  • 1. Alsico Academy Different FR fabrics Same standards Different protection
  • 2. Different FR fabrics Same standards Different protection Karin Klein Hesselink TenCate Protective Fabrics EMEA
  • 3. Thermal hazards industrial safety • Welding sparks • Electric arc • Flash over • Explosion • Molten metal splashes • Aluminum splashes • Contact to hot surfaces
  • 4. EN ISO standards for thermal hazards industrial safety EN ISO 14116: 2008 Protective clothing - Protection against heat and flame - Limited flame spread materials, material assemblies and clothing EN ISO 11612: 2008 Protective clothing - Clothing to protect against heat and flame EN ISO 11611: 2007 Protective clothing for use in welding and allied processes EN IEC 61482-1: 2007 Live working - Protective clothing against the thermal hazards of an electric arc – Part 1-1: Test methods - Method 1 - Determination of the arc rating (ATPV or EBT50) of flame resistant materials for clothing Part 1-2: Test methods - Method 2: Determination of arc protection class of material and clothing by using a constrained and directed arc (box test)
  • 5. EN 11612 A1, B1, C1, E1 EN 1149-5 EN 13034 EN 61482-1-2. EN ISO 11612 A1/B1/C1/F1 EN 1149-5 EN ISO 11612 A1+A2 B1 C1 F1 EN ISO 11611 Class 1, A1+A2 Is this all the same?? EN ISO 11612:2009 A1-B1-C1-E3-F1 EN ISO 1611:2007 (A1: class1) EN 1149-5:2008 EN 13034: 2009 EN 11612 A1, B1, C1, E1 EN 1149-5 EN 13034 EN 61482-1-2. No EN 11612 A1, B1, C1, E1 EN 1149-5 EN 13034 EN 61482-1-2.
  • 6. Protective fabrics – Flame retardant technologies Flame-retardant finished fabrics • Flame retardant properties applied by a finish technology. Inherently flame-resistant • Flame retardant properties are build in the composition
  • 7. FR Finished About Inherent FR Non permanent fabrics flame retardant Flame retardant properties are build in Non FR fibers 100% FR fibers Mainly high amount of cotton fibers in the composition Synthetic fibers FR modacryl (PPANfr) and cotton based blends FR modacryl (PPANfr) and lyocell based blends Branded and Non-branded Branded and nonbranded Branded and nonbranded Patented FR Protection EN ISO 11612 EN ISO 11611 EN IEC 61482-1-1&2 EN ISO 11612 EN ISO 11611 EN IEC 61482-1-1&2 EN ISO 11612 EN ISO 11611 EN IEC 61482-1-1&2 EN ISO 11612 EN ISO 11611 EN IEC 61482-1-1&2 - Single flame Good Good Good Good - Flash over Poor - worse Good Poor - worse Very good - Welding Good (weight) Poor (weight) Poor - medium Medium- good - Electric arc Very good Good Very good Very good Blends of FR fibers and non-FR fibers
  • 8. Single flame • Part of EN ISO 11612 requirements • Limited Flame Spread EN ISO 15025 • 10 seconds of flame exposure • A1: surface flame test • A2: bottom edge flame test • Requirements • No flaming to the top or either side edge • No hole formation (Ø≤ 0.5 cm) • No melt or flaming or molten debris • After flame time shall be ≤ 2 s • Afterglow time shall be ≤ 2 s. Movie limited flame spread ISO 15025
  • 9. Results of different FR fabrics Cotton FR, 250 g/m2 Nomex® III, 260 g/m2 Mod FR/Cotton, 250 g/m2 Mod FR/ Lyocel, 240 g/m2
  • 10. Protection against flashover • A flashover can take place for example in the chemical, petrochemical or oil industry. • It occurs when gases and inflammable substances suddenly ignite. • Employees are exposed to an extreme progression of fire and blazing temperatures. • A flashover is short, unexpected but extremely powerful.
  • 11. Instrumented mannequin test - ISO 13506 Test method for flashover simulation • Heat sensors fitted to the surface of the mannequin • Mannequin dressed in garment is exposed to a simulated flashover. • Exposure time within the industry: 3 or 4 seconds, heat flux 84 kW/m2 • Test results indicate total heat transferred, percentage of burn injury, thermal shrinkage and visual examination of garment. • Comparative tests needs to be carried out by same test institute, based on same clothing design, size and test conditions. • Test institutes: EMPA, BTTG, NCSU, Aitex (and Dupont) • Requirement in the US standards NFPA 2112 • No normative aspect of ISO 11612, but informative Annex (C)
