Hi all, I am trying to find some data that will show me the typical lifespan for a wave pallet. I realize that it depends on material used (Durapol, for instance) temp profile, etc and I HAVE checked the fine SMT archives... Anyone have an average n

Different viruses have different lifespans outside the host. HIV is something like a few seconds. The flu is something like 12 hours. Sars is something like 24 hrs. There are a lot more deadlier deseases. I think you would have a much greater chance
