2.1.1.3
Flame Resistance
**************************************************************************
NOTE: UL 214 and NFPA 701 include small and large
scale test procedures. The large scale test is more
severe than the small scale test. UL 214 requires
that all fabrics meet the performance requirements
of both tests. NFPA 701 provides for optional use
at the discretion of the authority having
jurisdiction. National Fire Protection Association
101, "Code for Safety to Life from Fire in Buildings
and Structures", requires both tests for fabrics
used in assembly, educational, health care,
detention and correctional, and residential
occupancies.
For other occupancies, the large scale test should
be specified only when stringent flame resistance
requirements are necessary, or when the nature of
the fabric specified is such that excessive melting
or shrinkage will render the small scale test
ineffective. Otherwise, the small scale test
requirements are adequate in most cases.
A variety of flame-retardant treatments are
available. Generally, they fall into two broad
categories: (1) permanent type, and (2) the less
expensive, renewable type. Permanent treatments
retain their effectiveness through a number of
