The GB/T 41649-2022 standard specifies a method for the determination of formaldehyde release in wooden toys, which is analyzed by flask method. This method is suitable for all kinds of wooden toy products, and the potential impact of toys on children's health is assessed by simulating formaldehyde release under actual use conditions. The standard specifies the collection and testing steps of samples, providing a scientific basis for toy manufacturers and market supervision to ensure that products meet the standards for safe use.
