This part of ISO 10705 specifies a method for the detection and enumeration of bacteriophages infecting Bacteroides fragilis by incubating the sample with an appropriate host-strain. The method is applicable to all kinds of water, sediments and sludge extracts, where necessary after dilution. In the case of low phage numbers, a preconcentration step may be necessary for which a separate…

This International Standard, known as the Interchange Standard for Multimedia Interactive Documents or ISMID, facilitates the interchange of Multimedia Interactive Documents (MIDs) among heterogeneous interactive document development and delivery systems by providing the architecture from which common interchange languages can be created. ISMID is a client architecture of International Standard…

This International Standard specifies the physical and magnetic characteristics of an 8 mm wide magnetic tape cartridge to enable physical interchange of such cartridges between drives. It also specifies the quality of the recorded signals, the recording method and the recorded format called VXA-1, and thereby allowing data interchange between drives by means of such magnetic tape cartridges.…

This International Standard a) specifies the coded representation of the characters; b) specifies a repertoire of the Latin alphabetic and non-alphabetic characters for the communication of text in many European languages using the Latin script; c) specifies rules for the definitions and use of graphic character subrepertoires, i.e. subsets of the specified character repertoire.

This International Standard presents the general methodology governing the design of neutron radiation protection shielding and the choice of neutron radiation protection shielding materials. This International Standard is applicable to facilities and operations where neutron sources are located and used, and where workers are occupationally exposed. These operations and facilities vary…

This International Standard specifies requirements for fine-tolerance hoist chain of Grade T (types T, DAT and DT) for use with manually operated or power-driven chain hoists1). It is applicable to electrically welded, round, steel short-link chain, heat-treated and tested in accordance with the general conditions of acceptance of ISO 1834, in the nominal chain size range from 3 mm to 22 mm. NOTE…

This International Standard specifies the general requirements for the construction as well as the performance of type tests of magnetic compasses on board small craft of hull length up to 24 m. It refers to liquid magnetic compasses, which can be inspected (e.g. not sealed), either equipped with a direct reading system, or of the reflecting/projecting type. This International Standard also…

This International Standard describes a method that uses an electronic hydrogen detection instrument for measuring relative, diffusible hydrogen concentrations in bare steels or in plated steels after the coating has been removed. It is assumed that the hydrogen is uniformly distributed throughout a part. The method does not measure actual hydrogen concentration. However, oxidation current…

This part of ISO 17123 specifies field procedures to be adopted when determining and evaluating the precision of levels (spirit levels, compensator levels, digital levels) and their ancillary equipment when used in building and surveying measurements. Primarily, these tests are intended to be field verifications of the suitability of a particular instrument for the immediate task at hand and to…
