Mike, Page 22 of our company copy of EN 61010-1:1993 refers to:
very fast = FF or black fast = F or red medium, time-lag = M or yellow time-lag = T or blue long time-lag = TT or grey There is a reference to these code/color designations coming from IEC 127. There are some other "trade" fuse designations such as "slo-blo". My experience is that "slo-blo" has similar ratings to a type "T" fuse according to IEC 127. Of course, you have to check the manufacturer's data sheets to see what standard they used for ratings ... Hope this helps.
