ISO 17892-2:2014 specifies three methods for the determination of the bulk density of soils, comprising: a) linear measurement method; b) immersion in fluid method; c) fluid displacement method. ISO 17892-2:2014 is applicable to the laboratory determination of the bulk density of soil within the scope of geotechnical investigations. The linear measurement method is suitable for the determination…

ISO 15007-1:2014 defines key terms and parameters applied in the analysis of driver visual behaviour focused on glance and glance-related measures. These terms and parameters can be applied in environments from real-world driving experiments to laboratory-based driving simulator studies. The procedures described in this part of ISO 15007 could also apply to more general assessments of driver…

IEC 61482-1-2:2014 specifies procedures to test material and garments intended for use in heat and flame-resistant clothing for workers if there is an electric arc hazard. A directed and constrained electric arc in a test circuit is used to classify material and clothing in two defined arc protection classes. This International Standard is not dedicated toward measuring the arc rating values (…

IEC 61010-2-010:2014 specifies safety requirements for electrically powered laboratory equipment for the heating of materials, where the heating of materials is one of the functions of the equipment. This third edition cancels and replaces the second edition published in 2003. It constitutes a technical revision and includes the following significant changes from the second edition, as well as…

ISO 16251-1:2014 specifies a laboratory measurement method to determine the improvement of impact sound insulation by a floor covering when laid on a standard concrete floor mock-up and excited by a standard tapping machine. The method is restricted to soft, flexible floor coverings, which transmit impact sound mainly "locally" into the floor, i.e. through the area close to the points…

ISO 14388-1:2014 provides a general introduction to acid sulfate soils and the approaches that can be used to measure the various components of this special group of soils and their potential to produce acidity. It provides a compilation of the test methods, identification and definitions of the symbols, terms, and acronyms used in this series of ISO 14388. While part of the decision-making…

ISO Guide 80 outlines the essential characteristics of reference materials for quality control (QC) purposes, and describes the processes by which they can be prepared by competent staff within the facility in which they will be used (i.e. where instability due to transportation conditions is avoided). The content of this Guide also applies to inherently stable materials, which can be transported…

ISO 5631-3:2014 specifies a method for measuring the colour of paper and board by the diffuse reflectance method with the elimination of specular gloss. ISO 5631-3:2014 is primarily intended for measuring the colour of paper and board to be used in the graphic arts industry, where that industry specifies the measurement of colour under D50/2° conditions in accordance with ISO 13655. This method…

ISO 5631-2:2014 specifies a method for measuring the colour of paper and board by the diffuse reflectance method with the elimination of specular gloss. It can be used to determine the colour of papers or boards that contain fluorescent whitening agents, provided the UV content of the illumination on the test piece has been previously adjusted to give the calibrated colourimetric value…

ISO 17289:2014 specifies an optical method for the determination of dissolved oxygen in water using a sensor working on the basis of fluorescence quenching. Measurement can be made either as a concentration of oxygen in milligrams per litre, percentage saturation (% dissolved oxygen), or both. Depending on the instrument used, detection limits of 0,1 mg/l or 0,2 mg/l can be reached according to…
