We are leading in civil engineering trials
Classification test
Classification testing in accordance with NEN-EN 933-11 is carried out to determine which product a material falls under or whether contaminants are present. The sample is first sorted by hand. Parts between 4 and 63 mm are then visually determined in which category they fall.
