Hello Joann, I actually know the answer to your question! The code numbers in parentheses after the terms refer to technologies associated with each term. For example, Code #1 refers to General Interconnecting and Packaging Terms, while Code #13 terms are Cleaning Terms. Appendix B of IPC-T-50 lists the codes and technologies. Hope this helps.
