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

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.

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.
Instrumented mannequin test - ISO 13506Test 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)
