Is the concentration the same as stated in the standard method? If so, Should I use only 1 mL per L?

The product, D4019L, is a concentrated solution. The entire contents of the vial should be emptied into your container and brought up to the appropriate volume (in this case, 19 L). Once the solution is at volume, it is equivalent to 1 mL per L.
