You can destructively test samples out of a box of them. But even then the proper current profile that a fuse is supposed to accept or block is far from obvious

You can destructively test samples out of a box of them. But even then the proper current profile that a fuse is supposed to accept or block is far from obvious or intuitive. Reading the spec helps. And then you still have the problem of supplying an acceptable sequence to get a correct result as you desired.
Another option is to experimentally send through various current profiles so that you - more intuitively - get a better understanding of whether your thinking of what you want to protect from, might actually happen.

Even if you shove the standards in front of their faces, most engineers don't know what fuses really do (prevent fires) or what they don't (save circuit boards) or how fast it happens (not very). Asking your typical engineer to test a fuse lot is not going to give a useful result. This is why there are so very many safety agency marks on fuses and why even the Chinese often skip the BS and just pay for name brand fuses.
