• EN 15614

    Paragraph 4 of this norm describes the design of the suit. A few examples:

    • Fastening systems to avoid the penetration of burning residues
    • The collar has to remain upright
    • No cuffs in tricot
    • A fastening system that bridges the border of the trousers and the boots
    • Sleeves with a fastening system.

Paragraph 5 prescribes that the garment has to be washed (at least 5 times) according to the instructions of the manufacturer before certification.

The radiant heat test is defined in paragraph 6.3 by the (EN ISO 6942) with a heat flux of 20kW/m². The fabric or the assembly has to present an RHTI24 that is higher than 11 seconds with a RHTI24-RHTI12 differential of more than 4 seconds.

In addition, all the components, such as badges and fasteners are tested for 5 minutes at a temperature of 180°C according to the (ISO 17493) standard. The sewing thread can't melt at a temperature of 260°C.

The fabrics and the confection also have to respect several mechanical criteria:

  • The outer fabric has to present a tensile strength that is higher than 450N (ISO 13934-1) and a tear strength of more than 20N (ISO 13937-2).
  • The principal seams also have to offer a resistance of at least 225N (ISO 13935-2).

In addition, to guarantee an excellent comfort, the fabric or the assembly has to have a thermal resistance of ≤ 0,055 m².K/W (EN 31092) and a water vapour resistance of ≤ 10m².Pa/W (EN 31092) for a good breathability.

Finally, the garment has to present at least 0,13m² of retroreflective material (EN 20471) or at least 0,2 m² if the material has combined characteristics.
