Information processing — Representation of numerical values in character strings for information int...
Provides three presentations of numerical values represented in character strings readable by machine for use in interchange between data processing systems. Gives guidance for development programming language standards and implementation programming products. These representations are recognizable by humans. Standard applies only to numerical values consisting of a finite number of digits with…

Water quality — Determination of free chlorine and total chlorine — Part 2: Colorimetric method usin...
Specifies a procedure for water, readily applicable to field testing; it is based on measurement of the colour intensity by visual comparison of the colour with a scale of standards which is regularly calibrated. Sea water and waters containing bromides and iodides comprise a group for which special procedures are required. The procedure is applicable to concentrations, in terms of chlorine, from…
Textiles — Tests for colour fastness — Part F: Standard adjacent fabrics
The specifications included in ISO 105/F are intended to establish undyed adjacent fabrics from different single fibres which may be used for the assessment of staining in colour fastness test procedure. These single-fibre adjacent fabrics exhibit standardized staining properties. The parts of ISO 105/F provide single-fibre adjacent fabrics as follows: F01: Wool; F02: Cotton and viscose; F03:…
Atmospheres for conditioning and testing — Determination of relative humidity — Part 2: Whirling psy...
The method specified applies for temperatures within the range from 5 to 80 °C. The property is determined with an uncertainty not exceeding 3 % r. h. The method is restricted to wet-bulb temperatures not lower than 1 C, dry-bulb temperatures not higher than 80 °C, and pressures not differing from standard atmospheric pressure by more than 30 %.
The purpose of the measuring method is to determine the residual camber height and length as a function of the load ("flattening test"). Gives some essential informations related to the parameters "contact load" and "standard camber length". Applies to cross-country skis of size 130 cm and longer.
Specifies a method for estimating the water distribution in relation to a grading scale which is enclosed to the standard. The water dispersion value of butter is used for grading purposes because the size and distribution of the water droplets is applicable to all types of butter. The sampling shall be made in accordance with ISO 707.
Data communication — Arrangements for DTE to DTE physical connection using V.24 and X.24 interchange...
Describes various arrangements for interconnection of Data Terminal Equipment (DTE), without intermediate Data Circuit-terminating Equipment, concerning electrical, mechanical, and functional characteristics. Applies to DTEs with interface circuits standardized in CCITT Recommendation V.24 for data transmission over telephone networks or with interface circuits standardized in CCITT…
