Observing the number of particles greater than 10 microns and equal to not less than 25 microns, measured to calculate the number per ml of the test solution or bottle containing insoluble particles.
The number of particles greater than or equal to 10 microns and 25 microns or more was observed and the number of insoluble particles per milliliter or bottle of the test fluid measured was calculated.
Observe the number of particles greater than or equal to 10 microns and greater than or equal to 25 microns, and calculate the number of insoluble particles in each ml or bottle of the tested test solution.<br>
