    Screw Conveyors and product receivers as explosion isolation systems

    Oprindelse:
    CEN
    Status
    Forslag om nyt arbejdsemne under udarbejdelse
    Beskrivelse
    This Technical Report describes how screw conveyors and product receivers can be used as an explosion isolation system for dust explosions using the product handled by this equipment as a means for explosion isolation. The report specifies test methods for evaluating the efficacy of these isolation techniques depending on both the mechanical layout of the equipment itself and the properties of the product handled. It covers e.g.: a) an overview of information available from research performed and experience obtained in industry b) important factors affecting the efficiency of such techniques of explosion isolation c) proposed ways of testing for evaluating the efficacy of these isolation techniques d) installation instructions including monitoring equipment e) maintenance instructions. The report only covers the use of screw conveyors and product receivers as a means of explosion isolation system for avoiding explosion propagation between interconnected enclosures in which an explosion may result as a consequence of ignition of explosive dust-air mixtures. This standard is not applicable for explosions of materials listed below, or for mixtures containing some of those materials: a) unstable materials that are liable to dissociate; b) explosive materials; c) pyrotechnic materials. For other explosion isolation systems and devices reference is made to EN 15089, EN-ISO 16852 (flame arresters), EN 16020 (explosion diverters)

    Forslag om nyt arbejdsemne under udarbejdelse
    Beskrivelse
    This European Standard sets requirements for personal hearing protection devices in relation to Directive 89/686/EEC – Personal Protective Equipment. The particular requirement in relation to the ability of hearing protectors to reduce noise below daily limit levels is addressed in the standard by requiring the sound attenuation of the hearing protectors, measured in accordance with EN 24869-1, to be not less than a specified minimum. Further, by requiring that the measured sound attenuation would be declared, the selection of suitable hearing protectors for individual circumstances may be undertaken according to established practice. This standard would cover hearing protectors for children aged 5 -16.
