I did a quick short circuit test in a socket with a relatively low PSCC, it failed as one of the caps blew off.
New value BS1362 fuse

Well, I presume that it interrupted the circuit, so some might not call it a failure
... but it's a rather odd failure mode. Was the fuse in a plug? (I wouldn't have thought that many plugs would afford an opportunity for the cap to blow off!). Have you tried the same with a 'proper' 13A fuse?Kind Regards, John
Yes fuse was in plug, 13A fuse did not blow apart.
Fair enough. I must say that I'm not sure what features will make a fuse blow apart when faced with very high currents - or what I could do (other than putting gunpowder, rather than sand, inside it!) if, for whatever reason, I wanted to design one that would!
Kind Regards, John

Fit the end cap loose, and use damp sand!
I may be wrong, but I'm not convinced that the end caps are necessarily all that well attached. I suppose that damp sand might well do it, but I'm not sure why anyone would use that (no cheaper than dry sand!)!
Kind Regards, John
Probably loose caps, though I couldn't pull them off by hand like you can in the really awful ones. I imagine it must be quite hard to contain the blast in large fuses rated in Ks of amps or where fault currents are extreme. I have a 63A 12KV fuse here it is really heavy, the ceramic tube must be quite thick.
It costs money to keep sand dry!
