ISO 22390:2020 PDF Download

ISO 22390:2020 standard outlines the requirements for determining the key properties of structural laminated veneer lumber (LVL). This standard focuses on establishing characteristic properties, such as 5th percentile strength values and stiffness characteristics, that are relevant for LVL's structural application in dry conditions (service class 1). The standard applies to LVL members used in both flatwise and edgewise bending orientations.

However, it is important to note that ISO 22390:2020 does not cover other aspects related to LVL assessment, such as formaldehyde requirements, biological durability, fire performance, or manufacturing processes like quality control and marking. These factors are not within the scope of this particular standard.
