This document consists of two parts, Part 1 determines the natural durability of solid wood against wood destroying basidiomycetes fungi and Part 2 against soft rotting micro-fungi. According to the CEN/CENELEC Internal Regul

DD CEN/TS 15083-2:20054 Introduction This CEN Technical Specification describes a laboratory method of test which gives a basis for the assessment of the natural durability of a sample of timber a
23、gainst micro-fungi (ascomycetes and fungi imperfecti) which cause soft rot of wood in service. The infection source is the natural micro-flora of the soil substrate which can also contain other micro-organisms, such as bacteria, and other fungi such as moulds and basidiomycetes. These other organism
24、s can influence the development of soft rot attack in the test specimens. The natural durability of a species of timber can vary depending on the conditions of growth such as climate and soil type. For this reason, the durability established using the method described in this CEN Technical Specifica
