Solid Specic Gravity Measurement for Lighter than Water
Solids (1 g/cm
3
or less)
Two different methods are available for solid specic gravity measurement for lighter than water
solid (1 g/cm
3
or less) samples.
Method 1: Measurement using a medium with a specic gravity lower than the solid specic
gravity
(Ex.: Ethanol 0.8 g/cm
3
)
This method is used when the solid density is only slightly different than the density of distilled
water.
Do not use ethanol if the solid sample will be affected by or react with ethanol.
It is necessary to strictly abide by all safety related regulations when
handling ethanol.
Method 2: Measurement using a submersion basket for a solid sample which oats on water
rather than placing the sample on the underwater weighing pan.
� Carry out "solid specic gravity measurement" and enter the medium parameters.
(^ Refer to P.91 to 92 steps 5 and 6)
� (^ P91) Refer to the procedures for solid specic gravity measurement, and set the sample
with the underwater weighing pan already submerged. If the sample buoyancy pushes the
underwater weighing basket upward, place a dummy weight on the pan and tare the weight of
the dummy when weighing in air beforehand.
