When a manufacturer quotes a frame size, what does it actually mean eg D 315 SD

A standard metric motor, e.g. D315sd. The 315 relates to the height of the shaft in relation to the ground i.e. when the motor is lying on a flat the height from the ground is 315mm high. The "s" part of the type number relates to the fixing holes that are in the feet of the motor, either "m" or your case "s" which looking at the side of the motor will have a dimension of 406mm.
The frame size will also tell us the diameter of the shaft but can alter depending on the speed of the motor for example a D315s 2 pole motor(3000 rpm) will have a shaft size of 65mm, while a D315s 4 pole motor(1500 rpm) will have a shaft size of 80mm)

In a catalogue of motors, you usually have a series of dimentional drawings, and a list of data related to the motors.
You select the motor you want by its characteritics, read the "frame size" of that motor, go to the drawing list, find the mechanical details of your motor.
It changes from one manufacturer to another. There is no standard as far as I know.

frame sizing is an international norm meant to deliver the proper tourqe and hp. with the application and design.
can it be changed?
yes anytime ya want
just
need simple math and changes in (framing) mounting of the motor
all done

Depends on the power which decides the shaft size which in turn decide the rotor and frame sizes
