Is GB/T 2423.4-2008 an international standard?

GB/T 2423.4-2008 is not an international standard but a Chinese national standard. "GB/T" stands for "Guo Biao/Tui" (National Standard/Recommended), which is formulated and issued by the General Administration of Quality Supervision, Inspection and Quarantine of China (CNCA) and the Standardization Administration of China (SAC).

GB/T 2423.4-2008 is a standard related to "Environmental Testing for Electric and Electronic Products—Part 2: Test Methods—Test Db: Damp Heat, Cyclic (12 h + 12 h cycle)." It specifies the test methods and requirements for electric and electronic products under cyclic damp heat conditions.

Although GB/T 2423.4-2008 is a Chinese national standard, its content and testing methods may be similar or closely related to international standards. In international trade and cooperation, countries may refer to such national standards and adopt, modify, or adjust them as needed. If compliance with specific international standards is required in global trade, it may be necessary to convert or adhere to the relevant international standards to meet those requirements.
