Material specications
UL ammability ratings
Flammability ratings for selecting cable ties
Note: Flammability ratings of cable tie materials per UL as
follows. These tests for ammability of plastic material are in-
tended to serve as a preliminary indica tion of acceptability with
respect to ammability for particular applications.
UL 94 vertical burn test procedures
Test specimens of the material, with dimensions 127 x 12.7 mm
(5»x 1/2»), with the thickness intended for use in the end product,
are tested in both the manufactured condition and in the aged
state. The test requires that the specimen be supported in a
vertical xture and a precisely controlled ame applied for a
10 second period. The ame is removed and the duration of
aming is noted. If the ame extinguishes, a second exposure
to ame for 10 seconds is applied and duration of aming is
again noted. It is observed and recorded whether or not test
specimens drip am ing particles that ignite a cotton swab.
Materials classed 94 V-0:
A material classed 94 V-0 shall:
A Not have any specimens that burn with am ing combus-
tion for more than 10 seconds after either application of
the test ame
B Not have a total aming combustion time exceeding 50
seconds for the 10 ame appli cations for each set of ve
specimens
C Not have any specimens that burn with aming or glowing
combustion up to the holding xture
D Not have any specimens that drip am ing particles that
ignite the dry absor bent surgical cotton located 304.8 mm
(12») below the test specimen
E Not have any specimens with glowing combustion that
persists for more than 30 seconds after the second re-
moval of the test ame
Materials classed 94 V-1:
A material classed 94 V-1 shall:
A Not have any specimens that burn with aming combus-
tion for more than 30 seconds after either application of
the test ame
B Not have a total aming combustion time exceeding 250
seconds for the 10 ame applications for each set of ve
specimens
C Not have any specimens that burn with aming or glowing
combustion up to the holding xture
D Not have any specimens that drip am ing particles that
ignite the dry absorbent surgical cotton located 304.8 mm
(12») below the test specimen
E Not have any specimens with glowing combustion that
persists for more than 60 seconds after the second re-
moval of the test ame.
Materials classed 94 V-2:
A material classed 94 V-2 shall:
A Not have any specimens that burn with aming combus-
tion for more than 30 seconds after either application of
the test ame
B Not have a total aming combustion time exceeding 250
seconds for the 10 ame applications for each set of ve
specimens
C Not have any specimens that burn with aming or glowing
combustion up to the holding xture
D Be permitted to have specimens that drip aming particles
that burn only briey, some of which ignite the dry ab-
sorbent surgical cotton placed 304.8 mm (12») below the
test specimen
E Not have any specimens with glowing combustion that
persists for more than 60 seconds after the second re-
moval of the test ame
UL 94 horizontal burn (HB) test procedures
The test uses a 1/2 inch x 5 inches (12.7 mm x 127 mm)
specimen held at one end in a horizontal position with marks
at 1 inch (25.4 mm) and 5 inches (127 mm) from the free end.
A ame is applied to the free end for 30 seconds or until the
ame front reaches the 1 inch (25.4 mm) mark. If combustion
continues the duration is timed between the 1 inch (25.4 mm)
mark and the 5 inch (127 mm) mark. If combustion stops be-
fore the 5 inch (127 mm) mark, the time of combustion and the
damaged length between the two marks are recorded. A set of
three specimens are tested.
Materials classed 94 HB
A material that is less than 0.118 inch (3 mm) in thickness will
be classied 94HB if it has a burning rate of less than 3 inches
(76.2 mm) per minute or stops burning before the 5 inches
(127 mm) mark. If one specimen from the set of three fails to
comply, then a second set of three are tested. All three of this
second set must comply. HB rated materials are considered
“self-extinguishing”. This is the lowest (least ame retardant)
UL94 rating.
Nylon 6.6 = Polyamide 6.6 is Halogen-free and Silicone-free.
