4.4.14.2 Classes 6. Prepare an isopropyl alcohol wash solution by transferring 5 g of the
specimen to a 250 mL Erlenmeyer flask and add 150 mL of isopropyl alcohol. Place the flask
on a shaking machine and shake for 1 hour at a temperature of 25°± 5°C. Decant and filter the
solution through Whatman No. 41 filter paper. Retain the filtrate for use as a wash solution.
Weigh to the nearest 0.01 g approximately 10 g of the specimen and place on a 3 inch diameter
No. 325 sieve conforming to ASTM E 11. Wash the material with a steady gentle steam of the
isopropyl alcohol wash solution at a temperature of 25°± 5°C from a wash bottle, breaking any
lumps formed by touching them with a glass rod. Continue washing until no more specimen
passes through the sieve, catching the washings in a beaker. During the washing shake the sieve
gently. Occasionally tap the bottom of the screen with a glass rod. Dry the sieve on a steam bath
until the odor of alcohol can no longer be detected and then dry in an oven at 100° to 105°C for
15 minutes. Cool in a desiccator, weigh the residue, and calculate the percent passing through.
