    Status
    Forslag om nyt arbejdsemne vedtaget
    Beskrivelse
    This European Standard applies to transportable masonry and stone cutting-off machines stationary during work, principally used on job site building construction for cutting-off stones, other mineral construction materials and composite materials having at least one supporting surface. The power for the tool rotation is supplied by electrical or internal combustion prime motor. This European Standard deals with all significant hazards pertinent to masonry and stone cutting-off machines for job site (see clause 4), when they are used as intended and under the conditions foreseen by the manufacturer. This European Standard specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards. These machines are designed for use with rotating diamond cutting-off wheels with a continuous rim and/or segmented rim. This European Standard does not apply to: - metal cutting-off machines; - wood and timber sawing machines; - machines with a feed or descent mechanism other than manual, or with a pedal; - mobile machines on a trolley travelling on the ground; - hand-held portable grinding and cutting-off machines; - hand-held portable grinding and cutting-off machines mounted on a support to be used in a fixed position. This European Standard does not cover the operation of transportable masonry and stone cutting-off machines in potential explosive atmospheres. This European Standard covers electrical hazards making reference to relevant European Standards (see 5.2). Those hazards that are relevant for all mechanical, electrical, hydraulic, pneumatic and other equipment of machinery and that are dealt with in standards for common use are not covered by this European Standard. Reference to pertinent standards of this kind is made where such standards are applicable and so far necessary. In this standard, the masonry and stone cutting-off machines for job site construction are called: "cutting-off machines" or "machines", and

    Geotextiles and geotextile-related products - Screening test method for determining the resistance to hydrolysis in water

    Oprindelse:
    CEN
    International kategori
    Status
    Forslag om nyt arbejdsemne under udarbejdelse
    Beskrivelse
    This European Standard specifies a screening test method for determining the resistance of geotextiles and geotextile-related products to hydrolysis by exposing test specimens to water at elevated temperatures, followed by an evaluation of the changes in properties resulting from such exposure. It is intended as a means of establishing a minimum acceptable level of durability. The test is applicable to any geotextile and geotextile-related product susceptible to hydrolysis, in particular polyester and polyamide based materials, and in addition to the yarns from which these geotextiles are made. Reinforcing materials shall be tested without the coating and manufacturers shall ensure that the degradation of the coating will not attack or have any negative influence on the degradation of the yarns. This method is not intended for determining the resistance of geotextiles to hydrolysis under highly acid or alkaline conditions. NOTE: Performance tests to predict long-term lifetime or to compare products of different polymers or of similar polymers with differing structures can be based on the same method but with a wider range of temperatures and durations.

    Paper and board - Paper and board intended to come into contact with foodstuffs - Determination of cadmium and lead in an aqueous extract

    Oprindelse:
    CEN
    Status
    Forslag om nyt arbejdsemne vedtaget
    Beskrivelse
    This European Standard is one in a series of Standards for the determination of heavy metals in an aqueous extract of paper or board intended for contact with food. This European Standard specifies the test method for the determination of cadmium and lead in an aqueous extract. It is applicable to paper and paperboard with extractable metal contents exceeding - 0,1 mg per kg for cadmium; - 0,6 mg per kg for lead. NOTE 1 – The above limits of determination are achieved by multiplying the actual limits existing today or proposed in Europe by 0,2. NOTE 2 – Metal content levels below those given can be measured by this European Standard if very sensitive equipment is available and if all other laboratory conditions fulfil the requirements for trace element analysis.

    Forslag om nyt arbejdsemne vedtaget
    Beskrivelse
    This European Standard specifies the tabulation method for determining the wall thickness of valve bodies, bonnets and covers with essentially circular cross-section made in forged, cast or fabricated steel. For valve shells with oval, rectangular or non-circular shapes, see 8.6. The range of PN or Class designations for which thicknesses are tabulated is: PN 2,5, PN 6, PN 10, PN 16, PN 25, PN 40, PN 63, PN 100, PN 160, PN 250, PN 320, PN 400, Class 150, Class 300,Class 600, Class 900, Class 1 500, Class 2 500, Class 4 500. Pressure/temperature ratings are specified for each material group for the above PN Standard Class and Special Class designations. The non-destructive examination procedures and acceptance levels that need to be applied to the valve shell components in order for the valve to be used at Special Class pressure/temperature ratings are defined. Details are also given for the alternative rules for small bore valves of DN 65 and smaller designated as Limited Class. This standard does not apply to threaded end valves: – DN 80 or larger; – or which have pressure ratings greater than Class 2 500; – or which operate at temperatures greater than 540 °C. Socket welding end valves DN 80 or larger are outside the scope of this standard.
