This document specifies the definitions and requirements for solid wall pipes with smooth internal and external surfaces, extruded from the same formulation throughout the wall, fittings and the system of unplasticized poly(vinyl chloride) (PVC-U) piping systems in the field of non-pressure underground drains and sewers for wastewater. NOTE 1 Products complying with this document can also be used in non-pressure underground drains and sewers for surface water. This document also specifies test methods and test parameters. This document is applicable to: - solid wall pipes and fittings which are intended to be used buried underground outside the building structure reflected in the marking of the products by “U”, and - solid wall pipes and fittings which are intended to be used buried underground both outside (application area code “U”) and within the building structure reflecting on the marking of products by “UD”. NOTE 2 Multilayer pipes with different formulations throughout the wall and foamed core pipes are covered by EN 13476-2 [1]. This document covers a range of pipe and fitting sizes, stiffness classes, and gives recommendations concerning colours. NOTE 3 It is the responsibility of the purchaser or specifier to make the appropriate selection from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes. In conjunction with CEN/TS 1401 2 [7] it is applicable to PVC-U pipes and fittings, their joints and to joints with components of other plastics and non-plastics materials intended for buried piping systems for non-pressure underground drains and sewers. NOTE 4 Pipes, fittings and other components conforming to any of the plastics product standards listed in Annex C can be used with pipes and fittings conforming to this document, provided they conform to the requirements for joint dimensions given in Clause 10 and to the requirements of Table 16.

This document describes a taxonomy of the AI tasks related to computer vision. It includes AI tasks pertaining to either the analysis or generation of images and videos.

 

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.

This document specifies a test method for the simultaneous determination of primary aromatic amines (PAAs) in organic pigments using external reference standards. The separation, identification and quantification of PAAs are achieved by high-performance liquid chromatography (HPLC) analysis with gradient elution and diode array detection (DAD) and/or mass spectrometry detection (MSD) after an extraction step. This analytical procedure can be applied to all organic pigments. The method allows the determination of extractable PAA content including sulfonated PAAs.
