Safety standards are an essential part of auto racing.
Safety standards offer a required guaranty of basic protection to the various participants (drivers, crew, track personnel, rescue team...). Sanctioning bodies or specialized non-profit entities establish safety standards and the tests a product must undergo to earn their safety label. Such tests consist in timed flame exposure, applied pressure on a product or its components, resistance to various impact types from different angles… Samples of each product (according to size, options, etc.) are sent by the manufacturers to test laboratories approved by the sanctioning bodies, certification being granted if the given product exceeds the required standards. Here is a summary of the most commonly used and most stringent standards for the racing suits.
FIA 8856-2018
SFI 3.2A/20 SFI 3.4/5 SFI 3.2a/5
- It is forbidden to change the raw material and manufacturing of the racing suit
- Design elements (stripes, piping…) must be made in aramid fabric (ISO 15025A standard)
- Shoulder pads are compulsory
- Embroideries must be solely put on the outside layer of the racing suit
- Badges backgrounds must comply with the ISO 15025A standard and be fireproof

The TPP test (Thermal Protective Performance)
exposes the fabric to a standard heat and measures the thermal energy quantity which, applied on the fabric, will lead to a second-degree burn on the skin when in contact with the other side of the fabric.
SFI 3.2A Level 5 homologated racing suits
(close to FIA 8856-2000 homologated racing suits performance-wise) must get a TPP result of 19.
The TPP to get the SFI 3.2A Level 20 standard is 80.
The TPP for Dragster racing suits by Stand 21 Level 20
are: 5 layers = 95
       6 layers > 100
Where required


Used in FIA sanctioned races in Europe, Australia and Asia.

- Level 20: used for drag racing in Top-Fuel  and Funny Cars classes
- Level 15 : used for straight-line speed records, lower drag racing classes
- Level 5 : used in most other forms of racing in the U.S.A. and Canada run under SFI standards
