounted between concrete supports and spacers, prepared according to manufacturer instructions and conditioned prior to testing.Apparatus Requirements
- Artificial light source simulating daylight UV spectrum, conforming to EN ISO 4892-1 and EN ISO 4892-2.
- Black standard thermometer to measure surface temperature.
- Climate chamber maintaining test temperature at (40 ± 10) °C with humidity control via water spray or immersion.
- Tensile testing machine for elongation and stress-strain analysis.
Exposure Conditions
Specimens are elongated to 125% original width and exposed to UV light with a radiation intensity of (550 ± 75) W/m² for up to 1,000 hours. Wetting cycles ensure humidity effects, simulating natural weathering.Evaluation and Reporting
Changes in tensile stress at 100% or 140% elongation are calculated to quantify material degradation. Test reports must document test conditions, sealant details, irradiation time, climatic factors, observed changes, and any deviations from protocol.
Applications
Road Construction and Maintenance
Ensures that joint sealants used in pavement joints withstand UV-induced aging, extending road surface integrity and safety.Infrastructure and Civil Engineering
Validates durability of sealants applied to expansion joints, bridges, and other engineered structures exposed to sunlight.Sealant Product Development
Assists manufacturers in improving formulations with enhanced UV resistance to meet regulatory and performance requirements.Quality Control and Compliance
Provides a standardized method for certification bodies and laboratories to verify compliance with durability standards for cold applied joint sealants.
