ISO 24336:2005规定了在部分浸入水中后测定层压板地板覆盖件厚度膨胀的试验方法。该测试具有破坏性，主要用于评估层压板地板覆盖件与水接触时的性能。试验中不包括可能预先附着的软背衬材料、子层或集成在地板覆盖件下侧的任何其他材料，因此应在试验前移除。

ISO 24336:2005 specifies a test method for the determination of thickness swelling of laminate floor-covering elements after partial immersion in water. The testing is destructive and is mainly intended to evaluate the behaviour of the laminate floor-covering element in contact with water. Possible pre-attached soft backing material, sub-layers or any other material integrated at the underside of the floor-covering element are not included in the test and should therefore be removed before testing.
