本欧洲标准规定了用于型式试验的参考方法，如果有争议，则用于确定粗细和细骨料的流动系数。为了其他目的，特别是工厂生产控制，可以使用其他方法，条件是与参考方法建立适当的工作关系。高级测试方法的例子可以在参考书目中找到。 本欧洲标准适用于尺寸在4 mm和20 mm之间的粗骨料，以及尺寸高达2mm的细骨料。 注1:对于4 mm至20 mm之间的粗骨料，流量系数与骨料的破碎或破碎表面的百分比相关，因此可与EN 933-5中规定的方法相结合使用。形状和表面纹理特征也影响结果。 注2:本测试的经验一般限于天然聚集体

This European Standard specifies the reference method used for type testing, and in case of dispute, for determining the flow coefficient of coarse and fine aggregates. For other purposes, in particular factory production control, other methods may be used provided that an appropriate working relationship with the reference method has been established. Examples of advanced test methods can be found in the Bibliography. This European Standard applies to coarse aggregate of sizes between 4 mm and 20 mm and to fine aggregate of size up to 2 mm. NOTE 1 For coarse aggregates between 4 mm and 20 mm, the flow coefficient is linked with the percentage of crushed or broken surfaces of an aggregate and can therefore be used in association with the method specified in EN 933-5. Shape and surface texture characteristics also influence the result. NOTE 2 Experience of this test has been generally limited to natural aggregates.
