Kelio dangos tekstūros apibūdinimas pagal paviršiaus profilį. 5 dalis. Megatekstūros nustatymas (ISO/DIS 13473-5:2024)

ISO 13473-5:2009 specifies procedures for determining the average depth or level of pavement surface megatexture by measuring the profile curve of a surface and calculating megatexture descriptors from this profile. The technique is designed to give meaningful and accurate measurement and description of pavement megatexture characteristics for various purposes. Since there is an overlap between megatexture and the surrounding ranges, the megatexture descriptors unavoidably have a certain correlation with corresponding measures in those ranges. ISO 13473-5:2009 specifies measurements and procedures which are in relevant parts compatible with those in ISO 13473-1, ISO 8608 and EN 13036-5.

Pastatų inžinerinei įrangai skirtų elektroninių produktų katalogų duomenų struktūros. 5 dalis. Produktų katalogo mainų formatas (ISO/DIS 16757-5:2024)

The focus of ISO 16757 is the support of manufacturers to provide their product data in electronic product catalogues. This part of the standard – ISO 16757 Part 5: Product catalogue exchange format - describes how product catalogue data is exchanged as IFC format according to ISO 16739-1 from manufacturers to designers of building services systems. With ISO 16739-1 (IFC), an open language exists for the creation, transfer and maintenance of design models. prEN 17549-1 and prEN 17549-2 define the data exchange of scalable product properties within IFC. These standards provide a Model View Definition (MVD), a subset of ISO 16739-1 from an information technology perspective. It focuses on core classes and relies on external data dictionaries to describe business semantics. This document completes the description of the IFC-based data exchange format for manufacturer catalogues by describing how to model: • Catalogue metadata • Product classes • Constraints for parametric data • Product accessory structures • Constraints for assembling composable products and accessories • Reusable and multiply used data blocks • Product properties as defined in the related library • Static product properties • Dynamic computable properties • Geometric data of product spaces • Geometric data of product symbols • Geometric data of product shape • Geometric data of product ports • Article numbers • Etc. This document focuses only on the format of the data exchanged and not on how to process it. This document is aimed at both software manufacturers for the construction sector and professionals in the sector who use their software.
