The torque setting's are usually marked on the components, if the components are supplied as stock, you would
generally be ok to assume the marking on the components matches the spec of the frame (but it is worth checking). If you have changed components, you will want to double check against the frame spec (you should have a manual, otherwise contact the manufacturer).
Usually seatpost clamps are in the range of 6-8Nm, Stems somewhere similar, mine range from 5-6Nm and 8-10Nm. The front plate's tend to be around 4-6Nm. On my carbon bike (with carbon forks and steerer), all parts are marked 6Nm! The manufacturer of the frame provides a bespoke seatpost clamp for the frame due to aero profile, and the stem and h-bars are the same brand as the frame.
Most aluminium stems seem to be labelled up with 5-6 Nm... which doesn't sound much to me.
True, but if you tighten to that torque then get a normal multitool or hex key at it, you soon realise it is fairly tight, I was surprised how low a value I had been torquing too when working with normal hex key's and no torque wrench.
