TEST PROCEDURE AATM 107A-c Edition: November 4, 2009

Previous Edition: October 17, 2006

ASH DESCRIPTION OF METHOD A weighed amount of test material is ignited in a porcelain crucible and then completely oxidized to constant weight in a 700-900C muffle furnace. The weighed residue is reported as percent ash. The method for sulfated ash when specified is given in Method 107 B. APPARATUS 1. Crucibles - porcelain - 40 ml. 2. Hot Plate. 3. Muffle Furnace - 700-900C ( 24). 4. Desiccator containing dried desiccant. 5. Analytical balance capable of weighing to the

nearest 0.1 mg. PROCEDURE 1. Heat a clean crucible for at least 30 minutes in

a muffle furnace at 700-900C. 2. Place the crucible in desiccator and allow it to

come to room temperature. 3. Weigh the crucible and accurately record the

weight to the nearest mg. 4. Into the crucible weigh 10-15 g of test

material. Record the exact weight to nearest mg. Obtain the weight of sample by difference.

5. Heat the sample on a hot plate until it can be lighted using a match or glowing splint or until it spontaneously ignites on top of the muffle furnace door. (If the sample contains any amount of water, initially remove the water by gently boiling on a hot plate until the sample can be heated and ignited.)

6. Place the burning sample on the hot plate until

the sample is completely ashen. 7. Place the crucible in the furnace with the door

partly open until most of the black carbon residue has burned off. Close the door and heat the crucible at 700-900C to oxidize the remaining carbon.

8. Remove the crucible from the furnace and

place it in a desiccator and allow it to come to room temperature.

9. Weigh the crucible accurately. Calculate %

Ash (see below).

10. Reheat the crucible in the furnace for 30 minutes at 700-900C, then allow to cool in a desiccator and reweigh. If necessary, repeat procedure until a constant ( 1 mg) weight is reached.

11. Continue above step until a constant (+ 1 mg)

weight is reached.

TEST PROCEDURE AATM 107 A-C ASH

Page 2 of 2 ADDITIONAL NOTES: The following special conditions should be followed when determining percent ash in Glucate SS and Glucate DO emulsifiers to ensure repeatable, accurate results.

1. Use a high muffle furnace temperature, 850 -

900C 2. Use a sample weight of 10 - 10.5 g. 3. Extend the residence time of the sample in

muffle furnace to 4-5 hours. Reheat minimum of 2-3 hours. Continue the reheating/cooling cycle until a constant weight is achieved. Total test time may exceed 8 hours.

CALCULATIONS % Ash = Weight of Residue (g) X 100 Weight of Sample (g)
