ISO/IEC Guide 2:2004 provides general terms and definitions concerning standardization and related activities. It is intended to contribute fundamentally towards mutual understanding amongst the members of ISO and IEC and the various governmental and non-governmental agencies involved in standardization at international, regional and national levels. It is intended also to provide a suitable…

ISO 18278-2:2004 specifies a laboratory test procedure for the determination of the acceptable welding current range and the assessment of electrode life using a multi-spot test with specific conditions. ISO 18278-2:2004 is applicable for the assessment of the weldability of uncoated and coated sheet steels of thicknesses up to 3 mm. The test procedure specified in this International Standard and…

ISO 5269-2:2004 specifies a method, using a Rapid-Köthen sheet former, for the preparation of laboratory sheets of pulp for the purpose of carrying out subsequent physical tests on these sheets in order to assess the relevant properties of the pulp itself. ISO 5269-2:2004 is applicable to most kinds of pulp. It is not suitable for some pulps with very long fibres, such as those made from…

ISO 10650-1:2004 specifies requirements and test methods for powered polymerization activators in the blue wavelength region intended for chair-side use in polymerization of dental polymer-based materials. ISO 10650-1:2004 applies to powered tungsten-halogen lamps and rechargeable battery-powered tungsten-halogen polymerization activators. ISO 10650-1:2004 is not applicable to powered…

ISO/TS 17892-1:2004 specifies the laboratory determination of the water (moisture) content of a soil test specimen by oven-drying within the scope of the geotechnical investigations according to prEN 1997-1 and prEN 1997-2. The water content is required as a guide to classification of natural soils and as a control criterion in re-compacted soils and is measured on samples used for most field and…

ISO/TS 17892-2:2004 specifies methods of test for the determination of the bulk and dry density of intact soil or rock within the scope of the geotechnical investigations according to prEN 1997-1 and prEN 1997-2. The bulk density of a soil is useful in the determination of the in-situ overburden stresses at various depth (geostatic stresses). Furthermore, bulk and dry density can qualitatively…

ISO/TS 17892-3:2004 describes a test method for determining the particle density by the pycnometer method within the scope of the geotechnical investigations according to prEN 1997-1 and prEN 1997-2. The pycnometer method is based on the determination of the volume of a known mass of soil by the fluid displacement method. The density of solid particles is calculated from the mass of the soil and…

ISO/TS 17892-4:2004 describes methods for the determination of the particle size distribution of soil samples. The particle size distribution is one of the most important physical characteristics of soil. Classification of soils is mainly based on the particle size distribution. Many geotechnical and geohydrological properties of soil are related to the particle size distribution. The particle…

ISO/TS 17892-5:2004 is intended for determination of the compression, swelling and consolidation properties of soils. The cylindrical test specimen is confined laterally, is subjected to discrete increments of vertical axial loading or unloading and is allowed to drain axially from the top and bottom surfaces. The main parameters derived from the oedometer test relate to the compressibility and…

ISO/TS 17892-6:2004 specifies the laboratory determination of undrained shear strength of both undisturbed and remoulded specimen of saturated fine grained cohesive soils by use of a fall-cone. This document specifies the fall-cone test, in which a cone is allowed to fall with its tip towards a soil specimen, whereupon the penetration of the cone into the soil is measured. Tests performed…
