Labels - ANSWER-written information printed on paper as packaging or glued, affixed,
sewn or stapled onto a fabric or product, or attached with a plastic extruded loop as a
hang tag onto furniture
breaking strength - ANSWER-the measurement of stress exerted to pull a fabric apart
under tension
smoldering - ANSWER-combustion without a flame that generates heat, smoke, and
toxicants and results in black charred damage
heat barrier - ANSWER-a liner between upholstery and padding to prevent flame spread
or smoldering heat
fabrication specifications - ANSWER-forms and written instructions often accompanied
by drawings that are given to a fabricator whose job it is to custom upholster or sew
textiles into the various applications
wet and dry crocking - ANSWER-transfer of dye from the surface of a dyed or printed
fabric onto another surface by rubbing
Pilling - ANSWER-the formation of fuzzy balls of fiber on the surface of a fabric that
remain attached to the fabric
reference standard - ANSWER-where the specs follow guidelines from an
acknowledged authoritative source or organization that has established a minimum
standard of quality that is acceptable for nonresidential interior design
Colorfastness - ANSWER-a measure of how permanent a color is on fabric
Abrasion - ANSWER-the surface wear of a fabric caused by rubbing and contact with
another fabric
seam slippage - ANSWER-the movement of yarns in a fabric that occurs when it is
pulled apart at a seam
specifications - ANSWER-the parameters for selecting a textile as written by the
architectural firm for contract or nonresidential design projects; entails the forms and
action of ordering of textile yardage, the fabrication sheets or forms whereby that
yardage is made into product and the installation forms and instructions

are thus easily managed
Proprietary spec - ANSWER-a specific product, identified by its brand name or number
from a specific manufacturer

given a flame resistant finish that resist flame or terminate the flame following ignition
char length - ANSWER-a measurement from the ignition source to the end of the burn

California Technical bulletin #116 and #117 - ANSWER-A vertical flame test measuring
the ease of ignition and the burning rate when a small open flame hits the surface of the
test fabric for 1 second. A Class 1 (pass) rating is assigned if:
1. a 5" section of the fabric is consumed in 3.5 seconds or more seconds (less than 3.5
seconds is a failure).
2. The fabric does not ignite.
NFPA 701 - ANSWER-A test method which measures the ignition resistance of a fabric
after it is exposed to a flame for 12 seconds. The flame, char length, and flaming
residue are recorded. The fabric will pass if all samples meet the following criteria:
1.An after flame of less than 2.0 seconds
2.An average char length of less than 6.5" or an individual specimen over 7.5"
The specimen does not continue to flame after reaching the floor of the test chamber
The Steiner Tunnel Test (ASTM E 84-03) - ANSWER-the most used widely procedure
to determine the surface burning behavior of building materials used for exposed
surfaces, such as ceilings or walls or floors.
