SIST EN 60851-5:2009/A2:2020

Overview

SIST EN 60851-5:2009/A2:2020 is a European Standard published by CLC that specifies test methods related to the electrical properties of winding wires. It serves as an amendment to the original EN 60851-5:2008 standard, incorporating updated procedures and requirements to ensure high-quality evaluation of winding wire performance. The standard aligns with IEC 60851-5:2008/A2:2019 and applies across various industries involving electrical winding wires, including copper and aluminum types.

Winding wires are critical components in electrical machines, transformers, and inductors, where their electrical properties directly affect operational reliability and efficiency. This standard supports the consistent assessment of those properties, strengthening product quality and safety compliance.
