This International Standard specifies methods for the estimation of measurement uncertainty of chemical and physicochemical methods in single laboratories based on validation data and analytical quality control results obtained within the field of water analysis. NOTE 1 The principles of the estimation of uncertainty specified in this International Standard are consistent with the principles…

This document establishes and specifies uniform test procedures, conditions, equipment and a performance report to permit the direct laboratory performance comparison of air cleaners. The basic performance characteristics of greatest interest are air flow restriction or differential pressure, dust collection efficiency, dust capacity and oil carry-over on oil bath air cleaners. This test code…

ISO 13347-4:2004 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 the fan, which can be tested in accordance with ISO 13347-4:2004, are limited only by the practical…

This document defines key terms and parameters applied in the analysis of cognitive and visual-manual workload induced by transport information and control systems (TICS). It provides guidelines and minimum requirements on equipment and procedures for analysing cognitive and visual-manual load including assessment of TICS to: — plan evaluation trials; — specify (and install) data capture…

ISO/TS 11999-2:2015 describes compatibility for ensembles of firefighters personal protective equipment (PPE) to be used by firefighters, who are at risk of exposure to high levels of heat and/or flame while fighting fires occurring in structures. ISO/TS 11999-2:2015 includes methods for compatibility testing in laboratories and procedures for compatibility testing including the identification of…

This International Standard proposal specifies technical requirements and test method for temperature sensor in radiosonde. This International Standard is applicable to the temperature measurement traceable to SI unit in boom sensors according to variations of pressure and air speed under the simulated conditions of upper air. This proposed standard will mainly provide a) Terms and definitions…

This document specifies characteristics of fresh and dry baker’s yeast, particularly those relating to general product properties, application performance, physical and chemical properties, microbiology, and nutritional value information. This document is primarily intended for use by the baking industry, but is also aimed at laboratory and food testers

This part of ISO 7206 specifies a test method for determining short-term deformation of a press-fit acetabular component for total hip joint replacement under specific laboratory conditions. It also defines the conditions of testing so that the important parameters that affect the components are taken into account and it describes how the specimen is set up for testing. The described method is…

ISO 13347-2:2004 gives a detailed description of reverberant room methods for the determination of fan sound power levels. It is for use under standardized laboratory conditions and recognises that tests in situ are subject to increased uncertainty. These test procedures are not necessarily appropriate to site test conditions. Acoustic system effects are presently the subject of considerable…

ISO 13347:2004 deals with the determination of the acoustic performance of industrial fans. In addition, it may be used to determine the acoustic performance of fans combined with an ancillary device such as a roof cowl or damper or, where the fan is fitted with a silencer, the sound power resulting from the fan and silencer combination.
