GB/T 44202-2024 "Preparation of Test Samples for Assessing the Aging Degree of Museum Silk Textiles" specifies the requirements for sampling, handling, preparation, and information registration of test samples used to evaluate the aging degree of museum silk textiles. It applies to the pretreatment of samples for various testing methods, such as amino acid analysis, scanning electron microscopy, and thermogravimetric analysis. Sampling should prioritize fragments or non-critical areas, using neutral tools to avoid contamination. Samples are rinsed with anhydrous ethanol and air-dried in the shade, with some test samples requiring conditioning in specific temperature and humidity environments. Different detection instruments correspond to dedicated preparation methods, while comprehensive records of sample sources and preparation information must be maintained. This standard provides a standardized basis for sample preparation in the detection of silk textile aging.
