In This Series
Non-destructive testing (NDT) may be defined as 'any means of determining the properties of a material, without causing significant changes to those properties'. This definition permits some degree of damage, providing the performance of the material, in this case timber, is not affected.
This Wood Information Sheet is an introduction to non-destructive testing of timber in buildings and other structures for architects, engineers, surveyors and building inspectors. The various NDT techniques are discussed, together with their capabilities and limitations.
