1 Introduction
The K4585X dual purpose oven is designed to
determine the loss in weight of bitumen and flux oils
(loss on heating test) and the effect of heat and air
on asphaltic materials (thin film test). The unit is
heavily insulated and has a double glass door for
viewing the test chamber thermometer and samples.
Temperature is controlled at 163°C ± 1°C by means
of a variable temperature controller and thermostat.
Two rotating platforms are supplied with each oven:
one accepts nine standard penetration cups for the
loss on heating test, the other accepts two 140mm
diameter test pans for the thin film test. The
platforms are rotated at 5 to 6 rpm by an external
motor.
This manual provides important information
regarding safety, technical reference, installation
requirements, operating condition specifications,
user facility resource requirements, and operating
instructions for the K4585X. This manual should also
be used in conjunction with applicable published
laboratory
procedures. Information on these
procedures is given in section 1.2.
