Overview

EN 17333-5:2020 is a European standard developed by CEN that specifies standardized test methods for evaluating the insulation properties of one component foams (OCF). These foams include moisture curing, self-curing activatable, or water drying formulations dispensed from single pressurised foam containers. The primary focus of this standard is to establish reliable procedures to measure the long-term thermal conductivity of cured foam samples, ensuring consistent assessment of their insulation performance.

This part of the EN 17333 series addresses insulation characteristics, complementing other parts covering foam yield, expansion, application, and mechanical strength. It provides detailed methodology for preparing foam samples, conducting accelerated ageing, and measuring thermal conductivity, helping manufacturers, researchers, and quality control professionals to evaluate and compare foam insulation effectiveness.

Key Topics

• Scope of Application:
  EN 17333-5:2020 applies to moisture curing, self-curing, and water drying one component foams dispensed from pressurised containers. It focuses on determining the foam's insulation performance after curing.

• Thermal Conductivity Test Method:

  • Foam samples are prepared in specialized moulds composed of non-adherent plates and spacers.
  • The foam cures inside the mould, then samples are extracted and cut to specified dimensions.
  • Samples undergo accelerated ageing for 21 days at 70 ± 2 °C to simulate long-term conditions.
  • Thermal conductivity is measured using a thermal conductivity meter under standardized temperature gradients, referencing EN 12667 for test procedures.

• Sample Preparation and Conditioning:

  • Plates and spacers are conditioned at 23 ± 2 °C and 50 ± 5% relative humidity for 24 hours.
  • The inner sides of plates are moistened to ensure foam release and consistent curing.
  • The foam is applied in layers between plates and cured according to the foam type.
  • Larger or thicker samples follow modified preparation methods to prevent deformation.

• Reporting Requirements:
  Test reports must include comprehensive product information, testing conditions, measurement results, and any deviations from the procedure. This ensures traceability and reliability in thermal insulation evaluations.

Applications

• Building and Construction:
  Effectively evaluating the thermal insulation of OCF materials supports compliance with building energy efficiency regulations and enhances the performance of insulation joints, gap fillings, and structural sealing.

• Manufacturing Quality Control:
  Standardized insulation testing aids manufacturers in verifying the consistency and quality of foam formulations, ensuring products meet thermal performance claims over time.

• Research and Development:
  R&D teams can utilize the test methods to optimize foam formulations for improved insulation properties and durability under varied environmental conditions.

• Performance Certification:
  Testing as per EN 17333-5:2020 provides credible data for certifications and declarations related to insulation capacity, facilitating product acceptance in regulated markets across Europe.
