GB/T 46052-2025 in English

This standard outlines a method for assessing the corrosion of metals and alloys under conditions of humid atmosphere containing sulfur dioxide. The procedure involves the use of a fixed gas system to simulate environmental exposure. It provides detailed guidelines on test setup, sample preparation, and measurement techniques to ensure consistency and reliability in corrosion testing. The standard specifies the conditions under which the test is conducted, including temperature, humidity, and gas concentration levels. It also includes procedures for data collection and interpretation. The methodology is designed to facilitate comparative analysis of materials under standardized conditions. The standard is applicable to a wide range of metallic materials and is intended for use in both research and industrial settings.
