Overview

prEN 14187-5 (CEN) defines a standardized test method for determining the resistance to hydrolysis of cold applied joint sealants. The procedure evaluates how exposure to elevated temperature and high humidity affects the mechanical properties of sealants used in road and civil engineering joints. This draft European Standard is part of the EN 14187 series for cold applied joint sealants and references EN ISO 6927 (vocabulary) and EN ISO 868 (Shore hardness).

Key topics and requirements

  • Scope: Tests resistance to hydrolysis after an autoclave treatment at elevated temperature/high humidity.
  • Specimen preparation:
    • Round polyethylene moulds, diameter 50–70 mm, depth 10 mm.
    • Sealant conditioned 24 h at (23 ± 2) °C before moulding.
    • Three specimens per test; avoid air bubbles and trim flush with mould edge.
  • Conditioning before test: 28 days at (23 ± 2) °C and (50 ± 5) % RH to allow complete cure.
  • Test exposure:
    • Autoclave with 20–50 mm water layer on bottom; specimens placed above water on a support.
    • Test temperatures: (60 ± 2) °C, (70 ± 2) °C, (80 ± 2) °C.
    • Duration: 14 days in the autoclave inside a convection oven (60–100 °C capability).
    • Water level monitored during exposure.
  • Measurements:
    • Shore A hardness (EN ISO 868) measured before and after hydrolysis treatment.
    • After autoclave, specimens conditioned 24 h at (70 ± 2) °C prior to final hardness testing.
  • Result expression:
    • Resistance to hydrolysis reported as the percentage change in Shore A hardness using arithmetic mean values before and after testing.
  • Test report must include: reference to standard, sealant name/type/batch, conditioning details, resistance to hydrolysis value, specimen changes, deviations, and test date.

Applications and users

  • Useful for sealant manufacturers for product development and quality control.
  • Employed by independent testing laboratories for conformity assessment and certification.
  • Specifiers, contractors and asset owners in road construction and civil engineering use results to compare products and select sealants resistant to hydrolytic degradation.
  • Relevant for regulatory compliance, procurement specifications, and durability assessments of joint sealants subject to humid, high-temperature environments.

Related standards

  • EN 14187 series (Parts 1–9) - complementary test methods (rate of cure, tack-free time, fuel/chemical immersion, adhesion/cohesion, flame resistance, UV weathering, functional testing).
  • EN ISO 868 - Shore hardness measurement.
  • EN ISO 6927 - sealant vocabulary.
