Acoustics — Measurement of noise inside railbound vehicles
Specifies the conditions for obtaining reproducible and comparable measurement results of the noise level and the noise spectrum. The results may be used f. e. for comparison, for characterization of acoustic comfort, for orientation a program of more elaborate measurements for the purposes of studying noise reduction procedures.
Numerical control of machines — Axis and motion nomenclature
This edition cancels and replaces the ISO Recommendation R 841-1968. Defines axis and motion nomenclature, and is intended to simplify programming and to facilitate the interchangeability of recorded data. Applies to all numerically controlled machines.
Information technology — Portable Operating System Interface (POSIX®) base specifications — Issue 8
ISO/IEC/IEEE 9945:2009 defines a standard operating system interface and environment, including a command interpreter (or "shell"), and common utility programs to support applications portability at the source code level. ISO/IEC/IEEE 9945:2009 is intended to be used by both application developers and system implementers and comprises four major components (each in an associated volume…
Systems and software engineering — Life cycle management — Part 7: Application of systems engineerin...
This document establishes the requirements for systems engineering activities to be performed on projects of the United States (US) Department of Defense (DoD) and other defense agencies across the entire system life cycle, including the planning, acquisition, modification, and sustainment of defense systems. It provides the foundation for systems engineering within the context of ISO/IEC/IEEE…
