Just a quick question. When looking at the CT standards from AABB there is either a C or F beside certain standards. Just wanted to know if someone could tell me what that stands for ?

Thanks

I did not find the explanation in the 6th edition of the CT standards, but if you look in older versions you will see in the Preface its meaning. CT standards 5th edition states: “The pen symbol is preceded by the letter C or F. The C and F requirements describe from what point in the process the clock starts for determining how long the record must be kept. The records are required to be retained for at least 10 years following either their creation "C" or the final disposition of the product "F".
