Hi, gentlemen. Can you please reference what standards writing body (ISO, ASTM, JS, BS, etc.) and what standard you are referring to?
Trying to determine the meaning of a string of numbers and letters without that context reminds me of crime novels where the dieing victim scrawls a number on the wall in his own blood and the detective spends the next 250 pages trying to figure out its meaning :-)
Good luck.
