There is no "yellow UL card" for these semi-finished products.
Key
(1) According to method 1 of ISO 62 and
carried out on discs of ∅ 50 x 3 mm.
(2) Valid for just a few hours of temperature
stress for applications where no or only
low mechanical stresses occur.
(3) Temperature load capacity over at least
20.000 hours. After this time interval,
the tensile strength has dropped to
around 50 % of the initial value. The upper
service temperature limit listed here is
therefore based on the thermal oxidative
degradation that occurs, which causes
the property level to decrease. However,
in many cases the maximum permissible
service temperature primarily depends on
the duration and degree of the mechanical
stresses that arise during the application
of heat.
(4) Please note that under no circumstances
may conclusions regarding the behaviour
of the materials in an actual fire be drawn
from these estimated values taken largely
from the material sheets provided by
the raw-material suppliers. There is no
"yellow UL card" for these semi-finished
products.
(5) Test specimen: type 1 B.
(6) Test speed: 5 mm/min.
(7) Test speed: 1 mm/min.
(8) Pendulum impact tester used: 4 J.
(9) Measured on test specimens 10 mm thick.
(10) Measured on test specimens 1 mm thick.
It is important to know that the dielectric
strength of KETRON PEEK 1000 black
can be up to 50 % lower than that of the
natural-coloured material.
