NOTE This International Standard establishes fastener holding performance of screws commonly used in applications involving wood-based panels used for building, furniture, cabinet making, joinery or other work in particular regions. Different screws will give different results. 2 Normative references The following referenced documents are indispensable for the application of this document.
