本文件规定了一种测定木材对在麦芽提取物琼脂培养基上培养的破坏木材的担子菌的自然耐久性的试验方法。该方法适用于所有树种。 此外，该方法可用于改性木材的测试。本文件中描述的试验方法可适用于特定木材种类、商用锯材、木质材料、经防腐剂处理的木材和改性木材，包括热改性和化学改性木材。 然而，本文件并不旨在确定用于防止腐朽的木材防腐剂的有效性。 注1:EN 113-1的范围是确定用于防止腐朽的木材防腐剂的功效。然而，除此之外，在某些情况下，还可以使用本文所述的方法测试处理过的木材。 注2:该方法可与老化程序结合使用，例如EN 73或EN 84。 附录A（资料性附录）包含取样指南。 附录B（规范性附录）包含一些灭菌方法。 附录C（资料性附录）包含有关培养容器的信息。 附录D（资料性附录）包含试验报告的示例。 附录E（资料性附录）包含试验真菌的信息。 附录F（资料性附录）载有对结果的评估。

This document specifies a method of test for determining the natural durability of a timber against wood-destroying basidiomycetes cultured on a malt extract agar medium. The method is applicable to all timber species. Furthermore this method can be used to test modified wood. The test method described in this document can be applied to specific wood species, commercial supplies of sawn timber, wood-based materials, wood treated with preservatives and modified wood, both thermally and chemically modified wood. However, this document is not intended to determine the effectiveness of wood preservatives used to prevent decay. NOTE 1 Determining the efficacy of wood preservatives used to prevent decay is the scope of EN 113-1. However, in addition to this and with some amendments, it might also be possible in some cases to test treated wood using the method described here. NOTE 2 This method can be used in conjunction with an ageing procedure, for example EN 73 or EN 84. Annex A (informative) contains a guidance on sampling. Annex B (normative) contains some methods of sterilization. Annex C (informative) contains information on the culture vessels. Annex D (informative) contains an example of a test report. Annex E (informative) contains information on the test fungi. Annex F (informative) contains the assessment of the results.
