Reference radiation fields for radiation protection — Definitions and fundamental concepts
ISO 29661:2012 defines terms and fundamental concepts for the calibration of dosemeters and equipment used for the radiation protection dosimetry of external radiation -- in particular, for beta, neutron and photon radiation. It defines the measurement quantities for radiation protection dosemeters and doserate meters and gives recommendations for establishing these quantities. For individual…
Mechanical vibration and shock — Characterization of the dynamic mechanical properties of visco-elas...
ISO 18437-1:2012 establishes the principles underlying ISO 18437-2 to ISO 18437-5 for the determination of the dynamic mechanical properties (i.e. elastic modulus, shear modulus, bulk modulus, loss factor, and Poisson ratio) of isotropic visco-elastic resilient materials used in vibration isolators from laboratory measurements. It also provides assistance in the selection of the appropriate part…
Soil quality — Biological methods — Determination of nitrogen mineralization and nitrification in so...
This International Standard specifies laboratory procedures for measuring the mineralization and nitrification of nitrogen by the soil microbiota.
For investigations on the evaluation of soil quality or on effects of contamination, a procedure is given to measure the rates and extent of N-mineralization in soil or soils of known or unknown quality.
For investigation of the potential toxicity of…
Electroacoustics - Methods to determine corrections to obtain the free-field response of a sound lev...
IEC 62585:2012 provides information on the corrections required over a range of frequencies in order for a periodic test of a sound level meter to be performed according to IEC 61672-3. These corrections include; corrections for the typical effects of reflections from the case of the sound level meter and diffraction of sound around the microphone; corrections for the deviation of the typical…
