ISO/IEC 12119 is the standard titled 'Information technology - Software packages - Quality requirements and testing'. It specifically defines quality requirements for software packages. The other standards serve different purposes: 14143 covers software measurement (function point analysis), 15271 addresses IT service management, 15504 is process assessment (SPICE), 12207 covers software life cycle processes, and 15939 covers measurement processes.
ISO/IEC 12119 specifically defines quality requirements and testing instructions for software packages (off-the-shelf software products). The other standards listed cover different areas — 14143 is functional size measurement, 15504 is process assessment (SPICE), and 12207 covers software life cycle processes — so they don't match this particular scope.
