If the approximate melting point of the specimen is not known before testing, it shall be determined by a tr
20、ial run. Place the specimen in a small mound between two cover glasses. Press the cover glasses together gently but firmly and place them in the circular depression stage. Raise the temperature of the stage with some rapidity to within 15C of the expected melting point and thereafter at a rate of 3
21、to 4“C/min. At this rate of temperature rise, apply a slight pressure on the upper microglass cover by pressing with a spatula or pick needle. Observe the specimen with the Mode opratOire - Prchauffer le banc au moins au point de fusion prvu du spcimen et le refroidir environ 50C sous ce point. Si l

In subsequent determinations, the stage in each case shall be cooled to approximately 50C below the expected
