This part of ISO 11093 specifies a method for the determination of the maximum flat crush resistance of wound paper and board cores. NOTE If the wall thickness of the core is less than 5 mm, the breaking point is not detectable.
Abstract
Overview
ISO 11093-9:2019 defines a standardized method to determine the maximum flat crush resistance of wound paper and board cores. The procedure measures the load acting at right angles to the core axis at the first maximum (or levelling off) of the crushing force. Results are reported in and are intended to provide consistent core strength data for design, quality assurance and conversion processes.
