On the Validity Period of Medical Device Products

I didn't pay much attention to the shelf life of products before. When aseptic products are produced, people are not interested in the shelf life. However, after 20 14 10 1, all medical devices (including in vitro diagnostic reagents) have clear requirements for the validity period, but the requirements for the validity period are not very clear. Sterility is generally three years, in vitro diagnostic reagents are generally one year, and active products may be five, seven or sixty years.
