Add To Cart

SFI & FIA are renowned sport racing safety certification councils. They operate differently yet their mission is the same. To maximize driver safety with current technology, science, tests, rules and minimum standards. Regarding fire retardancy standards, the SFI and the FIA both use TPP (Thermal Protective Performance) to correlate their fire ratings.

SFI 3.2A Spec is used for fire-retardant apparel. FIA will uses a code starting with 8856 followed by a date, which refers to the year the homologation was introduced. The most common current is 8856-2000. However we do know that the FIA is updating this standard.

Note: Please dismiss the common misunderstanding that a SFI 3.2A/5 suit means the suit has 5 layers.

To reach a TPP rating the suits material is subject to both a direct flame and a radiant heat measure. The thread, zippers, and cuffs also have to be tested.

For ease of understanding the TPP results are translated into seconds. That is seconds the fabrics prohibits the body from receiving a second degree burn.

SFI Rating TPP ValueTime to 2nd Degree Burn3.

2A/1 - 3 Seconds (TPP 6)

3.2A/3 - 7 Seconds (TPP 14)

3.2A/5 - 10 Seconds (TPP1 9)

3.2A/10 - 19 Seconds(TPP 38)

3.2A/15 - 30 Seconds (TPP 60)

3.2A/20 - 40 Seconds (TPP 80)

The radiant heat portion of the spec is significant because the majority of racer burns are caused by heat transfer rather than direct flame. Insulation is the best way to prevent this kind of burn. Using multiple layers of fabric helps keep the heat source away from the skin longer because each layer creates air gaps that have to heat up. The extra seconds gained with each layer are precious to a driver trying to escape from a burning car. (SFI Foundation)

How manufacturers achieved these TPP depends on the fabric, the construction and the numbers of layers used. A maufacturer has to submit samples of the fabrics as they will be used in the manufacturing process. Aramid suits’ fabrics are woven with fire-resistant threads such as Nomex (DuPont patented.) These are very expensive threads so companies weave the fabric with other organic materials such as cotton. However, the suit will not be so fire retardant so manufacturers have to add layers to achieve their desired TPP standard. This is why the less expensive suits are heavier. In auto racing less (weight) often meansmore (money.)

Other things to consider:

Keep your suit clean and do not wear while repairing your car. Grease, fuel, oils, fluids, and their fumes will soak into the fabric creating a conduit for fire, support the flames and lead to a combusible situation. We recommend using Molecule products to maintain and prolong the life of your suit.

Air layers increase the suits fire resistance. The suits quiltng is used for this. Tight suits take away air pockets. Adding fire-resistant underwear adds to the TPP. Certified underwear’s minimum TPP is 3 seconds and that’s in addition to the suit’s minimum TPP - and is increased by the air layer between the layers.

All suits pass the minimum TPP standard - the better brands surpass them. You are not just paying for that recognized logo.

Patches and similar should have a fire-retardant backing and be attached used Nomes thread.

Always follow the manufacturers instructions for the proper maintenance of your suit. In addition we recommend you do not hang the suit in the sun. UV rays are harmful to all aramid fabrics, plus damaging to the color. When not in use, or off season, hang the suit - not fold it.
