This European standard specifies a method for the determination of total dissolved solids (TDS) in water and eluates, provided they are not volatile under the conditions specified or that they do not release water molecules from hydration. It applies to water and eluates containing more than 200 mg/l of total dissolved solids. Samples with lower amounts of dissolved solids can be analyzed by repetition of the drying step.

This European Standard describes the necessary steps to be performed before carrying out ecotoxicity tests on wastes. The purpose of this European Standard is to provide guidance on the taking of the sample, transport, storage of wastes and to define preparation, for the determination of ecotoxicological properties of wastes under the conditions specified in this European Standard by biological testing either as raw wastes or water extracts from wastes. Sample preparation for other applications (e.g. assessment of waste effects on aquatic and terrestrial organisms in a disposal scenario) is not considered.
Specifying a test battery to characterize ecotoxicological properties of wastes is not in the scope of this European Standard.
This European Standard is applicable to solid and liquid wastes.

Scope of the proposed deliverable.
This International Standard specifies the measurement of explosive and related nitrocompounds
compounds using liquid chromatography–tandem mass spectrometry (LC-MS/MS) in soil and soilmaterials. This method is applicable to 12 compounds (1,3-DNB, 1,3,5-TNB, 2,4-DNT, 2,6-DNT, 2,4,6-TNT, 4-A-2,6-DNT, 2-A-4,6-DNT, Tetryl, Hexyl, RDX, HMX, PETN) listed in ISO 11916-1(soil, HPLC/UV method) except nitrobenzene, 2-nitortoluene, 3-nitrotoluene and 4-nitrotoluene. In particular,this method is effective for the analysis of PETN, 1,3,5-TNB and tetryl which showed poor interlaboratory trial results with ISO 11916-1. Under the conditions specified in this document, concentrations as low as 0,005 mg/kg to 0,014 mg/kg-dry matter can be determined, depending on the substance.
Purpose and justification of the proposal*
Currently two ISO standards exist for the analysis of explosives and related compounds in soil: ISO 11916-1(HPLC/UV method), ISO 11916-2(GC-ECD or MS method). According to the results of interlaboratory trial with ISO 11916-1, it showed some problematic aspects to analyze PETN, 1,3,5-TNB and tetryl. In case of ISO 11916-2, it also gave poor inter-laboratory trial results for 1,3,5-TNB. Therefore, it is necessary to develop new method effectively applicable to the determination of PETN, 1,3,5-TNB and tetryl.
In addition to this, lower risk-based PRGs (Preliminary Remediation Goal), new regulatory concerns, and change of land use have created the atmosphere to apply more sensitive and selective instruments to determine explosive and related compounds. From the view of these aspects, liquid chromatography–tandem mass spectrometry (LC-MS/MS) is one of alternative methods for these purposes. LC-MS/MS method provides 10-20 times or much lower detection limit than that of HPLC/UV method and is recommendable to determine PETN, 1,3,5-TNB and tetryl.
Also LC-MS/MS method is getting more familiar in ISO standard development (e.g. ISO/CD22104 Water quality--Microcystins, ISO/NP21677 Water quality--HBCD, ISO/CD21675 Water quality--PFAS).

This document applies to vehicle-mounted mobile systems (also known as mobile systems or mobile monitors) that are used for the detection of illicit trafficking of radioactive materials; these instruments may also be used for protection of major public events and for rapid screening of large areas. These vehicle-mounted mobile systems consist of one or more radiation detectors mounted in a vehicle, e.g., car or van, which travels predominantly on public roads.

This document specifies a method for the enumeration of Pseudomonas aeruginosa 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.
This document is applicable to a range of types of water. For example, hospital waters, drinking water
and non‐carbonated bottled waters intended for human consumption, groundwater, swimming pool
and spa pool waters including those containing high background counts of heterotrophic bacteria.
This document does not apply to carbonated bottled waters, flavoured bottle waters, cooling tower
waters or marine waters, for which the method has not been validated. These waters are, therefore,
outside the scope of this document. Laboratories can employ the method presented in this document
for these matrices by undertaking appropriate validation of performance of this method prior to use.
The test is based on a bacterial enzyme detection technology that signals the presence of P. aeruginosa
through the hydrolysis of a 7‐amino‐4‐methylcoumarin aminopeptidase substrate present in a special
reagent. P. aeruginosa cells rapidly grow and reproduce using the rich supply of amino acids, vitamins
and other nutrients present in the reagent. Actively growing strains of P. aeruginosa have an enzyme
that cleaves the 7‐amido‐coumarin aminopeptidase substrate releasing a product which fluoresces
under ultraviolet (UV) light. The test described in this document provides a confirmed result within
24 h with no requirement for further confirmation of positive wells.

This document sets out requirements for bio-based surfactants in terms of properties, limits, application classes and test methods. It establishes the characteristics and details for assessment of bio-based surfactants as to whether they:
— are fit for purpose in terms of performance related properties;
— comply with the requirements regarding the health, safety and environment which apply to general surfactants;
— are derived from a certain minimum percentage of biomass; and
— comply with at least similar sustainability criteria as comparable (non-bio-based) surfactants.
The criteria of the regulation on Registration, Evaluation, Authorization and Restriction of Chemicals (REACH)  also apply to bio-based surfactants.
NOTE EN 16575 defines the term “bio-based” as derived from biomass and clarifies that “bio-based” does not imply “biodegradable”. In addition, “biodegradable” does not necessarily imply the use of “bio-based” material.

This document aims to simulate the mechanical loads that could be imparted to passive fire protection (PFP) materials and systems by explosions resulting from releases of flammable gas, pressurised liquefied gas or flashing liquid fuels that may precede a fire. This document can also be applicable to dust explosions. Gas explosions can give rise to pressure and drag forces. Damage to PFP materials in a gas explosion can be caused by the direct effects of pressure and drag loadings and by the deflection of the substrate supporting the PFP material. Other parts of the ISOÂ 23693 series will deal with a range of common types of specimen that could be tested against the mechanical loads generated.
