What is BS EN 84 about?
BS EN 84 discusses the leaching procedures for wood and wood-based products. EN 84 specifies a method for leaching, applicable to test specimens of wood or wood-based products which are subsequently subjected to biological tests.
Note 1: BS EN 84 is applicable to:
- The pre-conditioning of test specimens prior to their being subjected to a biological test
- Assessment of loss of effectiveness by comparing the performance in a biological test of treated test specimens subjected to this procedure with others that have not undergone any leaching procedure
Note 2: The method used for pre-conditioning of untreated wood, modified wood, and wood-based panel products, whether they received preservative treatment or not.
Who is BS EN 84 for?
BS EN 84 on leaching procedure for accelerated ageing of treated wood is useful for:
- Wood and wood products manufacturers
- Quality control laboratories
Why should you use BS EN 84?
Wood is a renewable material, with many end-uses from furniture, craft, and art to building purposes.
BS EN 84 specifies a method for leaching that helps you extend the life of wood which makes the wood more durable and lasts longer.
BS EN 84 provides the leaching procedure of wood-based products which is a commercially applied preservative that is widely used to protect the wood from attack by decay fungi and insects, which helps you to ensure the durability of wood and wood-based products.
BS EN 84 is intended to ensure the durability of wood and wood-based products by using a leaching procedure that helps you to protect wood and wood products from decay fungi and insects.
BS EN 84 provides a leaching procedure, that protects woods that are used in manufacturing wood-based products and used in building purposes.
BS EN 84 specifies state the period of time between the completion of the leaching procedure and the start of the biological test.
What is changed since the last update?
BS EN 84:2020 supersedes BS EN 84:1997, which is withdrawn.
BS EN 84:2020 includes some technical changes with respect to BS EN 84:1997. These include:
- Change of title
- Inclusion of untreated wood, modified wood and wood-based panel products in the scope
- Terms and definitions, and renumbering of subsequent clauses and cross-references
- Inclusion of a statement regarding the maximum period of time permitted between the completion of the leaching procedure and the start of the biological test
- Inclusion of a requirement that this period of time be stated in the biological test report
