Test conditions
The Small Volume Sample Dispersion Unit is an accessory for the Mastersizer X,
S, Micro and Microplus. It stirs and pumps small volumes of a sample through
the test cell. It is activated by a control box which displays and adjusts the speed.
This is connected to the Mastersizer Digital I\O so that the speed can be
automatically recorded by the test software (Mastersizer X/S only). During the
emission tests the equipment was set to the median stirrer speed. During the
susceptibility tests the equipment was set to a stirrer speed such that an observer
was able to note significant changes in the rate of rotation of the stirrer. This item
was marked so as to facilitate this. The susceptibility pass/fail criteria was that the
stirrer did not significantly change its speed of rotation and the controller
correctly displayed and reported that speed.
