GB/T 46542-2025 "Textiles — Test Method for Retroreflective Performance" applies to textiles (including garments and safety protective equipment) containing retroreflective materials or subjected to retroreflective treatment, specifying scientific testing methods for retroreflective performance. It clearly defines the measurement of the coefficient of retroreflection using a standard light source and a photometer, covering test requirements at various incident and observation angles, and includes durability testing after washing. The standard regulates sample preparation, instrument calibration, experimental procedures, and data analysis, detailing technical parameters and criteria for result evaluation. It provides a unified standard for assessing the nighttime visibility of products, ensuring the safety of wearers.
