What is the meaning of the codes that written on hydraulic hoses? for example SEA 100 R 1 A?

i use these in my work but i let the experts match the line to my needs, it would relate to the hose being a one wire or two wire hose, which is the number of steel braids in the hose, two wire is obviously able to handle more pressure but has a smaller inside diameter which means lower flow rate, it could mean for ' the hose fitter' that the fitting has to be pressed into place and what the minimum out side diameter should be to allow for maximum pressure for the hose and fitting combination. also type of material the hose is made of, like stainless steel braid or just steel wire, etc. that's all i can think of now, i will have to ask more next time i get one made.
