Changes to Standards & Regulations
Checklist: Changes to Standards and Regulations
Note on key structural standard (BS) EN 13986:2004+A1:2015
This is the overall harmonised/designated standard for the use of plywood, OSB and LVL in construction, defining their performance characteristic and test methods. Compliance indicates that a specific product is ‘fit for purpose’ to be used for a particular, intended end use. Linked to the CPR, it will be further reviewed as part of revisions to the regulation.
