    Road traffic noise reducing devices - Test method for determining the acoustic performance - Part 6: Intrinsic characteristics - In situ values of airborne sound insulation under direct sound field conditions

    Oprindelse:
    CEN
    Status
    Forslag om nyt arbejdsemne vedtaget
    Beskrivelse
    This European Standard describes a test method for measuring a quantity representative of the intrinsic characteristics of airborne sound insulation for traffic noise reducing devices: the sound insulation index. The test method is intended for the following applications: - determination of the intrinsic characteristics of airborne sound insulation of noise reducing devices to be installed along roads, to be measured either in situ or in laboratory conditions; - determination of the in situ intrinsic characteristics of airborne sound insulation of noise reducing devices in actual use; - comparison of design specifications with actual performance data after the completion of the construction work; - verification of the long term performance of noise reducing devices (with a repeated application of the method); - interactive design process of new products, including the formulation of installation manuals. The test method is not intended for the determination of the intrinsic characteristics of airborne sound insulation of noise reducing devices to be installed in reverberant conditions, e.g. inside tunnels or deep trenches or under covers. Results are expressed as a function of frequency in one-third octave bands, where possible, between 100 Hz and 5 kHz. If it is not possible to get valid measurement results over the whole frequency range indicated, the results need to be given in a restricted frequency range and the reasons for the restriction(s) need to be clearly reported.

    Beskrivelse
    This European Standard specifies the required properties of the piping system and its components made from glass-reinforced thermosetting plastics (GRP) based on unsaturated polyester resin (UP) intended to be used for water supply (drinking or raw) with or without pressure. In a pipework system, pipes and fittings of different nominal pressure and stiffness ratings may be used together. 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. This European Standard is applicable to GRP-UP, with flexible or rigid joints (see 3.33 and 3.34), primarily intended for use in buried installations. It is applicable to pipes, fittings and their joints of nominal sizes from DN 100 to DN 4000, which are intended to be used for the conveyance of water at temperatures up to 50 °C, with or without pressure. This European Standard covers a range of nominal sizes, nominal stiffnesses and nominal pressures. This European Standard is applicable to fittings made using any of the following techniques: a) fabricated from straight pipe; b) moulded by: 1) filament winding; 2) tape winding; 3) contact moulding; 4) hot or cold press moulding. This European Standard is applicable to the joints to be used in GRP-UP piping systems to be used for the conveyance of water, both buried and non-buried. It is applicable to joints, which are or are not intended to be resistant to axial loading. It covers requirements to prove the design of the joint. It specifies type test performance requirements for the following joints as a function of the declared nominal pressure rating of the pipeline or system: c) socket-and-spigot (either integral with pipe or sleeve coupling) or mechanical joint; d) locked socket-and-spigot joint; e) cemented or wrapped joint; f) bolted flange joint.

    Stationary source emissions - Manual method of determination of HCl - Part 2: Gaseous compounds absorption

    Oprindelse:
    CEN
    Status
    Forslag om nyt arbejdsemne under udarbejdelse
    Beskrivelse
    This European Standard describes the Standard Reference Method (SRM) with three alternative analytical techniques for determining gaseous chlorides content emitting to atmosphere from ducts and stacks. The specific components and the requirements for the measuring system are described. A number of performance characteristics with associated minimum performance criteria are specified for the measuring system (see tables 1 and 2 in 7.2). This European standard can be used as a SRM provided the overall uncertainty of the method is less than ± 30,0 % relative at the daily Emission Limit Value (ELV) for incineration and large combustion plants or at the ELV prescribed by the specific regulations for other plants. An Alternative Method to this SRM may be used provided that the user can demonstrate equivalence according to the Technical Specification CEN/TS 14793. This method determines the concentration of chlorinated compounds that give Cl- ions in the absorption solution. This Standard Reference Method has been evaluated during field tests on waste incineration. The method applies to waste gases in which chlorides concentration expressed as HCl may vary between 1mg.m-3 and 5 000 mg.m-3 under normal pressure and temperature conditions (see note), and according to emission limit values laid down in the following Council Directives : - Council Directive 2001/80/EC on the limitation of emissions of certain pollutants into the air from large combustion plants - Council Directive 2000/76/EC on waste incineration plants. Note: The limit values of EU directives are expressed in mg HCl.m-3, on dry basis, at the reference conditions of 273 K and 101,3 kPa and at the reference O2 concentration..
