This document defines a measure for the spectral quality of LED luminaires in terms of the ratio of the amount of visual light emitted by the luminaire versus the amount effective for charging photoluminescent products contained in that spectrum. Fulfilment of this document by a LED luminaire will ensure general compatibility of the luminaire with photoluminescent marking systems. This document alone does not provide any means of compliance to fulfil any airworthiness requirements. For a specific aircraft installation, the spectral power distribution and illuminance at the photoluminescent marking systems are relevant.

This document specifies video coding technologies for machine consumption.

 

Conventional video coding technologies aim for the best video under certain bit-rate constraints for human consumption. However, with the emergence of artificial intelligence systems, along with the abundance of sensors, many artificial intelligence platforms have been implemented with massive data requirements including scenarios such as connected vehicles, video surveillance, and smart city. The sheer quantity of data being produced constantly leads previous methods with a human in the pipeline to be inefficient and unrealistic in terms of latency and scale. There are additional concerns in transmission and archive systems which require a more compact data representation and low latency solution. This led to the introduction of the Video Coding for Machines standard specified in this document.

 

In some cases, machines will communicate amongst themselves to perform tasks without a human in the mix, while in others there will be a need for additional human consumption of the specific decompressed stream. This specific scenario is possible in surveillance use cases, where a human “supervisor” occasionally searches for a specific person, or scene in video. In other cases, the corresponding bitstream is used for both human and machine consumption.

 

The syntax, semantics, and decoding processes that are required to decode a bitstream are described in this document.

It also provides an implementation schema for binding a concrete, implementable, conformance-testable coverage structure as defined in ISO 19123-2 [2].

The purpose of this document is to describe a test for the determination of water-soluble sulphate content in a soil sample (WS), by initial dissolution in demineralized water and subsequent precipitation with a saturated barium chloride (BaCl2) solution, according to the following reaction: The presence of multi-valent anions in soils, such as phosphates or oxalates, can interfere with the method as they are liable to co-precipitate with the BaCl2 solution, leading to a mass increase in the residue and a subsequent overestimation of the water-soluble sulphate content. Carbonates are excluded from this interference as they are removed as CO2 (g) through the preliminary addition of hydrochloric acid. Annex B specifies a qualitative method for the rapid detection of water-soluble sulphates in soil by aqueous dissolution and subsequent precipitation with BaCl2. Furthermore, Annex C provides a quantitative method for the determination of the gypsum (CaSO4·2H2O) content in a soil sample, derived from the non-gypsum water-soluble sulphate content previously determined. The results obtained in accordance with this document do not represent the total sulphate content of the soil, but exclusively the fraction soluble in water under the specific conditions defined in this document. These results are not comparable with those obtained by CEN/TS 17685 5:2026, relative to the determination of water-soluble salt content in soils (WSS).

 

The purpose of this document is to describe a gravimetric method for the determination of the water-soluble salt content (WSS) in soils. These salts typically comprise inorganic ions such as sulphates, chlorides, nitrites, nitrates, bicarbonates, sodium, ammonium, calcium, magnesium, and strontium. The method involves initial dissolution in demineralised water and subsequent determination of the mass of the residue obtained by evaporation. The results obtained in accordance with this document do not represent the total salt content of the soil, but exclusively the fraction soluble in water under the specific conditions defined in this document. These results are not comparable with those obtained by TS 17685 4:2026, relative to the determination of water-soluble sulphate content in soils.

 

This document specifies a method for the enumeration of culturable microorganisms in water by counting colonies on a low-nutrient agar culture medium by spread plate inoculation after incubation at 22 °C for 7 days. This document is applicable to: — water from the treatment process of public drinking water supplies (e.g. process water in the waterworks); — chlorinated and non-chlorinated tap water in distribution systems and containers; — bottled water; — well water intended for human consumption. For detailed information on the performance characteristics, see Annex B. This document can be applied to other water matrices if the appropriate validation of performance of this method has been undertaken by the laboratory prior to use.

 

This document specifies a method for the enumeration of culturable microorganisms in water by counting the colonies on a low-nutrient agar culture medium after incubation at 22 °C for 7 d. The method is intended to measure the operational efficiency of the treatment process of public drinking water supplies, including the water in distribution systems and containers. The method is particularly suitable to monitor water for human consumption which is low in nutrients and is distributed in temperatures below 20 °C. The method can be applied to all types of water, including pool and spa waters. NOTE 1 The low-nutrient agar in use in this document usually gives higher colony counts from water samples than nutrient-rich formulations of culture media typically used for enumeration of culturable microorganisms. NOTE 2 The method is also applicable for waters of very low nutrient content such as de-ionised, distilled or reverse osmosis waters. NOTE 3 This document describes the use of R2A medium. There are other formulations available, e.g. R3A medium that might be suitable for certain applications but go beyond the scope of this document.
