Standard CAN/BNQ 2501-092
Soils - Determination of Liquid Limit by a Fall Cone Penetrometer and Determination of Plastic Limit

CAN/BNQ 2501-092 is a national standard that specifies the test method used to determine the liquid limit using a fall cone penetrometers and to determine the plastic limit of soils, from which the plasticity index is derived. The standard sets out requirements regarding five test method elements:

  • apparatus (sieve, rubber paddle, mortar, pestle, bowl, spatula, penetrometer, cone, stainless steel container, running surface and other apparatus);
  • preparing the sample (preparing cohesive soils visibly free of any particles larger than 400 µm, cohesive soils containing particles larger than 400 µm and cohesionless soils);
  • procedures (determining the liquid limit (multipoint and one-point methods) and determining the plastic limit);
  • calculating and expressing the results (determining the liquid limit (multipoint and one-point methods) and determining the plastic limit and plasticity index);
  • test report.
