1 SFI SPECIFICATION Page 1 Effective: March 27, 2013 Copyright 2013 by the SFI Foundation, Inc. All rights reserved. Reproduction in any form without written permission of SFI is prohibited. SFI SPECIFICATION EFFECTIVE: MARCH 27, 2013* PRODUCT: Driver Suits GENERAL INFORMATION This SFI SPECIFICATION establishes uniform test procedures and minimum standards for evaluating and determining performance capabilities for Driver Suits used by individuals engaged in competitive motorsports. The procedures, test evaluations and standards contained herein, are intended only as minimum guidelines for construction and evaluation of products. Certification that products meet such minimum standards is made by the product manufacturer and products are not certified, endorsed or approved by SFI under this program. Use of the "This Manufacturer Certifies That This Product Meets SFI SPECIFICATION " logo/designation, the authorized artwork style, or conventional lettering by a manufacturer, on a subject product, is intended only to indicate that the manufacturer of the product has represented that they have submitted the product to the recommended tests, with positive results, in compliance with the standards established herein.

2 This SFI SPECIFICATION requires a demonstration that the product of a manufacturer meets or exceeds the requirements when the manufacturer enters the program; and on a periodic basis thereafter. Any manufacturer may participate in the program by providing Driver Suits that meet or exceed the SFI SPECIFICATION test standards, by complying with the requirements of the SFI SPECIFICATION program, and by signing a licensing agreement with the SFI Foundation, Inc. Compliance with this SPECIFICATION is entirely voluntary. However, when a manufacturer provides Driver Suits in compliance with all requirements of the SFI SPECIFICATION and enters into the licensing agreement with the SFI SFI SPECIFICATION Page 2 Effective: March 27, 2013 Copyright 2013 by the SFI Foundation, Inc. All rights reserved. Reproduction in any form without written permission of SFI is prohibited.

3 Foundation, Inc., they may certify that compliance with such standards is in accordance with the guidelines established herein. Manufacturers wishing to participate in the program, in addition to the other requirements of this SPECIFICATION , must label each of their products with the manufacturer's name, trademark or symbol as well as the date of manufacture of the product. No manufacturer may display the SFI logo/designation on their product unless the manufacturer has signed a licensing agreement with SFI and has successfully complied with all the requirements of this SPECIFICATION and the self-certification program. DEFINITIONS Driver Suit: A uniform made out of fire resistant/retardant material that is used for fire protection in competitive motorsports. All cuffs (wrists and ankles) shall be made out of fire resistant/fire retardant material. Suit Layer or Layer: Any single woven, non-woven, knitted, or felted flame resistant/retardant cloth.

4 Excluding any combinations, composites or assemblies of single fabrics. Multiple Layers: Driver suit material can be constructed of a single layer or multiple layers of fabric. A suit's rating is based on the thermal protection capability of the material regardless of the number of layers. The use of underclothing is not considered in the rating of the suit. Closures: All closures (metal zipper or Velcro) shall be of fire resistant/fire retardant construction. The zipper closure shall be constructed of metal teeth and fire retardant tape. Any velcro closure must be covered by fire retardant/fire resistant material. Each or higher level "manufacturer certified" driver suit shall be inspected every five years by the "certifying manufacturer" for re-certification. After inspection, when the suit is determined to be acceptable for continued service, a new conformance label marked with the year of inspection shall be used.

5 All expansion and/or comfort gusset material, if used, must be tested and must meet the same minimum TPP rating as the entire driver suit. Associated Apparel: Gloves, underclothing, hoods, socks, shoes and helmet supports may be associated with a driver suit but are not rated by this SPECIFICATION .

Embroidered logos are permitted and do not inadvertently affect the performance or rating of the garment. CONSTRUCTION Driver Suits can either be a one-piece coverall type, a two piece traditional type, consisting of a jacket and pants, or just a jacket. A two piece suit must have an eight-inch overlap in the waist area as a minimum. Any flame retardant chemicals, that by their nature, application and/or chemistry would not be expected to survive exposure to water, "non-durable finishes" are not acceptable for use on materials qualified for "manufacturer certified" Driver Suits constructed in accordance with the guidelines of this SPECIFICATION .

6 All material layers in a driver suit must fully extend all the way to all seams. The shortening of any layer prior to the seam is not permitted. MODEL CLASSIFICATION If all other factors remain the same, Driver Suit models are not a function of size or color. TESTING TPP RATING Test in accordance with SFI Technical Bulletin At least four samples shall be supplied. FLAMMABILITY Driver Suits Test each individual suit layer (single and multiple layer levels) as defined in Section in accordance with SFI Technical Bulletin Cuffs (wrists and ankles) Test in accordance with SFI Technical Bulletin THREAD HEAT RESISTANCE All driver suits that are required to undergo the TPP test shall be subjected to this test. The test shall be conducted in accordance with FTM 191-1534 unless otherwise specified. SFI SPECIFICATION Page 4 Effective: March 27, 2013 Copyright 2013 by the SFI Foundation, Inc.

SAMPLES The sample material shall be identical to the thread used in the actual construction of the driver suit. Sufficient material for at least three tests shall be supplied. PRECONDITIONING Samples shall be conditioned at a temperature of 21 1 degrees Celsius { C} (70 2 degrees Fahrenheit { F}) at a relative humidity of 65 5 percent for one hour. Samples shall be tested not more than five minutes after removal from conditioning. PROCEDURE Conduct the test three times. The samples shall be tested to a temperature of 260 2 degrees Celsius { C} (500 4 degrees Fahrenheit { F}). ZIPPER HEAT RESISTANCE TEST SAMPLES The sample material shall be identical to the zipper and fire retardant tape used in the actual construction of the driver suit. Specimen length shall be at least 6 inches (152mm).

8 PRECONDITIONING Samples shall be conditioned at a temperature of 21 1 degrees Celsius { C} (70 2 degrees Fahrenheit { F}) at a relative humidity of 65 5 percent for one hour. Samples shall be tested not more than five minutes after removal from conditioning. PROCEDURE The forced circulating air oven shall achieve and maintain an air temperature of 260 3 degrees Celsius { C} (500 10 degrees Fahrenheit { F}) for a period of not less than 5 minutes. Oven recovery time after the door is closed shall not exceed 90 seconds. The specimen shall be suspended by metal clips at the top and centered in the oven so that the entire specimen is not less than two (2) inches ( mm) from any oven surface or other specimen, and airflow is parallel to the plane of the material. Specimens, mounted as specified, shall be placed in the circulating air oven for 5 minutes, + minutes.

9 Specimen exposure time shall begin when oven SFI SPECIFICATION Page 5 Effective: March 27, 2013 Copyright 2013 by the SFI Foundation, Inc. All rights reserved.
