The environment and the timber preservation in the Benelux countries
1990 - IRG/WP 3580
The environment has become a major issue in all industries. To focus on the timber preservation industry an analysis is made of the production chain. Suggestions are made for diminishing or excluding emissions of agents of pollution. After a review of the legislation in Holland, some important statements are made on the production process, the products involved and the waste materials. Finally raw materials and energy requirements are discussed. All stages of the product chain should take place in professional business units and under controlled circumstances. The innovations in timber preservation shall be based on existing products, which are very well known, such as CCA and creosote. A controlled and accelerated fixation process should be executed systematically. The preservatives have to be examined on their fixation properties. The industry has to take the initiative for guarantee systems on quality and certification.

Implementation of a Quality Assurance System for thermally modified timber (TMT) by the Association of Central European TMT-Producers
2011 - IRG/WP 11-40558
Due to increasing market shares of thermally modified timber (TMT) in Europe, a working group of ten central European TMT manufacturers (TMT-WG) was founded in 2010 to cover public relations and marketing activities. Since the present level of product testing and property declaration was not satisfying, a “task group TMT-quality” was put into action in 2010 to develop a comprehensive quality assurance concept (QA). This QA was approved by the TMT-WG in 2011. Consequently an incorporated association for TMT quality (“Thermoholz-Qualität e.V.”) was founded in February 2011 as a legal entity, responsible for granting the certification of quality of TMT after inspection and proposition by an independent third party quality committee. The criteria of the QA as well as rules and conditions for granting are described in this paper.

Ensuring Quality of Treated Wood – Regulations, Certifications and Associative Background in the Field of Wood Protection in Europe
2017 - IRG/WP 17-20626
Beside legal requirements, buyers and end-users of wood preservatives and/or of treated wood and wood-based materials may require additional warranties regarding the quality and the performance of the products available on the market. These greatly enhance the confidence of end-users and the chance for a product of being marketed with a quality label. Additionally, quality control systems and trained and motivated personnel can contribute to better control and/or reduce the risks for environment and human health which are associated with the use of biocides. The means used across Europe to ensure the safety and quality of treated wood and wood-based products include regulations (mainly the Biocidal Products Regulation and the Construction Products Regulation), but also quality labels and certification of products, processes, application equipment and people (such are professional users). Certification schemes exist in many EU member states. This paper is an attempt to give an overview of the main legal instruments and appropriate measures which exist in Europe to demonstrate efficacy, address risks and ensure a sustainable use of biocidal products and treated wood-based products. They include regulations, certifications of products, processes and people, and communities of industries involved in the field of wood protection.

Certification system for treated wood and wood preservative in the relation to regulations in Japan
2018 - RG/WP 18-20639
Certification system about wood protection products in Japan is described to understand the interaction between regulations and certifying organizations. Major regulations are Building Standard Law, Chemical Substances Control Law, Poisonous Deleterious Substances Control Act, Japanese Industrial Standards, and Japanese Agricultural Standard (JAS). Treated wood products are certified with JAS mark according to JAS or with Approved Quality (AQ) mark by Japan Housing and Wood Technology Center. AQ guarantees the quality of newly developed products not specified in JAS that would supplement the JAS system in wood products. Certification process of treated wood products by JAS requires the data and onsite examinations of quality control, quality stability and licenced person of maker factory by the designated organization as a third party. Certification process for AQ consists of the evaluation of product quality according to performance criterion by registered testing organization, the onsite examination of quality control and quality stability in the factory, and complaint procedure. Wood preservatives are certified and registered by Japan Wood Protection Association and/or The Japan Termite Control Association. Certification process of wood preservatives/termiticides requires the examination of safety and efficacy data by the Wood Preservative and Others Investigation Bureau as a third party organization.
