Specific Gravity Balance For Testing Lab Workshop.
Specific Gravity Balance -
The Specific Gravity Balance
provides a simple and quick mean to read directly the specific gravity
of rubber and other elastomers, thus reducing labour and eliminating
calculations. The time taken to find out the specific gravity of a
sample is only about half a minute.
The balance consists
of an anodised scale with specific gravity (SG) printed on it standing
vertically on a heavy base plate. A balancing arm is provided at the
centre point of the scale. The arm is supported on two jewel bearings to
minimise friction.
Two stainless steel pins are
suspended from one end of the arm. One of the pins is attached through a
short length of yarn and the other through a long length of yarn. The
second pin is kept immersed in water inside a tall transparent jar kept
on the base.
A pointer is attached at the other end of the
balancing arm that indicates the specific gravity of sample under test. A
sliding weight is also provided for initial balancing of the samples of
different weights. A levelling screw is provided for initial levelling
of the base plate.
A sample of any shape can be used for
determination of specific gravity. Its weight shall, however, lie
between 5 and 15 g. The sample used shall not be soluble in water or be
affected by it in any way. If the sample has a cellular structure, the
cells shall be of closed type so that the absorption of water is kept at
minimum.
