IEC 63522-11:2025 pdf download,Electrical relays – Tests and measurements – Part 11: Enclosure protection and degree of protection.

IEC 63522-11:2025 is intended for testing electrical relay enclosures, specifying the relevant severities and conditions necessary for measurements and assessments. These tests are designed to evaluate the performance of Devices Under Test (DUTs) under anticipated conditions of transportation, storage, and various operational scenarios.

This document establishes standardized test methods specifically for assessing the effectiveness of enclosure sealing. By defining these testing protocols, it ensures that the enclosures can adequately protect the internal components from environmental factors, thereby enhancing the reliability and longevity of the electrical relays in real-world applications.
