A
Testtech
dispõe do que
há de melhor em equipamentos para
avaliação de
polímeros sob o aspecto de flamabilidade. Dispomos de
modernos
analisadores de Glow
wire e Tracking
Index .
Nosso equipamento para avaliação de Tracking
Index, por
exemplo, é totalmente automatizado e conectado à
intranet
da Testtech. Imediatamente após a conclusão do
ensaio os
dados obtidos já estão disponibilizados em nossa
rede
para processamento e geração do
relatório de
medição.
Tracking Index
IEC 60112 - Method for the determination of the proof and the comparative tracking index of solid insulating materials
• Determinação do CTI dos materiais isolantes
• Determinação do PTI (índice de resistência ao trilhamento) dos materiais isolantes201.54.129.89
• Ensaio do anexo N da IEC 60335-1 (4° edição) - Ensaio de resistência ao trilhamento
Índice comparativo de trilhamento (comparative tracking index)
CTI
numerical value of the maximum voltage at which five test specimens withstand the test
period for 50 drops without tracking failure and without a persistent flame occurring and
including also a statement relating to the behaviour of the material when tested using 100 drops (see 11.4)
Indice de trilhamento determinado (proof tracking index)
PTI
numerical
value of the
proof voltage in volts at which five test specimens withstand the test
period for 50 drops
without tracking failure and without a persistent flame occurring .
O equipamento utilizado na Testtech para análise de trilhamento é de última geração, completamente automatizado.

Fio Incandescente (glow-wire) IEC 60695-2-11
glow-wire flammability index (GWFI) …….. IEC 60695-2-12
The
test results make
it possible
to provide a relative comparison of various materials according to
their ability to extinguish flames on removal of the electrically
heated glow-wire and their ability not to produce flaming or glowing
particles capable of spreading fire to a specified layer of wrapping
tissue placed below.
glow-wire
flammability
index (GWFI):
Highest test temperature, during three subsequent tests for a test specimen of a given thickness, at which one of the following conditions are fulfilled:
a) flames or glowing of the test specimen extinguish within 30 s after removal of the glow-wire and there is no ignition of the wrapping tissue placed underneath the test specimen;
b) there is no ignition of the test specimen glow-wire ignition temperature (GWIT) ….. IEC 60695-2-13
The test results make it possible to provide a relative comparison of various materials according to the temperature at which the test specimen ignites during the application of the electrically heated glow-wire used as an ignition source.
glow-wire ignition temperature (GWIT):
Temperature which is 25 K (30 K between 900 °C and 960 °C) higher than the maximum temperature of the tip of the glow-wire which does not cause ignition of a test specimen of given thickness during three subsequent tests .
