Scope of the Interlaboratory Proficiency Testing

The scope of this proficiency testing is the evaluation of the performance of laboratories for the determination of the physical chemical parameters in waste water.

Parameters

  • Ammonia Nitrogen
    (1 - 20 mg/L N)
  • Biochemical Oxygen Demand (BOD5)
    (20 - 200 mg/L O2)
  • Chloride
    (100 - 1000 mg/L)
  • Chemical Oxygen Demand
    (COD)
    (25 - 250 mg/L O2)
  • Conductivity (20 oC)
    (500 - 2000 microS/cm)
  • Fluoride
    (1 - 20 mg/L)
  • Nitrate Nitrogen
    (2 - 25 mg/L N)
  • Nitrite Nitrogen
    (0.4 - 4.0 mg/L N)
  • pH (20 oC)
    (6.5 - 9.5 U)
  • Sulphate
    (100 - 1000 mg/L SO4)
  • Total dissolved solid
    (150 - 1500 mg/L)
  • Total Kjeldahl Nitrogen
    (1 - 20 mg/L N)
  • Total Organic Carbon (TOC)
    (10 - 100 mg/L C)
  • Total phosphorus
    (0.5 - 10 mg/L P)
  • Total Nitrogen(**)
    (1 - 50 mg/L N)
  • Total solids
    (150 - 1500 mg/L)
  • Total suspended solids (TSS)
    (20 - 100 mg/L)

**: Determination of the Total Nitrogen (organic and inorganic) . Reference methods: ISO11905-1, UNI EN 12260 or equivalent methods.

Proficiency test item:

  • 1 x 1000 mL of the test material ready to use for the determination of all parameters except BOD5, COD, TOC and TSS.
  • 1 x 1000 mL of the test material to be prepared from a natural water matrix and a vial of the spiking solution for the determination of BOD5, COD and TOC.
  • 1 x 500 mL of the test material material ready to use for the determination of Total dissolved solid, Total solids and Total suspended solids.
