The only approved method to determine test weight of Canadian grain is with a
Canadian Regulation Cox funnel
0.5 litre cup
striker tool, and
scale

Some moisture meters and protein analyzers display a test weight value. In Canada, these test weights are considered approximate only.

Refer to the Canadian Grain Commission’s website for the proper procedure for determining test weight of Canadian grain.

The CGC provides test weight conversion charts for Canadian grains. These charts are updated periodically, so check the website to ensure you are using the latest version.

* Important note about Canadian and USA Cox funnels*
Please note, the Cox funnel used for test weight determination in the USA is built to different specifications than the funnel used in Canada. It can be difficult to tell the difference because both the USA and Canadian Cox funnels fit on a 0.5 litre cup. However, due to the slight difference in design, there is variation in how grain falls and compacts in the cup that affects the grain volume.
