WARNING
The following test involves the use of intense heat. Failure to follow appropriate
procedures or warnings can cause burns which can result in severe personal injury.
While performing the following test, observe these general precautions:
•
Wear personal protective clothing such as rubber gloves, a non-flammable
apron, and eye protection - preferably full face shield or safety glasses.
•
The appropriate heat source should only be electric. Heat source should be
operated by a qualified person. Be sure to follow all instructions of the
manufacturer of the heat source. The heat source should be checked each time
it is used to be sure it is functioning properly.
•
The thermometer used in the test should be a high-temperature thermometer
with a maximum reading of at least 300°F (150°C). Under no circumstances
should the operator allow temperatures to exceed test specifications.
•
•
Perform test only in a well ventilated area.
Use a suitable container, such as metal, to hold the water. Avoid use of glass
containers unless the operator first confirms for himself/herself that the glass
container is an appropriate high-temperature vessel.
•
Because the components will reach high temperatures DO NOT handle materi-
als or components until COMPLETELY cooled.
