GB/T 45517-2025 《Determination of phenol in toys and children's products—High performance liquid chromatography》 Related products

GB/T 45517-2025 "Determination of phenol in toys and children's products" High performance liquid chroma-tography, HPLC "is an important standard for the safety inspection of children's products in our country. The standard is proposed by the China Light Industry Federation and will be officially implemented on November 1, 2025 by the National Toy Standardization Technical Committee. The standard adopts High performance liquid chroma-tography, HPLC (HPLC) to accurately determine the phenol content in toys and children's products, with the characteristics of high Sensitivity and Repeatability. The standard specifies key links such as sample pretreatment, instrument analysis conditions, standard Linear dispersion establishment and quality control, and is suitable for chemical safety testing of various toy materials and children's products. The implementation of this standard will provide important technical support for ensuring children's health and safety and standardizing market order.
