GB/T 46428.1-2025 is the first part of the series of standards for plate-shaped and rod-shaped miniature samples of metal materials. It stipulates the principle, sample prepative, operation process and data processing requirements of fatigue test of such miniature samples, and is suitable for fatigue performance testing of miniature samples of various metal materials. The standard provides a unified technical basis for metal material research and development, parts quality control and engineering application Reliability assessment, guarantees the accuracy and comparability of test data, and helps to standardize the fatigue test process of miniature samples.
