Gives standards on the following sub-categories of analogue integrated circuits: -operational amplifiers (having two inputs and one output); -audio-amplifiers, video-amplifiers and multichannel amplifiers for telecommunications; -R.F. and I.F. amplifiers; -voltage and current regulators; -analogue signal switching circuits. Should be used with IEC 60747-1 and 60748-1.
Cranes — Overhead travelling cranes and portal bridge cranes — Tolerances for cranes and tracks
Specifies the manufacturing tolerances at standard temperature of 20 °C. These tolerances apply to a lifting appliance loaded solely by ist own mass. Tolerances take no account of elastic deformation during operation.
Oils of sassafras and nutmeg — Determination of safrole and cis- and trans-isosafrole content — Gas ...
A small quantity of the oils is analyzed by gas chromatography under specified conditions on a packed column. The safrole and cis- and trans-isosafrole contents are determined by using the internal standard method. As stationary phase are used polydimethylsiloxane, or polyethylene glycol 20000. Operating temperatures: Oven: isotherm about 100 °C when using polydimethylsiloxane; isotherm about 125…
Oils of thujone-containing Artemisia and oil of sage (Salvia officinalis Linnaeus) — Determination o...
A small quantity of the oils is analyzed under specified conditions. The alpha- and beta-thujone contents are determined by using the internal standard or addition method. As stationary phase are used cyanopropyl methylphenyl methyl silicone, or trifluoropropylmethyl silicone, or polyethylene glycol 1500. Operating temperatures: Oven: isotherm about 100 °C when using cyanopropyl methylphenyl…
Oil of calamus — Determination of cis-beta-asarone content — Gas chromatographic method on packed co...
A small quantity of the oil is analyzed under specified conditions. The cis-beta-asarone contents is determined by using the internal standard or addition method. As stationary phase polyethylene glycol 20000 is used. Operating temperatures: Oven: isotherm about 190 °C. Injection system and detector: about 170 °C.
Specifies a method of test and criteria for vertical and horizontal ducts under standardized fire conditions. The general purpose is to measure the ability to resist the spread of fire from one fire compartment to another without the aid of fire dampers. Is applicable to vertical and horizontal ducts with or without branches, taking into account joints, air supply and exhaust openings and…
Cereals and cereal products — Determination of moisture content (Basic reference method)
The method is not applicable to maize, for which an identical method is specified in the annex to ISO 6540. The method is idended to serve as a standard for checking and perfecting routine methods. It consists in , if necessary, grinding of a sample, after conditioning, if required, drying of a test portion under reduced pressure, at a temperatur between 45 and 50 C and in the presence of a…
Methods of test for full-flow lubricating oil filters for internal combustion engines — Part 6: Stat...
Establishes standard test procedures for measuring the performance of filters. It does not apply to filters for use in aeronautical applications. Includes the report of test results. Describes test rig and test liquid.
