DOCKET 90 Federal Transit Administration (FTA) Recommended Fire Safety Criteria for Transit Buses and Vans

DOCKET 90, published by the Federal Transit Administration (FTA), includes recommended fire safety criteria for public transit buses and minibuses. This document describes the following two basic test methods to evaluate the flammability and smoke emission properties of upholstery fabrics used in these vehicles:

• FAR 25.853 Fire test on aircraft material. This standard describes a vertical flammability test method designed to determine the material's resistance to flame ignition. While testing, the sample is held in a vertical position under the flame ignition source for a specified period of time. After the flame is removed, the sample is evaluated according to its ignition time, flame time, dripping flame time and burning length.
• ASTM E662 Standard test method for the specific optical density of smoke produced by solid materials. This standard describes a test method that measures and describes the response of materials, products or assemblies to heat and flame under controlled conditions. This fire test-response standard covers the determination of the specific optical density of smoke produced by vertically mounted solid materials and assemblies in thicknesses up to and including 25. Measurement of the attenuation of a light beam by smoke accumulated by non-flammable pyrolytic decomposition and flaming combustion in a closed chamber is made. Results are expressed in terms of specific optical density derived from a geometric factor and measured optical density, which is a measurement property of smoke concentration.

The main concern of material components used in public transport is their behavior during ignition, both in terms of flammability and smoke emission. Advanced labs meet stringent performance requirements for both test methods above and are documented as Docket 90 compliant.

In short, Docket 90 is a flammability and smoke emission certificate and is primarily concerned with the flammability and smoke emission characteristics of transit bus and pickup truck materials.

Among the numerous test, measurement, analysis and evaluation studies it has given for businesses in various sectors, our organization, with its trained and expert staff and advanced technological equipment, fire test within the scope of the fire safety criteria recommended for DOCKET 90 Federal Transit Administration (FTA) public transport buses and minibuses. also provides services.
