Could it be a counterfeit sub-standard fuse from the far East? We are frequently hearing of products with fake approval marks entering the UK market. I recall warnings about exploding plug fuses with false approvals. BTW I had a look at some of the fuses in plugs around the house & lying in my tool trays, they all had the BSI Kitemark & ASTA approval marks, no other approvals.
