Jerry, You can indeed put your fingers into a bayonet or Edison screw lamp socket if you are so inclined. Some new models isolate the contacts when the bulb is removed though. However they are not covered by the standard under discussion. This is one of the anomalies of safety standards that they do not all have the same level of safety.
How much would it cost the world to change from the bayonet cap fitting though - how many millions are in use right now? As per many standards the decision is commercially motivated............... new homes have RCD breakers so people are protected, the home being where most people are most at risk. Getting back on track however, we were talking about IEC 1010 or more correctly IEC 61010 (EN 61010) Safety requirements for electrical equipment for measurement, control, and laboratory use. I don't have a full copy to hand but it is not far removed from EN 60065 or 60950 both of which require tool fitted covers.
