Overview
SIST EN ISO 17279-3:2021 provides a comprehensive framework for test methods used in the micro joining of second generation high temperature superconductors (2G HTS). Developed by the Slovenian Institute for Standardization (SIST) under the ISO 17279 series, this standard outlines requirements and procedures for assessing the quality and performance of joints created during the manufacturing of 2G HTS components. Its primary aim is to ensure that such joints meet stringent electrical, magnetic, and mechanical properties, in alignment with the requirements specified in ISO 17279-1 and ISO 17279-2.
This document is essential for those involved in the welding, micro joining, and quality assurance of superconducting components, providing a uniform approach to testing practices across the industry.
