PROCEDURE 90110-0
CATALYSf Atry substance of which a fractional percentage notably affects the
rateAfz chemical rea_^*on without itself consumed or undergoing
-- - a chemical change.
COMPRESSIVE STRENGTH Th e maximum load per unit area that an object can withstand prior
to breaking.
SPECIMENS Cylindera of the solidified produce with the nominal dimensions: 1-
7/16' Dia, Z' Height These cylinders are used for the testing of
compressive strength.
DISSOLVED SOLIDS In an aqueous system, the relative percentage of the total solids that
exist in solution.
EXOTHERM A plot of the temperature versus time.
FINES Particles with a diameter less than 74 mierons, as determined by a
Tyler sleeve.
FREE STANDING LIQUID Liquid that is either.
1. Visible on the surface of a solidifieation sample.
2. Pours or leaks from a container upon the coetainen being
breached or punctured.
LAB SCALE Approximately one (1) gallon in volume.
ONSET The start of a reaction. When used in conjunction with the term
"exotherm', the start of the rise in temperature as a function of
time.
PARTS PER BILLION ppb 1 microgram per liter or one (1) mg per Itiloliter.
PARTS PER MILLION ppm 1 milligram per gram, one (1) g per liter.
PEAK The highest value attained. When used in conjunction with the
tertn 'exotherm'.the highest temperature achieved.
PLATEAU A region in the curve where 9X = 0.
