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.
