The Pensky-Martens Flash Point Tester
conforms to ASTM D-93 and is designed
to determine the flash point of fuel
oils, lube oils, suspensions of solids,
liquids that
tend to form a surface
film under test conditions, and other
liquids.
Installation and Operation
ASTM D-93 outlines the installation and
operational
procedures
required
for
the determination of flash points and
should be referred to in all cases.
ASTM methods can be obtained from:
American Society for Testing Materials

SAFETY CONSIDERATIONS AND WARNINGS:
The following guidelines are presented
to supplement the existing safety rules
enforced by your company:
1)
Safety glasses should be worn by
the operator and by anyone in the vicin-
ity who could be splashed by liquid
samples.
2)
It is recommended that a fire ex-
tinguisher of Halon 1211 or CO2 (at
least a 5-1b. tank size) be placed con-
veniently in reach of the operator to
protect against fires caused by the
sample which might accidentally ignite
during test.
3)
Service or circuit testing should
be attempted only by a qualified person
who has been trained with regard to the
potential danger of working with live
electrical circuitry.
WARNING :
Disconnect the unit
from the power source whenever
replacing electrical
components.
Electrical Connections:
Important
(Please Read Carefully.)
The services of a qualified technician
should be used to install this unit.
It should be determined that the power
supply receptacle is properly polarized

As delivered,
it is supplied with a
standard three-wire polarized line cord
and plug for operation on 120 volts,
single phase, 50/60 Hertz, or 220V,
50/60 Hertz.
When a two-prong wall receptacle is
encountered, it is the personal respon-
sibility and obligation of the installer
to have it replaced with a properly
grounded three-prong receptacle.
WARNING: DO
NOT ,
under
any
circumstances,
cut or
remove
the third (ground) prong from
the power cord.
DO NOT use a
two-prong adapter plug.
