Notes

This species is listed in the NF EN 350 standard. This species naturally covers the use class 5 ( wood permanently or regularly submerged in salt water, sea water or brackish water) due to its high specific gravity and its hardness. According to the European standard NF EN 335 of May 2013, performance length might be modified by conditions in which it is used .

Preservation Treatment

Against dry wood borer attacks. This wood does not require any preservation treatment.
In case of temporary humidification This wood does not require any preservation treatment.
In case of permanent humidification This wood does not require any preservation treatment.

Sawing and Machining

Blunting effect Fairly high
Tooth for sawing Stellite tipped
Machining tools Tungsten carbide
Suitability for peeling Not recommended or without interest
Suitability for slicing Not recommended or without interest

Drying

Drying rate Slow
Risk of distortion Slight risk
Risk of case hardening No known specific risk
Risk of checking Slight risk
Risk of collapse No known specific risk
Suggested drying schedule Schedule # 7

Assembling

Nailing/ Screwing Good but pre – boring necessary.
Notes Very high specific gravity: important that gluing be performed in compliance with the code of practice and instructions for the glue used.

Commercial Grading

Sawn timber appearance grading

According to NHLA grading rules (2015) Possible grading: FAS, Select, Common 1, Common 2, Common 3

Fire Safety

Conventional French grading Thickness > 14 mm: M3 (moderately inflammable)
Thickness < 14 mm: M4 (easily inflammable)
Euroclass grading D-s2, d0
Default grading for solid wood that meets requirements of European standard NF EN 14081-1 (April 2016): structural graded timber in vertical uses and ceilings with minimal mean density of 0.35 and minimal thickness of 22 mm.

Visual structure grading

According to European standard EN 1912 (2012) and associated national standards, strengths classes D50 and D70 can be provided by visual grading.

Main End uses

  • Turned goods
  • Heavy carpentary
  • Ship building (planking and deck)
  • Tool handles( resilient woods)
  • Industrial or heavy flooring
  • Decking
  • Bridges (parts in contact with water or ground )
  • Poles

Notes

Though infrequently used in France, Greenheart is one of the most suitable species for end used submerged in salt water, sea water or brackish water. Species is resistant to acids. Greenheart is also used for billiard cues
