The upcoming national standard stipulates that only when the UPF is greater than 30 and the UVA transmittance is less than 5%, it can be called an anti-ultraviolet product, and the protection level is marked as UPF30+; and when the UPF is greater than 50, it indicates that the product’s Ultraviolet protection performance is excellent, and the protection level is marked as UPF50+.
