Ch 5- Interior Finishes and Passive Fire Protection Flashcards
Exposed interior surfaces of buildings, including fixed or movable walls and partitions, columns, and ceilings
Interior finish
Interior finish is also known as….
Interior lining
Name 3 fires that greatly influenced fire codes and proved interior finishes can contribute to loss of life?
LaSalle Hotel, Beverly Hills supper Club, Stations Night Club
Interior finishes may be classified as trim if they meet what conditions?
Do not exceed ten percent of the wall and ceiling area, Distributed through the space, Do not constitute a large continuous surface
Define flame spread?
Movement of a flame away from the ignition source
Define Surface-Burning Characteristic?
Speed at which flame will spread over the surface of a material
Define Compartment?
Any enclosed space without internal fire barriers
What is considered when evaluating for flame spread?
Composition, orientation, and thickness
Ventilation
Shape and size of a compartment
Finish material on the ceiling or wall
What is the most significant factor that determines a fuel burn rate?
Combination of the fuel and the available oxygen
Does a thin product of 1/4” or less propagate flame faster attached to non combustible material or attached to studs with air space behind it?
Attaching to studs with air space allows faster flame progression
Define Listed
a device or material that has been tested by any of several testing laboratories
What are the main testing laboratories
Underwriters, Factory mutual system
Define Intumescent coating
Coating or paintlike product that expands when exposed to the heat of a fire
What creates an insulating barrier that protects the material underneath by expanding when exposed to heat?
Intumescent coating
Define Mastics
heat resistant construction adhesive that bonds with most materials
What can be used as a flame retardant coating
Mastics
What are the four types of fire-retardant coatings?
Intumescent, Mastics, Gas-forming paints, cementitious and mineral fiber coatings
Measurement of one components tested performance against a set standard of criteria, not against similar components or assemblies
Criterion-Referenced Testing
Criterion-Referenced Testing is also known as?
Criterion-Referenced assessment
ASTM E-84
Standard test used to measure the surface burning characteristics of various materials
What is ASTM E-84 also known as?
Steiner Tunnel Test or Tunnel Test
Steiner Tunnel
Test apparatus used in the determination of flame spread ratings
Numerical rating assigned to a material based on the speed and extent to which flame travels over its surface
Flame spread rating
Measurement of the propagation of flame on the surface of materials or their assemblies as determined by standard tests
Flame spread rating
