| NTR classified preservative-treated laminated wood d4 | 250 | 2024-12-02 | DownloadPreview |
In connection with the implementation of the European standards for preservative-treated wood (EN 351) and wood preservatives (EN 599), INSTA 140 was withdrawn in 1997. With the attempt to maintain the well-established wood preservation classes, presently called wood protection classes, the NWPC decided to prepare a Nordic application document of EN 351, NWPC Document No 1, Part 1. Thus, the first edition of NWPC Document No 1, Part 1, came into force in 1998.
