What is EN ISO 17491-4:2019?

EN ISO 17491-4:2019 is a technical standard that provides guidelines and requirements for the determination of certain properties of adhesives. It is part of the ISO 17491 series, which focuses on adhesives for both industrial and consumer applications.

Scope and Purpose

The scope of EN ISO 17491-4:2019 includes the determination of shear behavior, creep resistance, and durability of adhesive bonds under various test conditions. This standard is applicable to adhesives used in a wide range of industries, including automotive, aerospace, construction, and electronics.

The purpose of this standard is to ensure consistency and reliability in the testing and evaluation of adhesive properties. By following the guidelines set forth in EN ISO 17491-4:2019, manufacturers, researchers, and quality control professionals can effectively assess the performance of adhesives and make informed decisions regarding their suitability for specific applications.

Testing Methods and Requirements

EN ISO 17491-4:2019 outlines the testing methods and requirements for determining shear behavior, creep resistance, and durability of adhesive bonds. These tests involve subjecting the adhesives to various mechanical and environmental stresses to evaluate their performance characteristics.

For shear behavior, the standard specifies the use of different testing configurations, such as lap shear, butt shear, or peel shear, depending on the intended application. The results obtained from these tests provide valuable information on the adhesive's ability to withstand forces parallel to the bond line.
