Which Appendix defines unit of measurement, symbols, and abbreviations along with conversion factors?

• A. Appendix A Glossary
• B. Appendix B Nomenclature
• C. Appendix C Currently Assigned Substances
• D. Appendix D Competent Authorities

Answer: (B)

Nomenclature is the part that standardizes measurement terms, symbols, and how to convert between units. This appendix compiles and defines the official units of measurement, the symbols used (for example, m for meter, L for liter), and common abbreviations, along with the conversion factors between units. Having these standards ensures everyone interprets data consistently and can perform accurate calculations across documents and procedures. A Glossary places general term definitions, which may not cover the specific set of units or conversion relationships. The other appendices address topics like substances or regulatory authorities, not measurement conventions. So the Nomenclature appendix is the correct one.
