ISO 19581 specifies a screening test method to quantify rapidly the activity concentration of gamma-emitting radionuclides, such as 131I, 132Te, 134Cs and 137Cs, in solid or liquid test samples using gamma-ray spectrometry with lower resolution scintillation detectors as compared with the HPGe detectors (see IEC 61563). This test method can be used for the measurement of any potentially…

A new International Standard in the area of concrete technology, with specific scope on use of recycled aggregates for concrete, which are produced from construction and demolition wastes including demolished concrete and demolished masonry units. Recycled aggregates include both coarse aggregates and fine aggregates.

This document specifies the minimum requirements for airworthiness approval of air cargo pallets, nets and containers, generally designated as air cargo unit load devices (ULD). This document is intended to provide a uniform technical reference for air cargo unit load devices approval. As a prerequisite, it is presupposed that the applicable general civil aviation requirements and the aircraft…

This International Standard is applicable to radiation shielding design and evaluation work for medical proton accelerators with nominal energies of the beam ranging from 70 MeV to 250 MeV, with subsystem such as beamlines, energy selection system (for cyclotron) and nozzle components. The radiation protection requirements and recommendations given in this international standard cover the…

This International Standard specifies a method for the determination of the electrical resistivity of cathode blocks and baked anodes used in the production of aluminium, using samples at ambient temperature.

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…

Field devices are a key component in intelligent transport systems (ITS). Field devices include traffic signals, message signs, weather stations, traffic sensors, roadside equipment for connected ITS environments, etc. The ISO 26048 series defines data that can be used to manage field devices, including device configuration, control, and monitoring. Field devices can be quite complex,…

This standard describes the basic principles and recommended procedures for corpus annotation project management as its core model. The core model of corpus project management consists of a series of recommended work packages to fulfill the basic requirements for error-free corpus annotation with training the involved human and validating the intermediate results. Thus, the core model contains…

This document specifies an analytical method for the determination of silver on a material considered homogeneous. The silver content of the samples lies preferably between 50 ‰ (parts per thousand) and 990 ‰ (parts per thousand). Fineness above 999,0 ‰ can be determined using a spectroscopy method by difference (e.g. ISO 15096). NOTE Lower contents of silver can be analyzed with this method.

This International Standard identifies and establishes process considerations for service life planning and a systematic framework for undertaking service life planning of a planned building or construction work throughout its life cycle (or remaining life cycle for existing buildings or construction works). The life cycle incorporates initiation, project definition, design, construction,…
