Fire Hazard Assessment of Rail Transportation Vehicles1
This standard is issued under the fixed designation E 2061; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
The traditional approach to codes and standards is the specification of individual fire-test-response
requirements for each material, component, or product that is found in a given environment and is
deemed important to maintain satisfactory levels of fire safety. This practice has been in place for so
long that it gives a significant level fort; manufacturers know what is required ply with
the specifications and specifiers simply apply the requirements. The implicit assumptions are not
stated, but they are that the use of the prescribed requirements ensures an adequate level of safety.
There is no need to impose any change on those manufacturers who supply safe systems meeting
existing prescriptive requirements; however, as new materials, components, and products are
developed, manufacturers, designers, and specifiers often desire the flexibility to choose how overall
safety requirements are to be met. It is the responsibility of developers of alternative approaches to
state explicitly the assumptions being made which result in a design having an equivalent level of
safety. One way to generate explicit and valid assumptions is to use a performance-based approach,
based on test methods that provide data in engineering units, suitable for use in fire safety engineering
calculations, as this guide provides.
This fire hazard assessment guide focuses on rail transportation vehicles. Such a fire hazard
assessment requires developing all crucial fire scenarios that must be
