Can I run 3 doubles socked from 16 am rcb

Yes
many thanks for the speedy reply and taking the time to help
As has been said, the answer is 'yes' but, for the record,, the answer would also be 'yes' if the three (or, indeed, any number of) sockets were 'daisy-chained' (a 'radial' circuit').
It is not that uncommon for a Radial circuit to be 16 or 20A on bog standard wiring and such a radial could be daisy chained or three sperate runs from breaker to socket. This can be done with any number of sockets and you would most probably evalute the floor area served and type of expected usage to evaluate the circuit intention rather than the actual number present. you can mix and match as well and it is still a radial circuit.
Might it not be prudent to ask what an RCB is?
Yes, perhaps 'prudent'- although I cannot think of any possible 16A device other than the one "we all know he is referring to", can you?
You are probably right but you don't know.
Plus all the other mistakes in the post.

There are at least two things to think about here.
Firstly, what exactly do you mean by "RCB"? that's not a commonly used acronym! To comply with current standards, your socket circuit needs both overcurrent protection and RCD protection.
* A "MCB" provides overcurrent protection.
* A "RCD" or "RCCB" provides RCD protection
* A "RCBO" provides both.
You need to understand what the devices you are looking at actually do and how they are connected. Post photos and ask if you are unsure.
Secondly you need to think about what the sockets will be used for. BS7671 does not explicitly limit the number of sockets on a circuit, but you should not design installations you anticipate will be overloaded.

I must admit that I had Assumed RCB to be a typo of MCB - yes I know I should Never Assume ! Sorry 
I imagine that nearly all of us assumed likewise.
What else could it possibly be. I don't think anyone is going to find a 16A RCD, in a domestic CU or anywhere else.
Sure, but there's also the matter of common sense. EFLI has pointed out that, strictly speaking, we do not "know" that it is a 16A MCB, but I think one may need to consider the meaning of 'know'. If there are no credible alternatives, I reckon it's reasonable to say that 'we know', isn't it?- yes I know I should Never Assume ! Sorry
More generally, in terms of a large majority of 'facts' that we happily say that 'we know', in a very high proportion of cases we only 'know' because someone else has said/written it, or told us, without our personally having seen any proof/evidence of it's correctness!
True - which is why I personally am no fan of 16A or 20A multiple-sockets circuits - which, at least in theory, can so easily be 'overloaded'.
And what's a 16 am?
