SECTION A
GENERAL INSTRUCTIONS
(A) Place silver casting on heater as shown and attach with 4 #8 X 1/2 pan head sheet metal screws
provided.
(B) Place item 5 in casting, as shown in drawing, and screw item 6 onto it. Tighten, using one 9/16 wrench
and one 5/8 wrench and secure firmly.
(C) To assemble the flame test burner, remove the 2-56 screw first from the burner support (Item 5) and
attach the flame test burner assembly. Reinstall the 2-56 screw and secure firmly. Unit is now ready for
operation.
3. OPERATING INSTRUCTIONS: (Per ASTM D92)
(A) All tests should be made in a room free of excessive drafts. The room or compartment should be
darkened sufficiently to allow the flash to be readily seen, and the operator should avoid breathing over the
surface of the test oil.
(B) Suspend the thermometer in a vertical position by the thermometer holder (Item 2) so that the bottom of
the bulb is ¼ ” from the bottom of the cup, and a point half way between the center and back of the cup.
(C) Fill cup with the oil to be tested in such a manner that the top of meniscus is exactly at filling line at
ambient temperature.
(D) Viscous samples should be heated until they are reasonably fluid before being poured into the cup;
however the temperature during heating must not exceed 100°F below the probable Flash Point.
(E) Use a test flame approximately 5/32 of an inch in diameter, the same six as the flame guide. Adjust valve
(Item 11 on assembly drawing), if needed, until flame compares to the flame guide.
