Over deze norm
This part of ISO 22389 specifies the component performance and manufacturing requirements for prefabricated wood-based I-beams used as structural members in bending applications. It does not cover fire performance, formaldehyde requirements and biological durability. This part of ISO 22389 gives requirements for manufacturing, in-house quality assurance and periodic reevaluation of prefabricated wood-based I-beams. Wood-based I-beams tested according to this part of ISO 22389 are intended for use in covered conditions and utilize components that are able to resist the effects of moisture on structural performance due to construction delays or other conditions of similar severity, but not permanently exposed to the weather.
