Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

Solid recovered fuels - Determination of moisture content using the oven dry method - Part 2: Determination of total moisture by a simplified method (ISO 21660-2:2025)
EN ISO 21660-2:2025

This document specifies a method for determination of the moisture content in a test portion of the laboratory sample by drying the test portion in an oven. This method is applicable for routine production control on site, e.g. if a high precision of the determination of moisture content is not required. It is applicable to all solid recovered fuels.
If the solid recovered fuel contains large amounts of oil-fractions, a lower temperature is advisable (e.g. 50 °C ± 10 °C) and a longer drying time until constant mass is achieved. As an alternative, the Karl-Fischer-Titration-Method (see ISO 760[1]) is advisable.
NOTE 1        The total moisture content of recovered fuels is not an absolute value and therefore standardised conditions for its determination are indispensable to enable comparative determinations.
NOTE 2        The term moisture content when used with recovered materials can be misleading since solid recovered materials, e.g. biomass, frequently contain varying amounts of volatile compounds (extractives) which can evaporate when determining the moisture content of the general analyses sample by oven drying.

Glass in building - Determination of thermal transmittance (U value) - Calculation method
EN 673:2024

This document specifies a calculation method to determine the thermal transmittance of glass with flat and parallel surfaces.
This document applies to uncoated glass (including glass with structured surfaces, e.g. patterned glass), coated glass and materials not transparent in the far infrared which is the case for soda lime glass products, borosilicate glass, glass ceramic, alkaline earth silicate glass and alumino silicate glass. It applies also to multiple glazing comprising such glasses and/or materials. It does not apply to multiple glazing which include in the gas space sheets or foils that are far infrared transparent.
The procedure specified in this document determines the U value (thermal transmittance) in the central area of glazing.
The edge effects due to the thermal bridge through the spacer of an insulating glass unit or through the window frame are not included. Furthermore, energy transfer due to solar radiation is not taken into account. The effects of Georgian and other bars are excluded from the scope of this document.
NOTE   EN ISO 10077 1:2017 provides a methodology for calculating the overall U value of windows, doors and shutters [1], taking account of the U value calculated for the glass components according to this document.
Also excluded from the calculation methodology are any effects due to gases that absorb infrared radiation in the 5 to 50 µm range.
The primary purpose of this document is product comparison, for which a vertical position of the glazing is specified. In addition, U values are calculated using the same procedure for other purposes, in particular for predicting:
-   heat loss through glass;
-   conduction heat gains in summer;
-   condensation on glass surfaces;
-   the effect of the absorbed solar radiation in determining the solar factor [2].
Reference can be made to [3], [4] and [5] or other European Standards dealing with heat loss calculations for the application of glazing U values determined by this standard.
Reference can be made to [6] for detailed calculations of U values of glazing, including shading devices.
Vacuum Insulating Glass (VIG) is excluded from the scope of this document. For determination of the U value of VIG, please refer to EN 674 or ISO 19916-1.
A procedure for the determination of emissivity is given in EN 12898.
The rules have been made as simple as possible consistent with accuracy.

Non-destructive testing - Characteristics of focal spots in industrial X-ray systems - Part 1: Pinhole camera radiographic method (ISO 32543-1:2024)
EN ISO 32543-1:2025

This document specifies a method for the measurement of effective focal spot dimensions above 0,1 mm of X-ray systems up to and including 1 000 kV X-ray voltage by means of the pinhole camera method with digital evaluation. The tube voltage applied for this measurement is restricted to 200 kV for visual film evaluation and can be selected higher than 200 kV if digital detectors are used.
The imaging quality and the resolution of X-ray images depend highly on the characteristics of the effective focal spot, in particular the size and the two-dimensional intensity distribution as seen from the detector plane. Compared to the other methods specified in the EN 12543 series and the ISO 32543 series, this method allows to obtain an image of the focal spot and to see the state of it (e.g. cratering of the anode).
This test method provides instructions for determining the effective size (dimensions) of standard (macro focal spots) and mini focal spots of industrial X-ray tubes. This determination is based on the measurement of an image of a focal spot that has been radiographically recorded with a “pinhole” technique and evaluated with a digital method.
For the characterization of commercial X-ray tube types (i.e. for advertising or trade), the specific FS (focal spot) values of Annex A can be used.
