This document is applicable to stationary and mobile vehicle lifts, which are not intended to lift persons but which are designed to raise vehicles totally, for the purpose of examining and working on or under the vehicles whilst in a raised position. The vehicle lift may consist of one or more lifting units. Power supply to the vehicle lift by internal combustion engines is not considered. The floor or ground supporting the vehicle lift in use is assumed to be horizontal. This document does not exclude a person from entering a lifted vehicle on wheel supporting lifts, e.g. for special works or for periodical technical inspection, and vehicle lifts for rail-bound vehicles. This document does not contain requirements for hazards which may arise on vehicle lifts where the carrying device can be tilted. NOTE Noise does not play a role in vehicle lifts in the majority of cases and is therefore not considered in this document. This document does not apply to: - vehicle lifts movable when loaded; - equipment for power driven parking of motor vehicles (see EN 14010:2003+A1:2009). This document is applicable to vehicle lifts which are manufactured six months after the date of its publication as a European Standard.

This document: a) specifies minimum performance and durability and requirements for infill materials used in synthetic turf, and textile sports surfaces; b) describes how the performance of an infill is to be measured, and the results classified; c) specifies the physical and chemical properties of an infill that are to be declared in a manufacturer’s product declaration; d) specifies minimum production control tolerance to ensure consistency of infill materials between production batches; e) describes how reclaimed infill is to be tested to assess its suitability for reuse. NOTE 1 The sports performance characteristics of a synthetic turf or textile sports surface are provided by the combined characteristics of the synthetic turf or textile surface, any infill within the playing surface pile and any shockpad. The selection of the correct permutations of each is complex and the responsibility of the sports surface designer. NOTE 2 If infill materials migrate from a synthetic turf or textile sports surface into the surrounding natural environment, they become a source of contamination. To minimize the risk this occurring, guidance on how to prevent infill migration from the sports facility is given in CEN Technical Report PD CEN/TR 17519.

Inžinerinių tinklų įrenginių atsparumo ugniai bandymai. 14 dalis. Viename paviršiuje esančių angų sandarinimo priemonės

This part of the EN 1366 series specifies a method of test and criteria for the evaluation (including field of direct application rules) of the ability of a partial penetration seal to maintain the fire resistance of a separating element at the position at which it has been penetrated by a device or devices that passes through one face of the element only. Partial penetration seals are used to seal apertures for electrical sockets, downlighters, media devices, cables and any item which requires an opening to be made in one face of the element of construction but does not include a device which passes through both faces. Supporting constructions are used in this part of the EN 1366 series to represent separating elements such as walls or floors. These simulate the interaction between the test specimen and the separating element into which the sealing system is to be installed in practice. This part of the EN 1366 series is used in conjunction with EN 1363 1. The purpose of a test described in this part of the EN 1366 series is to assess the integrity and insulation performance of the partial penetration seal, of the penetrating service(s) or device(s) and of the separating element in the surrounding area of the partial penetration seal. Where partial penetration seals are installed in ceilings and floors, the loadbearing capacity shall also be considered. No information can be implied by the test concerning the influence of the inclusion of such penetrations and penetration seals on the loadbearing capacity of walls. It is not the intention of this test to provide quantitative information on the rate of leakage of smoke and/or hot gases or on the transmission or generation of fumes. Such phenomena are only to be noted in the test report in describing the general behaviour of test specimens during the test. Tests in accordance with this part of the EN 1366 series are not intended to supply any information on the ability of the partial penetration seal to withstand stress caused by movements or displacements of the penetrating devices. The risk of spread of fire downwards cannot be assessed with this test. Tests in accordance with this part of the EN 1366 series do not address any risks associated with leakage of dangerous liquids or gases caused by failure of the device in case of fire.

This document provides guidance for — the sampling process of the aerosol particles in the air using filter media. This document takes into account the specific behaviour of aerosol particles in ambient air. — Two methods for sampling procedures with subsequent or simultaneous measurement: — the determination of the activity concentration of radionuclides bound to aerosol particles in the air knowing the activity deposited in the filter; — the operating use of continuous air monitoring devices used for real time measurement. This document describes the test method to determine activity concentrations of radionuclides bound to aerosol particles after air sampling passing through a filter media designed to trap aerosol particles. The method can be used for any type of environmental study or monitoring. This document does not cover the details of measurement test techniques (gamma spectroscopy, global alpha and beta counting, liquid scintillation, alpha spectrometry) used to determine the activity deposited in the media filter, which are either based on existing standards or internal methods developed by the laboratory in charge of those measurements. Also, this document does not cover the variability of the aerosol particle sizes as given by the composition of the dust contained in ambient air. This document does not address to sampling of radionuclides bound to aerosol particles in the effluent air of nuclear facilities [see ISO 2889:2021].

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.
