Test weight

Grain test weights in Canada are measured using a Canadian Regulation Cox Funnel, a .5 liter cup, strike off tool and scale. The procedure to attain this measurement and the conversion tables from grams per half liter to kilograms per hectoliter is available on the CGC web site. The Cox Funnel used by the USDA is built to different specifications than the funnel used by the CGC. Both the American and Canadian Cox Funnel will fit the .5 liter cup so be sure to use the Canadian funnel to achieve the proper test weight.

When purchasing your test weight equipment to be used in Canada specify a Canadian Regulation funnel. Some of the automatic moisture testers will display a test weight as well as moisture. In Canada these test weights are considered approximate only. The official test weight procedure includes the .5 liter cup, Cox funnel, strike-off tool and scale.

When moisture testing corn greater than 20% a test weight adjustment chart is used. The results obtained from a wet corn test weight, using a Canadian Cox funnel and .5 liter cup, and the moisture test obtained from a digital moisture tester will give the final moisture result. These charts are available on the CGC web site.

Cox Funnel

Cox Funnel

The Cox Funnel provides for uniform “fall” of grain into a density cup at the proper 3.81cm height for standard bulk density. Funnel is placed on the lip of the cup and filled. Slide gate lets grain fill and overflow the cup for strike-off. Made of heavy non-corrosive metal.

ABS Regulation Cox Funnel

Placed on top of our .5 L measure. Standardizes the fill of the .5 L measure each and every time. Promotes more accurate and consistent test weight determination. Designed to meet government agency specifications with a 3.81cm drop from an opening of 4.41cm.

 

1/2 Litre Cups

0.5 L Measure

0.5 L Measure Used for test weight determination. Used to determine grams/0.5 L which is then converted into lbs./Bushel or kg./hL using conversion charts. Meets government agency specifications.

The density cups are available for use on the Filling Hopper and Stand, and other filling devices are: Quart Cup (meets the specifications of the USDA-FGIS (GIPSA) for official inspection), Pint Cup, Liter Cup, and Half Liter Cup.

ABS Plastic 0.5 L Measure

ABS Plastic 0.5 L Measure used for test weight determination. Used to determine grams/0.5 L which is then converted into lbs./Bushel or kg./hL using conversion charts. Meets government agency specifications.
