发布日期：2012-01
标准范围
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.NOTE The service conditions are similar to “Service class 2” as defined in ISO 20152-1.Testing, evaluation, and performance characterization requirements for prefabricated wood-based I-beams are covered in ISO 22389-1.This part of ISO 22389 does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this part of ISO 22389 to establish appropriate health and safety practices and determine the applicability of regulatory limitations prior to use.
