    Forslag om nyt arbejdsemne under udarbejdelse
    Beskrivelse
    This European Standard specifies units made from polyester resin concrete (PRC, see 3.1.18), and their joints, for the construction of inspection chambers with inverts not exceeding 2 m deep and for manholes, intended to be used within a drain or sewer system operating without pressure. It applies to products for use outside buildings in buried installations to be installed by open-trench techniques. This document applies to nominal sizes from DN 600 to DN 3000 for chamber rings and shaft rings having a circular shape. The intended use of these products is to provide access to buried drain or sewer systems for the conveyance of wastewater, i.e. sewage, rainwater and surface water, at temperatures up to 50 °C, without pressure or occasionally at a head of pressure up to 0,5 bar ), and installed in areas subjected to vehicle and/or pedestrian traffic and outside buildings. NOTE 1 The attention of readers is drawn to applicable requirements contained in EN 476. This standard specifies definitions, requirements and characteristics of units and their joints for the construction of manholes and inspection chambers, of materials, test methods, marking and evaluation of conformity. The units are classified on the basis of its type and the type of structure they are intended to be used. NOTE 2 It is the responsibility of the purchaser or specifier to make the appropriate selections, taking into account their particular requirements and any relevant national regulations and installation practices or codes.

    Status
    Forslag om nyt arbejdsemne under udarbejdelse
    Beskrivelse
    This European Standard specifies requirements, methods of test and performance criteria against which the compatibility of components and their performance can be assessed when used in combination to form an electrically controlled hold-open system. It also specifies requirements for the integrity of such hold-open systems when connected to fire detection and fire alarm systems or other systems, including the signal exchange and technical data for interfaces. This European Standard provides requirements for the application of electrically controlled hold-open systems used for fire/smoke doors in buildings, where such doors are required to be self-closing. It covers planning, design (see Annex A), installation (see Annex B), commissioning, use and maintenance (see Annex E) of hold-open systems, intended for the protection of life and/or the protection of property. This may also include hold-open systems, or components of the hold-open system, that are self-contained in a single enclosure. Electrically controlled hold-open systems manufactured, installed and serviced in accordance with this European Standard are recommended for use wherever there is a requirement for reliable hold-open and release of an individual self-closing fire/smoke door assembly in the case of fire. The use of hold-open systems for closures in conveyor systems conforming to EN 1366-7, which applies in conjunction with EN 1363-1, may require additional proof of suitability, which is not covered by this European Standard. This European Standard does not cover design, installation, commissioning, use and maintenance of building fire detection and fire alarm systems (covered by CEN/TS 54-14) but does cover the connection of hold-open systems conforming to this European Standard to building fire detection and fire alarm systems, under certain prescribed conditions.

    This part of ISO 14644 addresses the cleaning (removal of contaminants) to a specified degree on cleanroom surfaces, surfaces of equipment in the cleanroom and surfaces of materials in the cleanroom. The following are excluded from this document: - product and process cleaning; - cleaning of microbiological contamination; - detailed cleaning methods and procedures. This part of ISO 14644 provides guidance about different cleaning techniques, classified, e.g. as wet/dry and physical/chemical. This part of ISO 14644 provides guidance on which methods should be used for achieving required Surface cleanliness by particle concentration (SCP) and Surface cleanliness by chemical concentration (SCC) classes and which techniques should be considered to achieve these specified levels. The efficacy of cleaning techniques makes reference to the cleanliness classes and associated test methods found in ISO 14644-8, -9 and -10. The following matters of general guidance are provided: - assessment of adverse effects such as health and safety considerations, surface/material properties; - compatability of surfaces with the cleaning technique, - surface attributes such as morphology; - configurations such as crevices, holes and cracks, - waste and effluent - suitability of cleaning agents and materials (e.g. purity, cleanliness, properties)

    This European Standard specifies performance requirements for the strength and durability of hardware for the operation of movable shutter sashes including requirements and test methods. This European Standard is applicable to hardware for side-hung and top-hung shutters comprising one or more shutter sashes. The requirements and test methods of this European Standard are applicable to the following: shapes and dimensions of sash hinges, double-sashed shutter hinges and frame hinges shapes and dimensions of frame hinges and sash hinges with arrest function Only the corrosion requirements of 4.7 are applicable to double-sash shutter latches, locking-rods, decorative corner-brackets, handles, stops without automatic arrest function, central hinges, shutter catches with automatic arrest function and other hardware components for window and door shutters. NOTE 1 – The sashes of side-hung shutters may have additional projecting shutter-inserts. The hardware for these projecting shutter-inserts is not covered by the scope of this European Standard. NOTE 2 – If due to the hardware fixing type or the dead weight of the described test shutter, this can not be used, a corresponding system sash with the same dimensions (800 mm wide ï‚´ 1 400 mm high) can be tested. This is particularly valid for hardware used exclusively in a complete modular system from a systems manufacturer (consisting of the hardware components, frame profiles and panel units as well as the necessary fixing materials). NOTE 3 – Tower bolts and locking-rods should conform to EN 12051. NOTE 4 – Fixings used to attach hardware to shutters are not covered by this European Standard. To allow a choice of items from a single source, so-called ""product group"" of elements may be nominated by the manufacturer. The single components may be called ""product group"" components, if these are approved by accredited test authorities commissioned to test, based upon the comparable features; for example hinge featur ...
