Heat Treatment - the process whereby wood is heated in accordance with a time-temperature schedule that achieves a minimum temperature of 56 degrees Celsius for a minimum duration of 30 continuous minutes throughout the entire profile of the wood (including at its core).
ISPM15 (International Standards For Phytosanitary Measures No. 15) - is an International Phytosanitary Measure developed by the International Plant Protection Convention (IPPC) that directly addresses the need to treat wood materials of a thickness greater than 6mm, used to ship products between countries. Its main purpose is to prevent the international transport and spread of disease and insects that could negatively affect plants or ecosystems.
Kiln-drying - a process where the moisture content of the wood is reduced to below 20% expressed as a percentage of dry matter, at the time of treatment, achieved through an appropriate time/temperature schedule.
Official Statement - means, in relation to any testing or other procedure required to be carried out in respect of any controlled material, a statement made by or under the supervision of the Plant Protection Organisation in the country where the testing or procedure was carried out. In the case of material originating in a third country, the statement will be deemed to have been made by virtue of the presence of a phytosanitary certificate. In the case of material originating in the EU, the statement will be deemed to have been made by virtue of the presence of a plant passport issued by a registered producer following any appropriate inspection of the place of production and the immediate vicinity by the Plant Protection Organisation concerned.
Phytosanitary Certificate - statement of plant health status made by means of a document set out in an internationally prescribed format, issued by a Plant Protection Organisation and specifically addressed to an official Plant Protection Organisation in the importing country. It confirms the identity of the material; confirms that it has been inspected and that it is considered to be free from quarantine pests, and that it otherwise meets the import regulations of the declared country of destination. It must be completed in English.
Plant Passport - a label or a document, or a combination thereof, containing required information, issued by any person listed on a register kept by the Forestry Commission or any other Plant Protection Organisation of the European Union. ‘Plant passports’, ‘replacement plant passports’ and ‘plant passported’ shall be construed accordingly.
Protected Zone - a part of the EU where a particular harmful organism is officially known not to be present, or is present but is subject to official plant health control measures. As a result, a higher plant health status prevails requiring special measures to be taken before host material is consigned into, or moved through it.
Registered trader - a grower, owner, agent, sawmiller, timber merchant, timber user, or wood processor dealing with any material subject to plant health controls who has signed an undertaking to comply with certain obligations and to whom a registration number has been assigned by the Forestry Commission or another official Plant Protection Organisation.
Regulated (controlled) material - wood from tree species which are known to host harmful pests or diseases are subject to special requirements or, where the risk is too great and no effective treatment is known, prohibition.
