Fine ceramics (advanced ceramics, advanced technical ceramics) — Test methods for fracture toughness of monolithic ceramics — Single-edge V-notch beam (SEVNB) method

ISO 23146:2012 specifies a method for the determination of the fracture toughness of advanced technical ceramics. The procedure makes use of single-edge V-notched bars, which are loaded in four-point bending until failure. It is applicable to monolithic ceramics with a grain size or major microstructural feature size larger than about 1 µm. The use of ISO 23146:2012 for yttria tetragonal zirconia polycrystal material (Y-TZP) is not recommended. The method might also be unsuitable for some other very tough or soft ceramics in which a sharp crack does not form at the root of the V-notch.

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.

Soil improvers and growing media - Determination of aqua regia soluble elements

This document specifies a method for the determination of elements in soil improvers or growing media extracts using inductively coupled plasmaatomic emission spectrometry (ICPAES) NOTE 1 Alternatively, other suitable analytical techniques, e.g. inductively coupled plasma mass spectrometry (ICPMS) or atomic absorption spectrometry (AAS), can be used for the measurement if the user proves that the method gives the same results. This method is applicable to aqua regia extracts prepared according to EN 13650:— 1. NOTE 2 The method may be used for the determination of other elements, provided the user has verified the applicability.

Sterile hypodermic syringes for single use - Part 1: Syringes for manual use (ISO/DIS 7886-1:2025)

ISO 7886-1:2017 specifies requirements and test methods for verifying the design of empty sterile single-use hypodermic syringes, with or without needle, made of plastic or other materials and intended for the aspiration and injection of fluids after filling by the end-users. This document does not provide requirements for lot release. The syringes are primarily for use in humans. Sterile syringes specified in this document are intended for use immediately after filling and are not intended to contain the medicament for extended periods of time. It excludes syringes for use with insulin (see ISO 8537), single-use syringes made of glass, syringes for use with power-driven syringe pumps, syringes pre-filled by the manufacturer, and syringes intended to be stored after filling (e.g. in a kit for filling by a pharmacist). Hypodermic syringes without a needle specified in this document are intended for use with hypodermic needles specified in ISO 7864.

Water quality - Uranium - Test method using alpha liquid scintillation counting (ISO/DIS 13169:2025)

This document specifies the measurement method for the determination of total activity concentration of uranium isotopes in non-saline waters by extraction and liquid scintillation counting. This method covers the measurement of soluble uranium isotopes in water in activity concentrations between approximately 2·10−3 Bq/kg and 10 Bq/kg when analysing a 1 l test sample volume with a 60 000 s counting time with a typical alpha LSC instrument. The ratio 234U/238U can also be determined. This method has not been tested for the measurement of other uranium isotopes.

Biological durability of wood and wood-based products - Quantitative determination of pentachlorophenol in wood - Gas chromatographic method

This document specifies a laboratory method of determining the pentachlorophenol content of wood. The method is applicable to all types of pentachlorophenol (PCP) in woods and wood-based materials as well as for the analysis of waste timber with respect to its pentachlorophenol (PCP) content. The method described has a measurement range from 250 µg/kg up to pentachlorophenol (PCP) contents of 5 mg/kg of dry matter. These figures refer to the given example (where an aliquot of 1 ml of the extract is used for acetylation, see 9.3). NOTE 1 If lower quantification limits are required, a higher volume of extract aliquot can be used for derivatisation. NOTE 2 This method could have some modifications with some wood species as hardwoods. In general, in the case of complex matrix, a method using mass spectrometry can be used.
