This International Standard describes how International Standards concerned with the ergonomics of the physical environment can be applied for people with special requirements, who would otherwise be considered to be beyond the scope of those standards. It has been produced according to the principles of accessible design provided in ISO/IEC Guide 71 and using the data provided in ISO/TR 22411.…

This International Standard specifies the characteristics of hot-rolled twin-roll cast carbon steel sheet of commercial quality produced by the twin-roll cast process. Hot-rolled twin-roll cast steel sheet is suitable for many applications where the presence of oxide or scale or normal surface imperfections disclosed after removal of oxide or scale, are not objectionable. It is not suitable for…

This International Standard specifies the characteristics of hot-rolled twin-roll cast steel sheet of structural quality and high strength steel. The product is intended for applications where specific mechanical properties are required. It is generally used in the delivered condition and is intended for bolted, riveted or welded structures. This product is produced on a wide strip mill, not a…

This International Standard specifies the characteristics of continuous hot-dip zinc-coated twin-roll cast steel sheet of commercial quality manufactured using the twin-roll cast steel-making process. The product is intended for applications where resistance to corrosion is of prime importance. The steel sheet is produced in a number of coating mass, surface treatments and ordering conditions.

This International Standard specifies the characteristics of continuous hot-dip zinc-coated twin-roll cast steel sheet products of structural quality and high strength steel. The product is intended for applications where resistance to corrosion is of prime importance. The steel sheet is produced in a number of grades, coating mass, ordering conditions and surface treatments.

This International Standard provides an environmental survey method for the assessment of the comfort and well-being of occupants of indoor and outdoor environments. It is not restricted to any particular environment, but provides the general principles that allow assessment and evaluation. It presents the principles for conducting an environmental survey to assess the comfort and well-being of…

This International Standard specifies test methods for determining the physical properties of synchronous belts used in driving engine parts, such as camshafts, fuel injection pumps, balancing shafts. These test methods are intended to provide a means of characterizing synchronous belt properties for belts which are evaluated and qualified by dynamic laboratory and field testing. NOTE The…

This International Standard specifies a method for the determination of lethal as well as sublethal effects of contaminated sediments on the ostracod crustacean Heterocypris incongruens after 6 d exposure. The method is applicable not only to fresh water sediments, but also by extension to solid wastes and soils after addition of (uncontaminated) water. The method can also be applied to…

This International Standard provides procedures for electron microprobe elemental-mapping analysis using wavelength-dispersive spectrometry. The choice between mapping with the electron beam moving digitally across the specimen (electron beam mapping) and mapping with stage movement only (large-area mapping) is assessed. It describes five types of data processing: the raw X‑ray intensity data…
