The baby diaper market is rapidly growing, while product quality and safety issues have also attracted increasing attention. GB/T 28004.1 and GB 15979 are key standards in China for regulating the quality and safety of baby diapers. GB/T 28004.1 specifies product performance and quality requirements, while GB 15979 focuses on hygiene safety requirements, including critical indicators such as microbial contamination control.
