Acoustics — Measurement of sound absorption properties of road surfaces in situ — Part 2: Spot metho...
ISO 13472-2:2010 specifies a test method for measuring in situ the sound absorption coefficient of road surfaces for the one-third-octave-band frequencies ranging from 250 Hz to 1 600 Hz under normal incidence conditions. For special purposes, the frequency range can be changed by modifying the dimensions of the system.
The test method is intended for: a) determination of the sound absorption…
Health informatics — Public key infrastructure — Part 4: Digital signatures for healthcare documents
This document supports interchangeability of digital signatures and the prevention of incorrect or illegal digital signatures by providing minimum requirements and formats for generating and verifying digital signatures and related certificates.
