This document specifies a procedure for determining the emissivity at room temperature of the surfaces of glass and coated glass. The emissivity is necessary for taking into account heat transfer by radiation from surfaces at the standard temperature of 283 K in the determination of the U value and of the total solar transmittance of glazing according to REF [5] \r \h ISO 9050[5] 08D0C9EA79F9BACE118C8200AA004BA90B0200000008000000040000005B0035005D000000 , REF [6] \r \h ISO 10291[6] 08D0C9EA79F9BACE118C8200AA004BA90B0200000008000000040000005B0036005D000000 , REF [7] \r \h ISO 10292[7] 08D0C9EA79F9BACE118C8200AA004BA90B0200000008000000040000005B0037005D000000 , and REF [8] \r \h ISO 10293[8] 08D0C9EA79F9BACE118C8200AA004BA90B0200000008000000040000005B0038005D000000 . The procedure, being based on spectrophotometric specular reflectance measurements at near normal incidence on materials that are non-transparent in the infrared region, is not applicable to glazing components with at least one of the following characteristics: a) with rough or structured surfaces where the incident radiation is diffusely reflected; b) with curved surfaces where the incident radiation is regularly reflected at angles unsuitable to reach the detector while using specular reflectance accessories; c) infrared transparent. However, it can be applied with caution to any glazing component provided its surfaces are flat and non-diffusing (see non-diffusing glazing component) and it is non-transparent in the infrared region (see glazing component non-transparent in the infrared region). Although transmittance measurements are included in this document, they are only necessary to check if the specimen is non-transparent in the infrared region in the context of this document (see glazing component non-transparent in the infrared region). If the specimen is transparent in the infrared region, this document is not applicable.

It is applicable for use in its entirety to the extent specified for a product acceptance test, rather than merely a means of assessing performance in service of pressurized water reactor.

This document specifies methods for the calculation of the dry matter fraction of sludge, sludge products, treated biowaste, soil and waste for which the results of performed analysis are calculated to the dry matter basis. Depending on the nature and origin of the sample, the calculation is based on a determination of the dry residue (method A) or a determination of the water content (methods A and B). It applies to samples containing more than 1 % (mass fraction) of dry residue or more than 1 % (mass fraction) of water. Method A applies to sludge, sludge products, treated biowaste, soil and solid waste. Method B applies to liquid waste and to samples which are suspected or known to contain volatiles except for water.

Test XD3 is intended to determine the resistance of electronic assemblies suitable for cleaning processes to the various cleaning processes to which they are exposed during manufacturing, including the effects of assembly and soldering processes.

This document establishes ergonomic design principles for interactive systems related to the software-controlled presentation of information by user interfaces. It applies to the three main modalities (visual, auditory, tactile or haptic) typically used in information and communication technology (ICT). These principles apply to the perception and understanding of presented information. These principles are applicable in the analysis, design and evaluation of interactive systems. This document also provides recommendations corresponding to the principles. The recommendations for each of the principles are not exhaustive and are not necessarily independent from one another.
While this document is applicable to all types of interactive systems, it does not cover the specifics of particular application domains which require context-specific recommendations. This document also applies to outputs from interactive systems (such as printed documents and document exports in common computer formats, e.g. pdf, text and tabular formats).
