Provides a table of timber species and their general properties which can be used for the design of timber structures. Extensive explanatory clauses to the table are also provided.

This Standard sets out a table of species and their general properties which can be used for the design of timber structures.NOTES:1 It is emphasized that structural timber exhibits considerable natural variability and consequently the information given herein might be inadequate when precise and specific data are required.2 The inclusion of a species in this Part does not necessarily indicate that it is readily available.
