Time of Setting Determination—Allow the time of
setting specimen to remain in the moist cabinet or moist room
for 30 min after molding without being disturbed. Determine
the penetration of the 1-mm needle at this time and every 15
min thereafter (every 10 min for Type III cements) until a
penetration of 25 mm or less is obtained. Perform the penetration
test by lowering the needle D of the rod B until it rests on
the surface of the cement paste.
