RG/WP 18-20639

K Yamamoto, I Momohara

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.
