Mesurage de la radioactivité dans l'environnement — Air: radon 222 — Partie 7: Méthode d'e...
L'ISO 11665-7:2012 donne des lignes directrices pour estimer le flux surfacique d'exhalation du radon 222 sur une courte période de temps (quelques heures), en un point donné, à l'interface entre un milieu (sol, roche, matériau de construction posé, mur, etc.) et l'atmosphère. Cette estimation est réalisée en mesurant l'activité volumique du radon exhalant de la surface…
Measurement of radioactivity in the environment — Air: radon-222 — Part 7: Accumulation method for e...
ISO 11665-7:2012 gives guidelines for estimating the radon-222 surface exhalation rate over a short period (a few hours), at a given place, at the interface of the medium (soil, rock, laid building material, walls, etc.) and the atmosphere. This estimation is based on measuring the radon activity concentration emanating from the surface under investigation and accumulated in a container of a…

CISPR 16-1-4:2010+A1:2012 specifies the characteristics and performance of equipment for the measurement of radiated disturbances in the frequency range 9 kHz to 18 GHz. Specifications for antennas and test sites are included. The requirements of this publication apply at all frequencies and for all levels of radiated disturbances within the CISPR indicating range of the measuring equipment.…
Power transformers - Part 18: Measurement of frequency response
IEC 60076-18:2012 covers the measurement technique and measuring equipment to be used when a frequency response measurement is required either on-site or in the factory either when the test object is new or at a later stage. This standard is applicable to power transformers, reactors, phase shifting transformers and similar equipment.
Transformateurs de puissance - Partie 18: Mesure de la réponse en fréquence
La CEI 60076-18:2012 couvre la technique de mesure et l'appareillage de mesure à utiliser lorsqu'une mesure de réponse en fréquence est requise, soit sur site, soit en usine, lorsque l'objet à soumettre à essai est neuf ou à un stade plus avancé. La présente norme est applicable aux transformateurs de puissance, bobines d'inductance, transformateurs déphaseurs et appareillages…

Environmental monitoring of the impacts from marine finfish farms on soft bottom
This International Standard establishes an approach for sampling and empirical measurement of soft-bottom
impacts from marine finfish net pen farms, and gives examples of detailed procedures for how environmental
impacts from finfish net pen farm sites can be monitored in the field, including guidelines for quality assurance
of sampling protocols and safety. The emphasis of the environmental…
