Moisture Test Procedure for Standard Size Speedy
A standard size speedy is shown in the photograph to the left. The moisture test
procedure is simple to follow and takes a just few minutes for most materials.
However, to ensure accurate and consistent results the procedure should be
followed precisely. To test your sample, refer to the photographs below and
complete the following steps:

1. Clean the Speedy vessel: Prior to using the Speedy tester, ensure that the inside of the Speedy cap and vessel are empty
and clean. Use the bristle brush to remove any residues from previous tests.
2. Select and prepare the sample: Ensure that the sample to be weighed and placed in the Speedy is representative of the
material that is under investigation. Some materials, such as free-flowing powders and sands, need no preparation whereas
others may need to be ground prior to testing. See Table 4 on page 6 for further information.
3. Weigh the sample: Place the empty measuring beaker on the electronic scale and zero the scale (refer to the electronic
scale user instructions for further details). Add small amounts of material from the sample until the correct sample weight
is reached. The sample weight is determined by the size and measurement range of the Speedy that is being used, as listed
in Table 2 below.

4. Add the sample to the Speedy vessel: Pour the sample into the chamber of the Speedy vessel.
5. Add the reagent to the Speedy cap: Using the metal scoop, add a minimum of two full scoops of calcium carbide
reagent to the Speedy cap cavity.
6. Seal the Speedy: Hold the Speedy horizontally and position the cap as shown. Then swing the stirrup into position and
tighten the top screw to seal.
7. Mix the sample with the reagent: Hold the Speedy vertically with the pressure gauge facing the ground and shake
vigorously for 5 seconds. Rotate the Speedy through 180° so that the pressure gauge faces the sky, tap the sides of the
Speedy to ensure the sample falls into the cap cavity and prop or hold the Speedy in this position for 1-2 minutes.
8. Take the reading: Hold the Speedy horizontally and at eye level and take the moisture content reading directly from the
pressure gauge.
9. Release the pressure: Hold the Speedy vertically with the pressure gauge facing the ground. Locate the arrow on the
flange of the cap and point this away from yourself and other people in your vicinity. Unscrew the top screw slowly to
vent the gas that may have been generated within the Speedy.
10. Remove the sample and reagent: Tip the contents of the Speedy directly into a clean and dry open container and
dispose of in accordance with Section 13 of the Calcium Carbide Material Safety Data Sheet.
11. Clean the Speedy: Clean the Speedy vessel, cap and measuring beaker in preparation for the next moisture measurement.
