Water quality - Enumeration of Escherichia coli and coliform bacteria - Part 2: Most probable number method (ISO/DIS 9308-2:2026)

This document specifies a method for the enumeration of E. coli and coliform bacteria in water. The method is based on the growth of target organisms in a liquid medium and calculation of the “Most Probable Number” (MPN) of organisms by reference to MPN tables or by use of appropriate formulae 1]. This method can be applied to a range of types of water (for example drinking water, groundwater, surface water, recreational water and wastewater),[2-5] including those containing a considerable amount of suspended matter and high background counts of heterotrophic bacteria. Users should satisfy themselves that any product used has been validated for its intended use (e.g. chlorinated drinking water) and should generate performance characteristics using ISO13843.[6] Performance characteristic data generated prior to 2017 using ISO TR 13843[7] is also acceptable. If a water sample has some background colour, the incubated sample should be compared to a blank control of the same water sample This method relies upon the detection of E. coli based upon expression of the enzyme β‑D‑glucuronidase and consequently does not detect some enteropathogenic strains of E. coli, which do not typically express this enzyme. Additionally, there are a small number of other E. coli strains that do not express β‑D‑glucuronidase. As they are β‑D‑galactosidase positive, they will appear as coliform bacteria.

Inorganic fertilizers - Determination of specific parameters

This document specifies a reference to the method for the determination of the following specific parameters in inorganic fertilizers: — granulometry; — organic carbon content; — dry matter content. This document is applicable to the fertilizing products blends where a blend is a mix of at least two of the following components: fertilizers, liming materials, soil improvers, growing media, inhibitors, plant biostimulants, and where the following category: inorganic fertilizers is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If inorganic fertilizer is not the highest % in the blend, the European Standard for the highest % of the blend applies. In case a fertilizing product blend is composed of components in equal quantity, the user decides which standard to apply. Variations in analytical methods for fertilizing product blends can lead to differing results as some components or matrix interactions can affect the outcome. Validation procedures have shown that developed standard methods are robust and reliable across diverse product compositions, but possible interferences and unexpected results when analysing fertilizing product blends are possible.

Electrical requirements for lifts, escalators and moving walks - Part 20: Cybersecurity (ISO/DIS 8102-20:2026)

This document specifies cybersecurity requirements for new lifts, escalators and moving walks, referred to in this document as “equipment under control (EUC)”, designed in accordance with the ISO 8100 series. It is also applicable with other lift, escalator and moving walk standards that specify similar requirements, and to other lift-related equipment connected to the EUC. This document specifies product and system requirements related to cybersecurity threats in the following lifecycle steps: — product development (process and product requirements); — manufacturing; — installation; — operation and maintenance; — decommissioning. This document addresses the roles of product supplier and system integrator as shown in IEC 62443-4-1:2018, Figure 2, for the EUC. This document does not address the role of asset owner as shown in IEC 62443-4-1:2018, Figure 2, but defines requirements for the product supplier and system integrator of the EUC to establish documentation allowing the asset owner, referred to as the “EUC owner” in this document, to achieve and maintain the security of the EUC. This document specifies the minimum cybersecurity requirements for: — essential functions; — safety functions; — alarm functions. This document is applicable to EUCs that are capable of connectivity to external systems such as building networks, cloud services, or service tools. The capability to connectivity can exist through equipment permanently available on site, or equipment temporarily brought to the location during the installation, operation and maintenance, or decommissioning steps. EUC interfaces to external systems and services are in the scope of this document. External systems and services as such are out of the scope of this document. This document does not apply to EUC that are installed before the date of its publication.

Petroleum products - Determination of boiling range distribution - Gas chromatography method (ISO/DIS 3924:2026)

This document specifies a method for the determination of the boiling range distribution of petroleum products. The method is applicable to petroleum products and fractions with a final boiling point of 538 °C or lower at atmospheric pressure as determined by this document. This document does not apply to gasoline samples or gasoline components. The method is limited to products having a boiling range greater than 55 °C and having a vapour pressure sufficiently low to permit sampling at ambient temperature. The document describes two procedures. a) Procedure A allows a larger selection of columns and analysis conditions, such as packed and capillary columns as well as a thermal conductivity detector in addition to the flame ionization detector. Analysis times range from 14 min to 60 min. b) Procedure B is restricted to only three capillary columns and requires no sample dilution. The analysis time is reduced to about 8 min. Both procedures have been successfully applied to samples containing fatty acid methyl esters (FAME) up to 20 % (volume fraction). NOTE For the purposes of this document, the terms "% (mass fraction)" and "% (volume fraction)" are used to represent the mass fraction (µ), the volume fraction (φ) of a material.

Chemical disinfectants - Quantitative suspension test for the evaluation of sporicidal activity of chemical disinfectants used in food, industrial, domestic and institutional areas - Test method and requirements (phase 2, step 1)

This document specifies a test method (phase 2/step 1) and the minimum requirements for sporicidal activity of chemical disinfectant products that form a homogeneous, physically stable preparation in hard water and that are used in food, industrial, domestic and institutional areas, excluding areas and situations where disinfection is medically indicated and excluding products used on living tissues except those for hand hygiene in the above considered areas. This European Standard applies at least to the following: a) processing, distribution and retailing of: 1) food of animal origin: - milk and milk products; - meat and meat products; - fish, seafood, and related products; - eggs and egg products; - animal feeds; - etc.; 2) food of vegetable origin: - beverages; - fruits, vegetables and derivatives (including sugar, distillery, etc.); - flour, milling and baking; - animal feeds; - etc.; b) institutional and domestic areas: - catering establishments; - public areas; - public transports; - schools; - nurseries; - shops; - sports rooms; - waste containers (bins, etc.); - hotels; - dwellings; - clinically non sensitive areas of hospitals; - offices; - etc.; c) other industrial areas: - packaging material; - biotechnology (yeast, proteins, enzymes, etc.); - pharmaceutical; - cosmetics and toiletries; - textiles; - space industry, computer industry; - etc. Using this European Standard, it is not possible to determine the sporicidal activity of undiluted product as some dilution is always produced by adding the inoculum and interfering substance. Products can only be tested at a concentration of 80 % or less. NOTE The method described is intended to determine the activity of commercial formulations or active substances on spores in the conditions in which they are used.
