Why so angry??
Now I see it completely different from you EN50131 was not that far off 4737, The Grading was an improvement, alarm confirmation was an improvement, yes there were many things wrong with 50131 PD6662 made it workable (which again brings me back to my point) but you could say the same about 4737. 50131 did mean that I could employ French German and Polish engineers without having to provide to much training as they were already familiar with 50131 and that the purpose of having a EN standard end of the day.
