The PDF provides formulas to calculate the average peeling force, ignoring the initial and final 20% of the curve. Iso 8339 Pdf
It is common to confuse ISO 8339 with other standards. Here is a quick differentiation: : 28 days at standard room temperature and
The test requires a tensile testing machine capable of maintaining a constant rate of extension (typically Conditioning: The test continues until the sealant ruptures, and
The conditioned specimens are placed in a tensile test machine capable of a steady extension rate of approximately . The test continues until the sealant ruptures, and the force-extension relationship is recorded. Key Metrics Measured
Specifically, the standard describes a test method for measuring the force required to separate the textile reinforcement from the surrounding rubber layers (cover and lining). While there are multiple parts to the adhesion testing family (ISO 8033 for fabric, ISO 8339 for specific tensile methods), ISO 8339 focuses on a strip test method for hoses with a parallel arrangement of textile yarns.
