scope:

This Technical Report specifies the minimum performance requirements for hot air treatment intended for application against specific classes of wood attacking organism. It specifies the minimum performance criteria to be achieved by hot air treatment.

NOTE Until now sufficient practical experience and results of scientific tests are available only for heat treatments using hot air as a medium to increase the temperature inside building components up to a threshold lethal to wood destroying organisms. Therefore, this document is restricted to hot air treatments although other measures like, for example, radio waves or electric blankets may be useful means for limited and special applications.

This document is applicable only to hot air treatment, in so far as it is intended to cure attack by wood destroying beetles and the dry rot fungus (Serpula lacrymans).

This Technical Report is not applicable to eradicate an attack by termites or by fungi other than the dry rot fungus (Serpula lacrymans).

Hot air treatment as described in this document does not provide subsequent preventive protection against attack by wood-destroying organisms.

This document does not define the equipment, techniques or precise operation procedures required to achieve the parameters given in Clauses 4 and 5 for any set of practical circumstances. Specifications for particular practical circumstances have to be developed on a case by case basis by expert advisers/consultants.
