1.1 This International Standard specifies requirements for instruments and test procedures for the measurement and reporting of sound pressure levels at crew and passenger locations in the interior of aircraft under steady flight conditions. The sound pressure levels may be used to determine various quantities for describing the acoustical environment in the interior of the aircraft. The…

This International Standard specifies the characteristics of 40 mm drawbar eyes, necessary for the interchangeability of the coupling components on trailers and permitting interchangeability between towing vehicles and trailers equipped with these components. This International Standard is applicable to mechanical connections designed for commercial vehicles and trailers, the maximum total mass…

This International Standard specifies a method for the determination of the trypsin inhibitor activity (TIA) of soya products. This trypsin inhibitor activity is indicative of the degree of toasting of these products. The detection limit of the method is 0,5 mg/g.

This International Standard specifies a method for the determination of the mass loss of rigid cellular plastics as a result of a combination of abrasion and impact produced by a laboratory tumbling mechanism.

This International Standard provides tables which enable the transliteration into Latin characters from text in Indic scripts which are largely specified in rows 09 to 0D of UCS (ISO/IEC 10646-1 and Unicode). The tables provide for the Devanagari, Bengali (including the characters used for writing Assamese), Gujarati, Gurmukhi, Kannada, Malayalam, Oriya, Sinhala, Tamil, and Telugu scripts which…

This International Standard defines a common set of reporting parameters and describes the methods to be used in the determination and presentation of individual densitometer performance and manufacturer-reported performance specifications. This International Standard applies to transmission and reflection densitometers typically manufactured for and used by the photographic, graphic arts and…

This International Standard specifies a method for the determination of the ash content of petroleum products, such as distillate and residual fuel oils, crude petroleum, lubricating oils, waxes and other petroleum products, in which any ash-forming constituents present are normally considered to be undesirable impurities or contaminants. Ash can result from oil-soluble or water-soluble metallic…

This International Standard specifies test methods and minimum performance requirements for protective clothing that relies upon the ability of the outer material to reflect intense radiant heat. The clothing covered by this International Standard is intended to provide protection against flame lick and intense radiant heat and it should be worn for short periods only. Subject to a risk…

This International Standard describes a machine coordinate system related to the primary motions of individual numerically controlled machines and the associated machine motions. The machine coordinate system is used to provide the coordinates of a moving tool (or a point in the working space or on the drawing) with respect to a stationary workpiece. Thus a programmer can describe the machine…

This National Standard of Canada is based on International Standard CEI/IEC 61112: 1992 (first edition, 1992-12) including Corrigendum (dated May 2000). 1. Scope This International Standard is applicable to insulating blankets for the protection of workers from accidental contact with live or earthed electrical conductors, apparatus or circuits and avoidance of short circuits on a.c. and d…
