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.

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 describes the following: polling for proximity cards or objects (PICCs) entering the field of a proximity coupling device (PCD); — the byte format, the frames and timing used during the initial phase of communication between PCDs and PICCs; — the initial Request and Answer to request command content; — methods to detect and communicate with one PICC among several PICCs (anticollision); — other parameters required to initialize communications between a PICC and PCD; — optional means to ease and speed up the selection of one PICC among several PICCs based on application criteria; — optional capability to allow a device to alternate between the functions of a PICC and a PCD to communicate with a PCD or a PICC, respectively. A device which implements this capability is called a PXD. This document is applicable to PICCs of Type A and of Type B (as described in ISO/IEC 14443-2), to PCDs (as described in ISO/IEC 14443-2) and to PXDs.

 

 

This document specifies data models and parameters, which can be mapped to communication systems such as SAE J1939/21 or cenelec:proj:56236EN 50325-4(CANopen). The parameters are intended for the usage between body application units (BAU), applicable telematics gateway unit (TGU), and optionally for in-vehicle gateway unit (IGU) as well as fleet management unit (FMU) installed in commercial on-road, off-highway, and off-road vehicles. Body applications include tail-lifts, vehicle-mounted cranes, tippers, refuse collecting equipment, fire-fighting equipment, containers, and refrigerators, but are not limited to them. The Interface is not taking care about safety and cybersecurity between TGU and BAU. Both sides have to take care about their safety and cybersecurity requirements.

This document describes test methods for determining the deviation of the path travelled by a vehicle during a braking manoeuvre induced by an emergency braking system from a pre-defined desired path. The purpose of this document is the evaluation of the vehicle path during and following the system intervention. The corrective steering actions for keeping the vehicle on the desired path can be applied either by the driver or by a steering machine or by a driver assistance system. By making this document open for either open-loop or closed-loop testing, it is possible to apply the test method for evaluating how well the vehicle can be kept within user-defined lane markings after the system intervention, and also for evaluating the precision of the interaction between the emergency braking system and an active lane keeping system. This document applies to heavy vehicles equipped with an advanced emergency braking system (AEBS), possibly as part of (ISO/SAE PAS 22736:2021) level four or higherautomation, including commercial vehicles, commercial vehicle combinations, buses and articulated buses as defined in ISO 3833 (trucks and trailers with maximum weight above 3,5 tonnes and buses and articulated buses with maximum weight above 5 tonnes, according to ECE and EC vehicle classification, categories M3, N2, N3, O3 and O4). NOTE The test method is intended to evaluate the entire vehicle behaviour, not for defining system requirements for the AEBS, which is done in the respective standards created by ISO/TC 204.
