Testing Method

Testing Method

1. Density

-Use the Archimedes’ principle

-Model:DH300

  1. Bulk Density

Please check density ( use balance which is 2 digit as significant figure) by following method This density is
value on the average from 3 times analysis

Required test apparatus
Bulk Density Tester , balance ( 4 digit), Funnel. 1L Mess cylinder

Test method
① put 1ℓ mess-cylinder on the balance and tare weight of mess-cylinder and make “0” = the balance
② put funnel on the 1ℓ mess-cylinder and feed bead via funnel until mess-cylinder to be 1L..
③ And check weight of mess-cylinder.

※ cf) use proper funnel and fill bead into mess-cylinder properly to avoid mistake ( low density).
