ISO 589:2008 describes two methods for determination of the total moisture content of hard coals, a two-stage method and a single-stage method. For either method there is a choice between drying in air and drying in a nitrogen atmosphere. Depending on the coal rank, there may be systematic differences between the results obtained by drying in the different atmospheres on subsamples of a sample.…

ISO 29771:2008 specifies the equipment and procedures for determining the organic content of thermal insulating materials. The method is aimed at determining the organic content for products that are inorganic, i.e. products containing a low percentage of organic compounds, either unfaced products or the insulating material of a faced product. ISO 29771:2008 is not applicable for the…

ISO 16634-1:2008 specifies a method for the determination of the total nitrogen content and the calculation of crude protein content of oilseeds and animal feeding stuffs. This method, like the Kjeldahl method, does not distinguish between protein nitrogen and non-protein nitrogen. For the calculation of protein content, various conversion factors are used. This method is not applicable to milk…

ISO/IEC 14496-12:2008 specifies the ISO base media file format, which is a general format forming the basis for a number of other more specific file formats. This format contains the timing, structure, and media information for timed sequences of media data, such as audio/visual presentations. ISO/IEC 14496-12:2008 is applicable to MPEG-4, but its technical content is identical to that of ISO/IEC…

IEC 80601-2-59:2008 applies to the basic safety and essential performance of screening thermographs intended to be used for the individual non-invasive febrile temperature screening of humans under indoor environmental conditions. IEC 80601-2-59:2008 sets laboratory characterization test limits for the screening thermograph. The contents of the corrigendum of April 2009 have been included in this…

IEC 62059-31-1:2008 provides one of several possible methods for estimating product life characteristics by accelerated reliability testing. In this standard, elevated, constant temperature and humidity is applied to achieve acceleration. The method takes into account the effect of voltage and current variation. It is applicable to all types of metering equipment for energy measurement, tariff…

IEC 62087:2008(E) specifies methods of measurement for the power consumption of television sets, video recording equipment, Set Top Boxes (STBs), audio equipment and multi-function equipment for consumer use. Television sets include, but are not limited to, those with CRT, LCD, PDP or projection technologies. This second edition cancels and replaces the first edition, published in 2002 and…

ISO 14172:2008 prescribes requirements for the classification of nickel- and nickel-alloy-covered electrodes for manual metal arc welding and overlaying. It includes those compositions in which the nickel content exceeds that of any other element.

IEC 61298-4:2008 specifies general methods and procedures for conducting tests, and reporting on the functional and performance characteristics of process measurement and control devices. The tests are applicable to any such devices characterized by their own specific input and output variables, and by the specific relationship (transfer function) between the inputs and outputs, and include…
