I am not an expert, however from personal experience film speed (ASA) was not standardised. It was a result of what the technology of the time was capable of and not a linear progression.
For example Kodak colour slide film I used was 25 ASA, 64ASA, 100ASA (Kodachrome) and 160ASA (High Speed Ectachrome).

With digital sensors & ISO (The ASA equivalent) the ISO is determined by how much the signal from the sensor is boosted. (elctronically).

Is Kodak gone?
