This document specifies methods for measuring the airborne noise emitted by small air-moving devices (AMDs), such as those used for cooling electronic, electrical, and mechanical equipment where the sound power level of the AMD is of interest.
Examples of these AMDs include propeller fans, tube-axial fans, vane-axial fans, centrifugal fans, motorized impellers, and their variations.
This document describes the test apparatus and methods for determining the airborne noise emitted by small AMDs as a function of the volume flow rate and the fan static pressure developed by the AMD on the test apparatus. It is intended for use by AMD manufacturers, by manufacturers who use AMDs for cooling electronic equipment and similar applications, and by testing laboratories. It provides a method for AMD manufacturers, equipment manufacturers and testing laboratories to obtain comparable results. Results of measurements made in accordance with this document are expected to be used for engineering information and performance verification, and the methods can be cited in purchase specifications and contracts between buyers and sellers. The ultimate purpose of the measurements is to provide data to assist the designers of electronic, electrical or mechanical equipment which contains one or more AMDs.
Based on experimental data, a method is given for calculating the maximum volume flow rate of the scaled plenum up to which this document is applicable.

This document specifies methods for the testing and rating of dampers and valves used in air distribution systems with pressure differences up to 2 000 Pa.
The tests incorporated in this document will address:
— leakage past a closed damper or valve (for classification see Annex C);
— casing leakage (for classification see Annex C);
— flow rate/pressure requirement characteristics;
— torque: (see Annex A);
— thermal transmittance: (see Annex B).
The acoustic testing of dampers and valves is not included in this document. The tests specified above apply to the following:
— measurement of leakage past a closed damper or valve;
— measurement of casing leakage;
— determination of flow rate and pressure requirements;
— measurement of torque characteristics (see Annex A);
— measurement of thermal transfer characteristics to determine insulation properties (see Annex B).
NOTE Certain aspects of the dynamic performance of dampers and/or valves are dependent upon the air distribution system to which they are connected and are, therefore, difficult to measure in isolation. Such considerations have led to the omission of these aspects of the dynamic performance measurements from this document. Also, in common with other air distribution components, the results from tests carried out in accordance with this document may not be directly applicable if the damper or valve is situated in an area of non-uniform flow.

This European Standard specifies the performance classification and test methods for materials used in chemical protective clothing, including gloves and footwear. The gloves and boots should have the same chemical protective barrier requirements as the fabric when an integral part of the clothing. This is a reference standard to which chemical protective clothing performance standards may refer in whole or in part, but this standard is not exhaustive in the sense that product standards may well require testing according to test method standards which are not included in this standard.
While these performance levels are intended to relate to the usage to which the chemical protective clothing is to be put, it is essential that the chemical protective clothing manufacturer or supplier indicate the intended use of the protective clothing and that the user (specifier) carries out a risk assessment in order to establish the correct performance level for the intended task.

This document specifies the requirements for cards and card interface devices used for identification. It takes into consideration both human and machine aspects and states minimum requirements.
It is the purpose of this document to provide criteria for the performance of cards. No consideration is given within this document to the amount of use, if any, experienced by the card prior to test.
NOTE 1 Numeric values in the SI and/or Imperial measurement system in this document have been rounded off and therefore are consistent with, but not exactly equal to, each other. Either system can be used, but intermixing or reconverting the two can result in errors. The original design was made using the Imperial measurement system.
NOTE 2 Thin flexible cards are not within the scope of this document (see the ISO/IEC 15457 series).

This Recommendation | International Standard supplements Rec. ITU-T X.509 | ISO/IEC 9594-8 and Rec. ITU-T X.510 | ISO/IEC 9594-11 by providing extended analysis of cryptographic algorithms and guidance in establishment and maintenance of a public-key infrastructure (PKI).
It is outside the scope of this Recommendation | International Standard to define new cryptographic algorithms, but it is within scope to discuss already-defined cryptographic algorithms that provide
optimal protection, including protection in the future with powerful quantum computers.
This Recommendation | International Standard specifies how public-key infrastructure (PKI) may be adapted to support machine-to-machine (M2M) communication, e.g., Smart grid and Internet of Things (IoT) to allow interworking.
This Recommendation | International Standard specifies the procedures for establishment and maintenance of a PKI supporting new areas, such as intelligent electricity net (smart grid), industrial internet of things.

This document specifies requirements and test methods for air-aspirated hand blowpipes.
This document applies to blowpipes for brazing, soldering, heating, fusion and other allied thermal processes, which use a fuel gas and aspirated air (injector-type blowpipes), and are intended for manual use.
This document is applicable to:
— air-aspirated hand blowpipes which are fed with a fuel gas in the gaseous phase, at a controlled pressure by a regulator, through a gas supply hose;
— air-aspirated hand blowpipes which are fed with a liquefied fuel gas in the gaseous phase at the container pressure, through a gas supply hose;
— so-called liquid-phase blowpipes which are fed with a fuel gas in the liquid phase, and where thermal evaporation takes place within the blowpipe.
It does not apply to blowpipes in which the fuel gas leaves the injector in the liquid phase, or to so-called “cartridge” blowpipes where the gas supply is fixed directly onto the blowpipe and possibly constitutes the shank.
NOTE Figures 1 to 4 of this document are given for guidance only, to facilitate the explanation of the terms.
They do not specify the construction details which are left to the discretion of the manufacturer.

This document specifies a formalism for the calculation of the illuminant metamerism of solid surface colours. It cannot be applied to colours of effect coatings without metrical adaptation.
This document only covers the phenomenon of metamerism for change of illuminant, which has the greatest meaning in practical application. In the case of chromaticity coordinates of a pair of samples under reference conditions that do not exactly match, recommendations are given on which correction measures are to be taken. Regarding the reproduction of colours, the metamerism index is used as a measure of quality in order to specify tolerances for colour differences between a colour sample and a colour match under different illumination conditions.
The quantification of the illuminant metamerism of pairs of samples is formally performed by a colour
difference assessment, for which tolerances that are common for the evaluation of residual colour differences can be used.
NOTE In the colorimetric literature and textbooks, the term geometric metamerism is sometimes used for the case that two colours appear to be the same under a specific geometry for visual assessment and selected
standard observer and standard illuminant pair, but is perceived as two different colours at changed observation geometry. The term geometric metamerism is different to metamerism described in this document.
