Tracking Test Apparatus Flammability Leakage Test Equipment
IEC60065
Introduction:
TRACKING TEST APPARATUS is intended for determining the degree of
protection against formation of conducting paths in solid
insulating materials, due to the electric stress and electrolytic
contamination of the surface.
This test is complex and the person performing it should be
accurate and maintain good cleanliness of test equipment. The
repeatability and comparability of test results depend on many
different factors. Therefore we designed TRACKING TEST APPARATUS
with the following goals:
- Reliability
- Maximum repeatability of test results
- Maximum comparability of test results
- Ease of operation
- Ergonomical design

Main Features:
—Self contained cabinet with large viewing window and internal
light
—Easy access to testing area during setup
—Built in exhaust fan
—Control panel has all controls in easy reach including lighting
and exhaust
—Platinum Electrodes 99.5% minimum purity
—Alarm sounds if tracking failure occurs for more than 2 seconds.
—Safety interlock on door halts test if the door is opened
—Easy adjustment to test table height
Description:
The Tracking Tester is a fully automatic instrument contained in
its own cabinet to maximize the safety of the operator. Inside the
well lit cabinet, a test specimen is placed on a glass plate and
two platinum electrodes are lowered onto the top surface. A gauge
block is supplied with the instrument to ensure the electrodes have
the proper distance between them. The table height is easily
adjustable to ensure the proper angle of the electrodes and height
of drops. The rest of the test is controlled from outside the test
chamber with the door closed. The voltage, limiting current, drip
rate and number of drips are all set on the control panel. An
operator should observe the test to see if a flame ignites. The
instrument sounds an alarm if there is a tracking failure of at
least two seconds.
