Efficacy testing of wood preservatives

Efficacy against wood destoying fungi

  • Determination of toxic values against basidiomycetes and soft rotting fungi after full impregnation (EN 113, ENV 809)
  • Determination of preventive efficacy against basidiomycetes after surface treatment (ENV 839)
  • Determination of efficacy depth against basidiomycetes by planing off (DIBt test guidelines)
  • Determination of the durability of wood-based panels against basidiomycetes (ENV 12038)
  • Determination of the efficacy of preservatives against overgrowing by Serpula lacrymans from masonry to wood (ENV 12404)
  • Long- term efficacy in ground contact according to BAM- Schwammkeller method
  • Field trials of all types with and without ground contact:
    • Double-layer test
    • Lap-loint test (CEN TS 12037)
    • L-joint test (EN 330)
    • Stake test (EN 252)
    • Preservatives against sapstain on freshly cut wood (CEN/TS 15082)
    • Natural preconditioning (CEN/TS 15397)
  • Determination of the durability of modified wood / wood plastic composites against basidiomycetes
  • Efficacy testing of film-preservatives against fungi in coating materials

Efficacy against wood-staining fungi and algae

  • Determination of the protective effectiveness of a treatment of wood in service against blue stain according to EN 152
  • Determination of the effectiveness of treatments against blue stain, mould and algae by lab and field tests

Efficacy against insects

  • Determination of toxic values against larvae of Hylotrupes bajulus, Anobium puncatum and Lyctus brunneus after full cell impregnation (EN 47, EN 49-2, EN 20-2)
  • Determination of preventive efficacy against larvae of Hylotrupes bajulus, Anobium puncatum and Lyctus brunneus after surface treatment (EN 46, EN 49-2, EN 20-1)
  • Determination of efficacy depth against insects by planing off (DIBt guidelines)
  • Determination of curative efficacy against Hylotrupes bajulus and Anobium punctatum (ENV 1390, EN 370)
  • Determination of the efficacy of preservatives against termites (Reticulitermes santonensis, Mastotermes darwiniensis, EN 117, EN 118)

Fast testing

For fast testing of potential actives and formulations regarding fungicidal or insecticidal efficacy we offer numerous screenings. They are permanently beeing improved and they excel by speed, reliability and reproducibility of results.

Examples:
  • Hylotrupes-screening (3 weeks)
  • Termite screening (4 weeks)
  • Basidiomycete-screenings (4 resp. 8 weeks)
  • Fungicide-screening (gas-liquid or solid phase: 1-2 weeks)

Consulting

We advise developers of new preservative formulations or procedures about approval requirements for wood preservatives as well as to their prospects for an approval and accompany registration/authorization procedures.
