Re: Any standred to charge the R134a in any refrigerator
You need to charge by superheat and subcooling regardless of refrigerant.
Correct superheat ensures that there is no liquid at compressor suction (because liquid cannot be compressed) and if it is to low compressor could be damaged and if it is to high, evaporator capacity is lowered, because that excess superheat is not useful.
Correct subcooling ensures that liquid is present at inlet of expansion device, and if it is low, some evaporated refrigerant enters in expansion device lowering device capacity and, also, could damage it (TXV). High subcooling uses higher part of condenser for storing liquid refrigerant, and lowers his heat rejection capacity.
Refrigerant charging must be balanced in that manner that is in all working conditions ensured minimum superheat and minimum subcooling and in same time that useless subcooling and superheat is also minimal.
Amount of superheat and subcooling is dependent on construction of appliances and working conditions in time of charging.
Good guide for AC is Jim Wheeler charging article:

As Nike has said, there is no "standard" charge, the charge must be tuned to your fridge.
Add refrigerant till you just begin to see frost on the suction line, then with this charge allow the fridge to pull down to the temperature of 2C, then you adjust the charge to get proper super heat and sub cooling.
After this you will watch it and test it at several different condensing temperatures to ensure it is good then seal it off.
Good luck to you and your venture, I am sure you will succed.

No company, no designation! I work from job to job for cash money (tax free :D).
Why do you ask that?
