What is the name of
the standard?
*6 CFR
***1:Standard for the flammability of vinyl plastic
film
What ranges does it
apply to?
The rate of burning
shall not exceed 1.2in/sec as judged by the average of five
determinations lengthwise and five determinations transverse to the
direction of processing,when the material is tested with the SPI
flammability tester in accordance with the method described in
***1.4.
What are the sample
requirements?
Test specimens shall
be 3 in.in width and 9 in.in length.They shall be free from folds
or wrinkles. Five specimens from each direction(machine and
transverse)of a given material shall be
tested.
What testing methods
are required?
(1) Put the sample
in the test equipment for fire test as
required
(2) Calculate the
average combustion rate of 5 transverse samples and the average
combustion rate of 5 longitudinal samples, if the burning rate
exceeds 1.2 inches per second, the result is considered to be a
failure.
(3) At least two
samples ignite and burn the limit line of the specimen. If less
than two of the five specimens in any given five specimens ignite
and burn the specimen limit line, the following results are
given:
A: If there is no sample ignited and burned the
limit line, the result of the group of samples is deemed to
pass;
B: If only one
specimen ignites and burns the limit line, the result is regarded
as unqualified;
What other standards
are there?

Films
