GB 15979 Hygienic standard for disposable sanitary products
There is a difference between these two standards. The former is a product standard, while the latter is only a hygiene standard. GB/T 8939-2008 has already included the requirements of GB 15979, so it is better to choose sanitary napkins that implement the standard GB/T 8939-2008 than GB 15979. In other words, products that only guarantee hygiene requirements are definitely not as good as products that guarantee hygiene requirements and other quality of products.
