Tolerance and rejection limits

  • Bark
    On principle, wood chip delivery should be free from bark. As small quantities of bark are unavoidable due to technical reasons, a share of less than 3% is tolerated. 3% and more will cause deductions. The triple amount is deducted. Example: 3% pure bark means deduction of 9% wood chips (4% bark - 12% wood chips, etc.). Wood chips with more than 6% bark cannot be processed. Delivery is rejected.
  • Fines
    Tolerance limit 4.5%. Higher percentages will be deducted accordingly. 5.5% fines means a deduction of 1%. For the determination of fines content a representative sample is taken. The sample is then graded in a wood chip analyzer. Fines percentages are established on a monthly basis. The average forms the basis for the quality assessment of the complete delivery of the respective month. (Instruction No. FPHDA001)
  • Impurities
    Impurities are plastic, metal, stone, coal, etc. (foreign matter of any kind). Due to technical reasons contaminated chipped wood cannot be processed. Delivery is rejected. Additon of wood shavings, saw dust, leavings of deer fences, chip wool, dirt and snow is not permissible.
