The Canadian Grain Commission, the regulatory department within the Canadian government which regulates grain trade in Canada, has a testing procedure for buckwheat in their grain standards. This testing procedure uses the Carter Day Dockage tester and has specific sieves and settings for the separation of dockage from Buckwheat. This test method would be used for the evaluation of a shipment of buckwheat for the determination of grade or quality. There are other small capacity cleaners for the general cleaning of a large bulk of buckwheat. These cleaners would separate out the good kernels of buckwheat from the chaff and debris.

This directive establishes procedures under the Agricultural Marketing Act of 1946, as amended, for the factor analysis of buckwheat.

荞麦分级定等的方法的主要文献为：美国农业部FGIS, GIPSA的Directive ：Inspection of Buckwheat,美国 ARTICLE 74-06 COMMODITY STANDARDS: 74-06-02 Buckwheat和加拿大谷物委员会Official Grain Grading Guide： Buckwheat. 一、美国农业部FGIS, GIPSA荞麦标准包含的主要检测内容 1、 气味Ordor (P2, Directive ：Inspection of Buckwheat) 2、 水分Moisture (P4, 同上) 仪器：美国帝强GAC2100高精度水分容重仪，配荞麦检测曲线 3、Garlicky 荞麦 (P4, 同上) 仪器：粮食感官检验图谱VRI，荞麦部分 4、杂质率 (P5, 同上) 仪器：美国卡特除杂清理机，配荞麦检测筛网。 4、容重 (P5, 同上) 仪器：美国Seedburo粮食容重仪，标配。 5、麦角病荞麦 Ergoty Buckwheat (P7, 同上) 仪器：粮食感官检验图谱VRI，荞麦部分 6、黑穗病荞麦 Smutty Buckwheat (P7, 同上) 7、颗粒大小分布 （P2，CH 74-06-02 Buckwheat） 仪器：法定燕麦分级筛 加谷委2010年版荞麦检验规程，与美国标准高度相似。 有一定不同的是：加拿大首先用卡特除杂机荞麦分为大颗粒荞麦和小颗粒荞麦。 大小颗粒两类荞麦的杂质率检测，均使用卡特除杂机，但对应的筛网有所区别。
