Pigments and extenders - Dispersion procedure for sedimentation-based particle sizing of suspended pigment or extender with liquid sedimentation methods (ISO/DIS 20427:2025)

This document specifies sample preparation methods to determine the size distribution of separate particles of a single pigment or extender, which is dispersed in a liquid by application of a standardized dispersion procedure, using an ultrasonic device, shaker device or wet jet mill. The sample preparation methods described are optimized for measurements carried out with a particle sizing technique based on sedimentation. This technique relies on particle migration due to gravitation or centrifugal forces and requires a density contrast between the particles and the liquid phase.

Animal and vegetable fats and oils - Gas chromatography of fatty acid methyl esters - Part 4: Determination by capillary gas chromatography (ISO/DIS 12966-4:2025)

This part of ISO 12966 specifies a method for the determination of fatty acid methyl esters (FAMEs) derived by transesterification or esterification from fats, oils, and fatty acids by capillary gas chromatography (GLC). Fatty acid methyl esters from C4 to C24 can be separated using this part of ISO 12966 including saturated fatty acid methyl esters, cis- and trans-monounsaturated fatty acid methyl esters, and cis- and trans-polyunsaturated fatty acid methyl esters. The method is applicable to crude, refined, partially hydrogenated, or fully hydrogenated fats, oils, and fatty acids derived from animal and vegetable sources, and fats extracted from foodstuff. Milk and milk products (or fat coming from milk and milk products) are excluded from the scope of this part of ISO 12966. This part of ISO 12966 is not applicable to di-, tri-, polymerized and oxidized fatty acids, and fats and oils. A method for the determination of the composition of fatty acid methyl esters expressed by area % in liquid vegetable oils is proposed in Annex E.

Aerospace series - Cables, electrical, aircraft use - Test methods - Part 701: Strippability and adherence of insulation to the conductor

This document specifies methods of measuring the strippability and adherence of the insulation to a conductor of a finished cable. When a particular method is not specified in the detail product specification, method A is the default test method. Method B is suitable for wires insulated with materials showing a low adhesion to the conductor due to the poor repeatability of the test method A with this type of wires. It is intended to be used together with EN 3475 100.

Portable fire extinguishers - Part 7: Characteristics, performance requirements and test methods

This document specifies the characteristics, performance requirements and test methods for portable fire extinguishers. Reference to the suitability of an extinguisher for use on gaseous fires (Class C fires) are at the manufacturer’s discretion but are applied only to powder type extinguishers which have gained a Class B or Class A and Class B rating. Suitability of extinguishers for use on Class D fires (fires involving flammable metals) is outside the scope of this document in respect of test fires. However, extinguishers claiming Class D suitability are covered in all other respects by the requirements in this document for powder extinguishers. It is considered hazardous for powder and carbon dioxide fire extinguishers to be used on Class F fires. For this reason, powder and carbon dioxide fire extinguishers are excluded for conformance with regard to Class F in this document. NOTE The extinction of a metal fire presents a situation so specific (in terms of the metal itself, its form, the configuration of the fire etc.) that it is not possible to define a representative standard fire for the purposes of testing. The efficiency of extinguishers on Class D fires is established on a case by case basis.

Aerospace series - Cables, electrical, aircraft use - Test methods - Part 812: Return loss (VSWR)

This document specifies methods for measuring return loss respectively voltage standing wave ratio (VSWR), in the required frequency range of coaxial cables. The return loss is used for quantifying the level of the reflected signal due to an impedance mismatch between the cable and the reference impedance and due to structural variations of the impedance along the cable. It is intended to be used together with EN 3475 100 and EN 50289 1 11. NOTE In particular, correction procedures detailed in EN 50289 1 11:2016, Annex B are important to minimize negative effects of cable preparation in the purpose of high frequency range measurements.

Air filters for general ventilation - Part 1: Technical specifications, requirements and classification system based upon particulate matter efficiency (ePM) (ISO/DIS 16890-1:2025)

ISO 16890-1:2016 establishes an efficiency classification system of air filters for general ventilation based upon particulate matter (PM). It also provides an overview of the test procedures, and specifies general requirements for assessing and marking the filters, as well as for documenting the test results. It is intended for use in conjunction with ISO 16890‑2, ISO 16890‑3 and ISO 16890‑4. The test method described in this part of ISO 16890 is applicable for air flow rates between 0,25 m3/s (900 m3/h, 530 ft3/min) and 1,5 m3/s (5 400 m3/h, 3 178 ft3/min), referring to a test rig with a nominal face area of 610 mm × 610 mm (24 inch × 24 inch). ISO 16890 (all parts) refers to particulate air filter elements for general ventilation having an ePM1 efficiency less than or equal to 99 % when tested according to the procedures defined within ISO 16890‑1, ISO 16890‑2, ISO 16890‑3 and ISO 16890‑4. Air filter elements with a higher initial efficiency are evaluated by other applicable test methods (see ISO 29463-1, ISO 29463-2, ISO 29463-3, ISO 29463-4 and ISO 29463-5). Filter elements used in portable room-air cleaners are excluded from the scope of this part of ISO 16890. The performance results obtained in accordance with ISO 16890 (all parts) cannot by themselves be quantitatively applied to predict performance in service with regard to efficiency and lifetime. Other factors influencing performance to be taken into account are described in Annex A.

Water quality - Guidance on pro-rata multi-habitat sampling of benthic macroinvertebrates from rivers and streams

This document gives guidance on procedures for the pro-rata multi-habitat sampling of benthic macroinvertebrates in rivers and streams. The term “pro-rata” reflects the intention to sample all the main riverine habitats present at a monitoring site according to the proportion of the site that it covers. It is an objective way to divide sampling effort among the different habitats. This guidance is applicable to all flowing waters, both artificial, modified and natural. This design enables comparable samples to be collected from any type of river, regardless of the habitats present. The pro-rata multi-habitat sampling is an overall approach rather than a specific method. This document is designed to: — support environmental and conservation agencies to meet the monitoring requirements of the WFD (Article 8, Annex II, and Annex V); — generate data sets appropriate for monitoring and reporting of sites designated under the Habitats Directive and the Birds Directive ensure that samples for comparing the overall composition of invertebrates from different stream types are comparable; — ensure samples for environmental quality assessments across different stream types are comparable even when sampled by different people; and — support river management and restoration initiatives. The pro-rata multi-habitat sample (MHS) provides: — a consistent way of sampling sites that is not dependent on the presence of particular types of habitat; and — guidance on a user-friendly strategy for collecting biological data depending on the distribution of substrate type. It is also ideal for: — understanding the distribution of biological community types across different physical river types; and — quality assessments based on deviation from reference, as adopted in the European Water Framework Directive.
