The Procedure for Laboratory Testing of Oil Grit Separators provides performance testing for the following performance measures based on a standard sediment particle size distribution:
The [https://sustainabletechnologies.ca/app/uploads/2023/06/SETV-OGS-PAS-2023-06-01-English-1.pdf Canadian Procedure for Laboratory Testing of OGS] provides performance testing for the following performance measures based on a standard sediment particle size distribution with a median particle size of 75 microns:
# '''Sediment removal performance''': Mass balance testing at seven surface loading rates to determine the capacity of MTDs to retain solids
# '''Sediment removal performance''': Mass balance testing at a minimum of seven surface loading rates to determine the capacity of MTDs to retain suspended solids
# '''Sediment scour and re-suspension test''': Sediment is pre-loaded into the unit and effluent concentrations are measure at five surface loading rates to determine how well the units retain captured sediment.
# '''Sediment scour and re-suspension test''': Sediment is pre-loaded into the unit and effluent concentrations are measured at a minimum of five surface loading rates to determine how well the units retain captured sediment.
# '''Light liquid capture and retention test''': An optional test in which beads with a density similar to motor oil are pre-loaded into the unit and the number of beads in the effluent are measured to assess the capacity of the unit to trap and retain light liquids.
# '''Light liquid capture and retention test''': An optional test in which beads with a density similar to motor oil are pre-loaded into the unit and the number of beads in the effluent during pre-loading and testing are measured to assess the capacity of the unit to trap and retain light liquids.
There are currently eight OGS vendors with ISO 14034 verifications (as shown in the [[Oil and Grit Separator#Testing and Verification|table]] above). A summary of OGS MTD test results from the verification statements is provided [https://etvcanada.ca/home/verify-your-technology/current-verified-technologies/ here]
