Water quality - Determination of nitrate in water using small-scale sealed tubes - Part 2: Chromotropic acid colour reaction (ISO 23696-2:2023)

This document specifies a method for the determination of nitrate as NO3-N in water of various origin such as natural water (including groundwater, surface water and bathing water), drinking water and wastewater, in a measuring range of concentration between 0,20 mg/l and 30 mg/l of NO3-N using the small-scale sealed tube method. Different measuring ranges of small-scale sealed tube methods can be required. The measuring ranges can vary depending on the type of the small-scale sealed tube method of different manufacturers. It is up to the user to choose the small-scale sealed tube test with the appropriate application range or to adapt samples with concentrations exceeding the measuring range of a test by preliminary dilution. NOTE 1 The results of a small-scale sealed tube test are most precise in the middle of the application range of the test. Manufacturers' small-scale sealed tube methods are based on chromotropic colour reaction, depending on the typical operating procedure of the small-scale sealed tube used, see Clause 9. NOTE 2 Laws, regulations or standards can require that the data is expressed as NO3 after conversion with the stoichiometric conversion factor 4,426 81 in Clause 11. NOTE 3 In the habitual language, use of sewage treatment and on the displays of automated sealed-tube test devices, NO3 without indication of the negative charge has become the common notation for the parameter nitrate and especially for the parameter nitrate-N. This notation is adopted in this document even though not being quite correct chemical nomenclature.

Petroleum and related products - Determination of sulfur content of automotive fuels - Ultraviolet fluorescence method (ISO/DIS 20846:2025)

This document specifies an ultraviolet (UV) fluorescence test method for the determination of the sulfur content of the following products: — having sulfur contents in the range 3 mg/kg to 500 mg/kg, — motor gasolines containing up to 3,7 % (m/m) oxygen [including those blended with ethanol up to about 10 % (V/V)], — diesel fuels, including those containing up to about 30 % (V/V) fatty acid methyl ester (FAME), — having sulfur contents in the range of 3 mg/kg to 45 mg/kg, — synthetic fuels, such as hydrotreated vegetable oil (HVO) and gas to liquid (GTL). Other products can be analysed and other sulfur contents can be determined according to this test method, however, no precision data for products other than automotive fuels and for results outside the specified range have been established for this document. Halogens interfere with this detection technique at concentrations above approximately 3 500 mg/kg. NOTE 1 Some process catalysts used in petroleum and chemical refining can be poisoned when trace amounts of sulfur-bearing materials are contained in the feedstocks. NOTE 2 This test method can be used to determine sulfur in process feeds and can also be used to control sulfur in effluents. NOTE 3 For the purposes of this document, "% (m/m)" and "% (V/V)" are used to represent the mass fraction, w, and the volume fraction, φ, of a material respectively. NOTE 4 Sulfate species in ethanol do not have the same conversion factor of organic sulfur in ethanol. Nevertheless, sulfates have a conversion factor close to that of organic sulfur. NOTE 5 Nitrogen interference can occur, see 6.5 for further guidance.

Milk, milk products, infant formula and adult nutritionals - Determination of fatty acids composition - Capillary gas chromatographic method (ISO/FDIS 16958:2025)

ISO 16958:2015 specifies a method for the quantification of individual and/or all fatty acids in the profile of milk, milk products, infant formula and adult nutritional formula, containing milk fat and/or vegetable oils, supplemented or not supplemented with oils rich in long chain polyunsaturated fatty acids (LC-PUFA). This also includes groups of fatty acids often labelled [i.e. trans fatty acids (TFA), saturated fatty acids (SFA), monounsaturated fatty acids (MUFA), polyunsaturated fatty acids (PUFA), omega-3, omega-6 and omega-9 fatty acids] and/or individual fatty acids [i.e. linoleic acid (LA), α-linolenic acid (ALA), arachidonic acid (ARA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)]. The determination is performed by direct transesterification in food matrices, without prior fat extraction, and consequently it is applicable to liquid samples or reconstituted powder samples with water having total fat ≥ 1,5 % m/m. The fat extracted from products containing less than 1,5 % m/m fat can be analysed with the same method after a preliminary fat extraction using methods referenced in Clause 2. Dairy products, like soft or hard cheeses with acidity level ≤ 1 mmol/100 g of fat, can be analysed after a preliminary fat extraction using methods referenced in Clause 2. For products supplemented or enriched with PUFA with fish oil or algae origins, the evaporation of solvents should be performed at the lowest possible temperature (e.g. max. 40 °C) to recover these sensitive fatty acids.

Freight containers - Coding, identification and marking (ISO/DIS 6346:2025)

1.1 This document provides a system for the identification and presentation of information about freight containers. The identification system is intended for general application, for example in documentation, control and communications (including automatic data processing systems), as well as for display on the containers themselves. The methods of displaying identification and certain other data (including operational data) on containers by means of permanent marks are included. 1.2 This document specifies: a) a container identification system, with an associated system for verifying the accuracy of its use, having: — mandatory marks for the presentation of the identification system for visual interpretation, and — features to be used in optional Automatic Equipment Identification (AEI) and electronic data interchange (EDI); b) a coding system for data on container size and type, with corresponding marks for their display; c) operational marks, both mandatory and optional; d) physical presentation of marks on the container. 1.3 All markings not denoted as ‘optional’ shall be considered mandatory. The terms “mandatory” and “optional” in this document are used to differentiate those ISO marking provisions which shall necessarily be fulfilled by all containers from those which are not required of all containers. The optional marks are included to further comprehension and promote uniform application of the optional mark. If a choice has been made to display an optional mark, the provisions laid down in this document relating to the mark shall be applied. The terms “mandatory” and “optional” do not refer to requirements of any regulatory body. 1.4 This document applies to all freight containers covered by International Standards ISO 668, parts 1 to 5 of ISO 1496, ISO 8323 and should, wherever appropriate and practicable, be applied: — to containers other than those covered by the International Standards mentioned in Clause 2; — to container-related and/or detachable equipment. NOTE 1 Containers marked according to previous editions of ISO 6346 need not be re-marked. 1.5 This document does not cover temporary operational marks of any kind, permanent marks, data plates, etc. which may be required by intergovernmental agreements, national legislation or nongovernmental organizations. NOTE 2 Some of the major international conventions whose container-marking requirements are not covered in this document are as follows: — International Convention for Safe Containers (1972, as amended) (CSC), International Maritime Organization (IMO); — Customs Convention on Containers 1956 and 1972, related to temporary admission and transport under customs seal. — Convention on Temporary Admission (Istanbul, 26 June 1990), related to temporary admission. It should not be assumed that this list is exhaustive. This document does not cover the display of technical data on tank containers (see ISO 1496-3), nor does it, in any way, include identification marks or safety signs for items of cargo which may be carried in freight containers.
