2. grind the specimens at a contact pressure of 40 to 150 kpa on a bonded diamond platen for approximately 60 s or until the exposed surface of each specimen is ﬂat and clean. note that the pressure indicated on the grinding machine gage is usually the incoming air pressure, which is not necessarily equal to the pressure of the specimens,12 laboratory sample preparation,grinding and crushing (dean, 1995). decreases in water content are sometimes observed while grinding solids containing essential water in the form of hydrates, likely as a result of localized heating. (see section 18.104.22.168 for a discussion of the types of moisture present in solid samples.)
