ISO 2173:2003 specifies a refractometric method for the determination of the soluble solids in fruit and vegetable products. This method is particularly applicable to thick products, to products containing suspended matter, and to products rich in sugar. If the products contain other dissolved substances, the results will be only approximate; nevertheless, for convenience the result obtained by…

This part of CISPR 16 is designated a basic standard, which specifies the characteristics and performance of equipment for the measurement of radio disturbance voltages and currents in the frequency range 9 kHz to 1 GHz. Specifications for ancillary apparatus are included for: artificial mains networks, current and voltage probes and coupling units for current injection on cables. The…

ISO 14172:2003 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.

Gives the requirements for industrial rigid laminated sheets for electrical purposes based on phenolic resin and different reinforcements. Applications and distinguishing properties are given. Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application should be based on the actual requirements…

ISO/TR 13425:2003 gives guidance on the selection and an overview of all the referenced standards, guides, technical reports and DIS developed by ISO/TC 69 from a user prospective. DIS are drafts which can be amended. Both categories are documents, which are available to the public. ISO/TR 13425:2003 also gives two descriptions of the content of the standards by two sets of abstracts: non-…

ISO 589:2003 describes two methods for the determination of the total moisture content of hard coals. Depending on the coal rank, there may be systematic differences between the results obtained by applying different methods on subsamples of the same sample. Methods using a nitrogen atmosphere are suitable for all hard coals; methods with drying in air are only suitable for hard coals not…

ISO 762:2003 specifies a method for the determination of the mineral impurities content (impurities generally originating from the soil) of fruit and vegetable products.

Specifies requirements for gas-insulated, metal-enclosed switchgear in which the insulation is obtained, at least partly, by an insulating gas other than air at atmospheric pressure, for alternating current of rated voltages above 52 kV, for indoor and outdoor installation, and for service frequencies up to and including 60 Hz. For the purpose of this standard, the terms "GIS" and…

Contains specific requirements for the construction and testing of electrical apparatus with the type of protection flameproof enclosure "d", intended for use in explosive gas atmospheres. The contents of the corrigendum of February 2007 have been included in this copy.
