Energy performance of buildings - Method for calculation of system energy requirements and system efficiencies - Part 7-1: DHW instantaneous heat recovery- Module M8-13

This calculation module applies to instantaneous domestic hot water heat recovery using a counter-flow heat exchanger between the drain water and the incoming domestic cold water. This module calculates the recovered heat, to be taken into account in the overall calculation procedure of the energy performance of the building. The scope of this document is to standardize the: - required inputs; - calculation methods; - required outputs; of the instantaneous heat recovery from domestic hot water drains. This document provides a calculation method for one calculation interval. This calculation is intended to be connected to the whole building calculation model and takes into account the external conditions and system controls that may influence the instantaneous heat recovery from domestic hot water drains. This document does not apply to storage heat recovery or the use of drain water as a source for heat pumps. This document does not apply to sizing or inspection of domestic hot water heat recovery devices. Table 1 shows the relative position of this document within the set of EPB standards in the context of the modular structure as set out in EN ISO 52000-1. NOTE 1 The same Table is found in CEN ISO/TR 52000-2, with, for each module, the numbers of the relevant EPB standards and accompanying technical reports that are published or in preparation. NOTE 2 The modules represent EPB standards, although one EPB standard might cover more than one module and one module might be covered by more than one EPB standard, for instance a simplified and a detailed method respectively. See also Clause 2 and Table A.1 and Table B.1.

Water quality - Enumeration of Escherichia coli and coliform bacteria - Part 4: Membrane filtration method for Escherichia coli in water with high levels of background bacteria (ISO/DIS 9308-4:2025)

This document describes a highly specific method for the enumeration of Escherichia coli (E. coli) in water. The method is based on membrane filtration followed by culture at 44 °C on chromogenic agar medium containing an ingredient for the detection of the enzyme β-glucuronidase, and calculation of the number of target organisms in the sample[5,6,13]. Because of the high specificity of the method, this document is suitable for waters with high levels of background bacteria, such as surface waters including bathing water and wastewater provided that they contain little particulate or colloidal matter relative to the E. coli concentration. The method can be used for fresh water and, with an adaptation, for marine water. E. coli strains which do not grow at 44 °C and those that are β-glucuronidase negative, such as E. coli O157, will not be detected as E. coli by this method. This method is not applicable to the enumeration and detection of coliform bacteria other than E. coli.

Compost and digestate - Determination of polycyclic aromatic hydrocarbons (PAH) by gas chromatography (GC) and high performance liquid chromatography (HPLC)

This document specifies different methods for quantitative determination of 16 polycyclic aromatic hydrocarbons (PAH) (see Table 1) in compost or digestate, using GC-MS, GCMS/MS or HPLC UV DAD/FLD covering a wide range of PAH contamination levels (see Table 1). When using fluorescence detection, acenaphthylene cannot be measured. Table 1 — Target analytes of this document [...table not reproduced...] The limit of detection depends on the determinants, the equipment used, the quality of chemicals used for the extraction of the sample and the clean-up of the extract. This document contains decision tables based on the properties of the sample and the extraction and clean-up procedure to be used. The method may be applied to the analysis of other PAH not specified in the scope, provided suitability is proven by proper in-house validation experiments.

Cleanrooms and associated controlled environments - Part 13: Cleaning of surfaces to achieve defined levels of cleanliness in terms of particle and chemical concentration (ISO/FDIS 14644-13:2025)

ISO 14644-13:2017 gives guidelines for cleaning to a specified degree on cleanroom surfaces, surfaces of equipment in a cleanroom and surfaces of materials in a cleanroom. Under consideration are all surfaces (external or internal) that are of interest. It provides guidance on the assessment of cleaning methods for achieving the required surface cleanliness by particle concentration (SCP) and surface cleanliness by chemical concentration (SCC) classes and which techniques should be considered to achieve these specified levels. The appropriateness of cleaning techniques will make reference to the cleanliness classes and associated test methods found in ISO 14644‑9 and ISO 14644‑10. The following matters of general guidance will be provided: - expected surface cleanliness levels; - suitability of cleaning methods; - compatibility of surfaces with the cleaning technique; - assessment of cleaning appropriateness. The following will be excluded from this document: - classification of cleaning methods; - product produced within a cleanroom; - specific surface-related cleaning methods; - detailed description of cleaning mechanisms, methods and procedures of various cleaning methods; - detailed material characteristics; - description of damage mechanisms by cleaning processes and time-dependent effects; - references to interactive bonding forces between contaminants and surfaces or generation processes that are usually time-dependent and process-dependent; - other characteristics of particles such as electrostatic charge, ionic charges, etc.; - chemical reactions between molecular contaminants and surfaces; - microbiological aspects of surface cleanliness; - radioactive aspects of contamination; - health and safety considerations; - environmental aspects such as waste disposal, emissions, etc.; - selection and use of statistical methods.
