Assemble the apparatus as picture below, put the measuring cup in the axis of the funnel orifice.
Adjust the stand screws and make the bubble in center to level the instrument.
Put the height control ...
-
Pour a 115 ± 5 cm³ sample into the funnel.
Open the bottom of the funnel quickly and allow the material to flow freely into the cup.
NOTE 1: If caking occurs in the funnel, the material may be loos ...
-
Measure the apparent density of the material in accordance with the applicable test method as defined in No.2 procedure
Measure the density of the molded or formed plastic material in accordance wit ...
-
Calculate the bulk factor of the plastic material as follows:
Bulk factor = D2/D1
where:
D2 = average density of the molded or formed specimen,
D1 = average apparent density of the plastic materia ...
-
Report the following information:
Average apparent density of the plastic material and the method employed
Average density of the molded or formed specimen
Bulk factors calculated from them.
NOTE 7: ...
-
The apparatus shall consist of the funnel described in Test Method A, mounted as shown, and either a stopwatch or an electric timer of comparable accuracy.
NOTE 9: Pourability may be measured with the ...
-
Take a sample of the plastic material weighing, in grams, 100 times its specific gravity (or density) after molding or forming.
Work this sample on a paper until there is no tendency for the material ...
-
Report the time in seconds required for the funnel to discharge, to the nearest 0.2 s; or if so found, that the material will not run through the funnel.

-
Place the measuring cylinder on a piece of paper. Loosely drop 60 ± 0.2 g of the material to be tested into the measuring cylinder from a height approximately that of the cylinder, taking care to los ...
-
2. Fill the weight plunger with lead shot to obtain a total weight of 2300 ± 20 g (5.07 ± 0.04 lb), including the plunger. Lower this weight gradually into the measuring cylinder until it is entirely ...
-
3. 1 Calculate the apparent density of the material before and after application of the load as follows, making separate calculations for both H1, and H2:
V = H × A
Apparent density = W/V
where:
V = v ...
-
4. Report each value of the apparent density and of the average density, both before and after loading.
...

The test report shall include the following particulars:
a) the reference of the method used;
b) the results and the method of expression used;
c) any unsual features noted during the determination;
d ...

♦ The untamped density of aluminium oxide is given by the formula m2-m0/m1-m0
where
—m0 is the mass, in grams of the empty cylindrical container
—m1 is the mass, in grams of the cylindrical container ...
-
♦ Set the cylindrical container on a flat base.
♦ Adjust the funnel so that its axis coincides approximately with that of the cylinder, with the tip of the funnel at a height of 10 cm above the cylind ...

1.1 Pour into the closed funnel a quantity of the fertilizer greater than that needed to fill the measuring cylinder.
1.2 Fully open the slide of the funnel so that the contents discharge into the mea ...
-
2. If the fertilizer does not flow freely, keep the outlet clear by inserting a rod of 3 mm to 4 mm diameter into the opening.
...
-
3. When the cylinder overflows, close the slide of the funnel and scrape away the surplus fertilizer using the spatula or other suitable tool. Avoid vibration of the filled measuring cylinder.
