ISO 13347-3:2004 applies to industrial fans as defined in ISO 5801 and ISO 13349. It is limited to the determination of airborne sound emission for the specified set-ups. Vibration is not measured, nor is the sensitivity of airborne sound emission to vibration effects determined. The sizes of fan which can be tested in accordance with ISO 13347-3:2004 are limited only by the practical aspects of…

ISO 8858-3:2004 describes a laboratory method for release evaluation of the froth flotation characteristics of hard coal, of particle size less than 0.5 mm. It is applicable to coal in powder form or in the form of a slurry.

ISO 8858-2:2004 sets out a laboratory sequential procedure for the froth flotation testing of fine coal, e.g. coal having a particle size of less than 0,5 mm. The procedure provides a means of evaluating for a coal the flotation characteristics (expressed as a yield/ash relationship) that may be expected from the froth flotation process. Pulp samples that cannot be dewatered without the use of…

ISO 19238:2004 provides criteria for quality assurance and quality control, evaluation of the performance and the accreditation of biological dosimetry by cytogenetic service laboratories.

ISO 15198:2004 describes a process for manufacturers of in vitro diagnostic medical devices to validate quality control procedures they recommend to their users. These quality control procedures are intended to provide users with assurance that device performance is consistent with its intended use and the manufacturers' claims. ISO 15198:2004 applies to all in vitro diagnostic medical…

Describes a method for calculating the minimum approach distances for live working, at maximum voltages between 72,5 kV and 800 kV. This standard addresses system overvoltages, and the working air distances between parts and/or workers at different potentials. The required withstand voltage and minimum approach distances calculated by the method described in this standard are evaluated taking…

Establishes a common and reproducible reference for evaluating the immunity of electrical and electronic equipment when subjected to electrical fast transient/bursts on supply, signal, control and earth ports. The test method documented in this part of IEC 61000-4 describes a consistent method to assess the immunity of an equipment or system against a defined phenomenon. The standard defines…

ISO 17313:2004 specifies a test method for laboratory measurement of the hydraulic conductivity of water-saturated porous materials using a flexible wall permeameter. ISO 17313:2004 is applicable to undisturbed or compacted specimens that have a hydraulic conductivity between 1 x 10-5 m/s (1 x 10-3 cm/s) and 1 x 10-11 m/s (1 x 10-9 cm/s). Typical soil types falling in this category are clay, clay…

ISO 20905:2004 sets out a laboratory procedure for the dust testing of higher rank coals. The procedure defines a means of evaluating the dust/moisture relationship characteristic of a coal and a dust extinction moisture (DEM).

ISO 11275:2004 specifies a laboratory method for the simultaneous determination in soils of the unsaturated hydraulic conductivity and of the soil water-retention characteristic. It is applicable only to measurement of the drying or desorption curve. Application of the method is restricted to soil samples which are, as far as possible, homogeneous. The method is not applicable to soils which…
