GB/T 2423.30-2013 "Environmental Testing—Part 2: Test Methods—Test XA and Guidance: Immersion in Cleaning Solvents" is a modification and adoption of relevant international standards, aligning with environmental protection requirements by removing content related to environmentally harmful solvents. It applies to electronic components and other parts mounted on printed circuit boards, specifying test methods for immersing samples in cleaning solvents under specific temperatures and durations. The standard clearly defines temperature and immersion time requirements for two types of solvents: industrial isopropanol and soft or distilled water, covering both wiping and non-wiping test procedures. It standardizes the requirements for initial inspection of samples, immersion operations, drying and recovery, as well as final inspections of appearance, electrical performance, and mechanical properties. The standard is used to evaluate the extent to which components are affected by immersion in cleaning solvents, providing technical support for the quality control of electronic components.
