Arc Flash & Protective Clothing Standards

BS EN ISO 14116 standard for ‘Protection Against Heat & Flame, Limited Flame Spread’ replaces the withdrawn EN533. While the standard does deal with the issue of flame resistance to some extent, it is arguably more suited to outerwear that would usually be worn over other protective garments. For this reason ProGARM have opted to rather meet EN11612 which offers a higher standard of protection.

Clothing manufactured to this standard is made from flame retardant materials so that if the material comes into contact with a flame, it will only continue to burn for a limited amount of time. After removal from the flame, the material will stop burning. Clothing in this category should not be worn to protect against convective heat, radiant heat, molten metal or similar higher risk hazards.

THE CONTENTS OF THIS STANDARD

For fabrics, this standard only has a flame spread test and the test results are given as Index values as detailed below. The number of wash cycles and the washing method used to achieve the stated index value are also given under the EN Standard pictogram. E.g. “25H” indicates 25 domestic wash cycles (this can also be indicated as “I” for industrial wash cycles or “C” for chemical cleaning such as Dry Cleaning). The “60” represents the laboratory washing temperature in degrees Celsius. There are also requirements in this standard for the seam strength to be tested and for tests to ensure the flame retardant properties of the garment’s seams meet the requirements.

Different tests, codes

Index 1: No flaming to the top or side edge, no flaming debris and no afterglow shall spread from the carbonized area to the undamaged area. Hole formation is possible under this Index. These fabrics should not be worn next to the skin. An example of a fabric in the category would be an FR polyester which will meet the requirements but will always form a hole.

Index 2: No flaming to the top or side edge, no flaming debris and no afterglow shall spread from the carbonized area to the undamaged area. No hole formation possible with this Index. The requirements are the same as Index 3 but no maximum afterflame time is specified.

Index 3: Requirements are the same as Index 2, but the Afterflame time of each individual specimen should not exceed 2 seconds.


BS EN ISO 14116 | Standard Overview

Protective clothing. Limited flame spread. Prevent protective clothing catching fire.

BS EN ISO 14116 specifies performance requirements for the limited flame spread properties of materials used in protective clothing to reduce the possibility of clothes burning.

Protective clothing complying with BS EN ISO 14116 is intended to protect workers against occasional and brief contact with small igniting flames, in circumstances where there is no significant heat hazard and without the presence of another type of heat. When protection against heat hazards is necessary in addition to protection against limited spread flammability, then standards, such as BS EN ISO 11612 are more appropriate.

A classification system is also given for materials, material assemblies and garments which are tested according to BS EN ISO 15025 Procedure A.

This standard has been revised to:

  • Include test procedures for burst strength testing of woven materials
  • Include new definition for determination of hole formation
  • Modify clause in design requirements regarding garment overlaps
  • Modify clause on sampling requirements
  • Modify pre-treatment clause to include requirements for single use garments
  • Modify clause for aging due to washing
  • Include new requirement for measuring property value for rating and classifications
  • Modify test procedure for the flame testing of labels, badges and retro reflective materials
  • Include test procedure for testing of hardware and for tensile strength testing of non-woven materials
  • Modify flame spread definition and flaming debris
  • Modify afterglow requirement for flame spread of Index 1,2 and 3 materials
  • Include normative Annex for uncertainty of measurement and for measuring property value for rating and classification
