International Electrotechnical Vocabulary (IEV) - Part 881: Radiology and radiological physics
Replaces IEC 60050(65) (1964). It has the status of a horizontal standard in accordance with <a href="https://webstore.iec.ch/advsearchform?&RefNbr=108&typepub=GUIDE">IEC Guide 108</a>.
Technical drawings — Requirements for microcopying
The rules of ISO 128, ISO 3098, ISO 5457 are expanded. The requirements will provide for high quality microforms with which legible enlargement copies can be made, and documents complying with them can also be reproduced by any other reprographic system. It is recommended that all drawing office documents be executed in accordance with this International Standard.
The terms and defintions given in this International Standard have been confined to those parts of the spinning machine which are specific to open-end yarn production technology. Terms and definitions which relate to machine parts for which definitions appear elsewhere, for example in ISO 477 and ISO 2205, are not included.
Acetic anhydride for industrial use — Methods of test
Gives general instructions and specifies methods of analysis. The methods to be used are determination of destillation yield, of bromine number, of arsenic content, of permanganate index, of dichromate index, the measurement of colour, titrimetric determination of acetic anhydride content, gravimetric determination of ash, spectrometric determination of phosphate content and visual limit tests…
Power sources for manual metal arc welding with covered electrodes and for the TIG process
Specifies the information to appear on the rating plate and describes test methods to verify the compliance of the power source with this International Standard. Applies to the types of power sources most commonly used in industrial applications for manual metal arc welding with covered electrodes and for the TIG process, except for oil-cooled power sources.
Gives general instructions and specifies methods od analysis. The methods to be used are determination of density at 20 °C, determination ofdry residue after evaporation on a water bath, measurement of colour, determination of distillation yield, determination of water content, detection of the alkalinity or acidity to phenolphthalein, spectrometric detection of content of carbonyl compounds in…
