What is PD CEN/TR 15003 – Criteria for hot air processes for curative uses against wood destroying organisms about?
PD CEN/TR 15003 discusses the durability of wood and wood-based products. The main aim of the PD CEN/TR 15003 is to ensure the efficiency of the hot air processes for curative uses against wood destroying organisms.
PD CEN/TR 15003 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. PD CEN/TR 15003 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).
Note 1: PD CEN/TR 15003 is not applicable to eradicate an attack by termites or by fungi other than the dry rot fungus (Serpula lacrymans).
Note 2: Hot air treatment as described in PD CEN/TR 15003 does not provide subsequent preventive protection against attack by wood-destroying organisms.
Note 3: PD CEN/TR 15003 does not define the equipment, techniques or precise operation procedures required to achieve the parameters 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.

Why should you use PD CEN/TR 15003 - Criteria for hot air processes for curative uses against wood destroying organisms?
Hot air processes helps in the eradication of infested timber and/or masonry in order to kill the wood-destroying insects and the dry rot fungus. The application of heat to a particular temperature for a particular period of time under particular environment conditions, can successfully kill wood attacking organisms. This includes the various stages of beetles inside wood, that is eggs, larvae, pupae and imagos, and the hyphae of the dry rot fungus (Serpula lacrymans) inside wood or masonry.
PD CEN/TR 15003 helps in expert diagnosis that should take into account all regional, practical, environmental, economical, safety and any other factors which may be relevant to the prescriptive decisions to be taken. PD CEN/TR 15003 helps in proper hot air treatment that should not influence the mechanical properties of the timber involved. PD CEN/TR 15003 provides precautions that shall be taken during the hot air treatment to avoid harmful damages on joinery timbers caused as a consequence of unforeseen drying induced by the hot air process, also it is necessary to monitor and control carefully the relative humidity of the heated air. PD CEN/TR 15003 provides requirements for monitoring and process validation. This will make sure the hot air treatment can access the areas that are difficult to be heated and ensure the efficacy of a hot air treatment.
