Описание (английский):

ISO 11093-6:2005 specifies a three-point method for the determination of the bending strength of cylindrical board cores which meet the following criteria: internal diameter: 50 mm to 300 mm; minimum wall thickness: 5 mm; minimum test length of core (span): 1 100 mm.

Abstract

ISO 11093-6:2005 Overview

Key Topics

Scope and Applicability ISO 11093-6 applies to cylindrical paperboard cores satisfying specific dimensional criteria, focusing on bending strength as an indicator of core robustness.
Test Principle The core sample is placed horizontally on two prism-shaped supports and loaded vertically at the midpoint until failure. This setup simulates bending stress conditions.
Test Apparatus
- Compression testing machine calibrated according to ISO 7500-1
- Two prism supports each with 120° angled faces and rounded edges
- A loading prism to apply the bending force, ensuring uniform contact and accurate force application
Sampling and Preparation Samples should be representative of the batch and conditioned under standardized atmospheric conditions per ISO 11093-1 and ISO 11093-2. At least three specimens with lengths exceeding the test span by 100 mm are required for valid results.
Test Execution Load is applied centrally at a constant speed of 25 ± 2.5 mm/min until the core fractures. The maximum load registered corresponds to the bending strength in kilonewtons.
Reporting Test reports must include complete sample identification, test conditions, individual and average bending strength values, and any deviations from the standard procedure.

Practical Applications

Quality Control in Core Manufacturing Producers of paper and board cores utilize ISO 11093-6 to verify product strength, ensuring cores withstand handling and operational stresses during winding, storage, and transport.
Material Selection and Design Optimization R&D teams apply this standard to compare materials and core designs, facilitating decisions to enhance durability and reduce material costs without compromising performance.
Performance Assessment in Packaging and Converting End-users and converters employ the method to ensure cores meet mechanical specifications critical for safe and efficient reel handling and processing.
Supplier Compliance and Contract Specification ISO 11093-6 provides a basis for contractual agreements between buyers and suppliers, establishing consistent testing criteria for bending strength of paperboard cores.
