    Qualification testing of welders for underwater welding - Part 2: Diver-welders and welding operators for hyperbaric dry welding

    Oprindelse:
    CEN
    Status
    Forslag om nyt arbejdsemne vedtaget
    Beskrivelse
    This standard applies to welding processes where the skill of the diver-welder or welding operator has a significant influence on weld quality. This standard specifies essential requirements, ranges of approval, test conditions, acceptance requirements and certification for the approval testing of diver-welder or welding operator performance for the welding of steels underwater in a hyperbaric dry environment. The recommended format for the certificate of approval testing is given in Annex A. During the approval test the diver-welder or welding operator should be required to show adequate practical experience and job knowledge (test non mandatory) of the welding processes, materials and safety requirements for which he is to be approved, information on these aspects is given in Annex B. This standard is applicable when the diver-welder s or welding operator s approval testing is required by the purchaser, by inspection authorities or by other organisations. The welding processes referred to in this standard include fusion welding processes which are designated as manual or partly mechanized welding for diver-welders and fully mechanized or automatic welding for operators (see 5.2). All new approvals are in accordance with this standard from the date of this issue. However, this standard does not invalidate previous diver-welder or welding operator approvals made to former national standards or specifications, providing the intent of the technical requirements is satisfied and the previous approvals are relevant to the application and production work on which they are to be employed. Also, where additional tests should be carried out to make the approval technically equivalent it is only necessary to do the additional tests on a test piece which should be made in accordance with this standard.

    Animal feeding stuffs: Methods of sampling and analysis - Determination of calcium, sodium, phosphorus, magnesium, potassium, sulphur, iron, zinc, copper, manganese and cobalt after pressure digestion by ICP-AES

    Oprindelse:
    CEN
    Status
    Forslag om nyt arbejdsemne vedtaget
    Beskrivelse
    This European Standard specifies a method for the determination of the minerals calcium, sodium, phosphorus, magnesium, potassium and sulphur and the elements iron, zinc, copper, manganese, cobalt in animal feeding stuffs by inductively coupled plasma atomic emission spectrometry (ICP-AES) after pressure digestion. The method was fully statistically tested and evaluated within 11 animal feeding stuff samples for the minerals calcium, sodium, phosphorus, magnesium, potassium and sulphur and the elements iron, zinc, copper, manganese and cobalt. For potassium and sulphur the HORRAT values were mostly higher than 2. Therefore, for these elements the method is more applicable as a screening method and not for confirmatory purposes. Other elements like molybdenum, lead, cadmium, arsenic were not fully statistically tested and evaluated within 11 animal feeding stuff samples because these elements did not occur in concentrations higher than the limit of quantification in most of these samples. A single laboratory validation is therefore necessary for the use of this multi element method for these elements. For phyllosilicates (e.g. koalinitic clays) and feeds containing phyllosilicates the extractable lead content is of concern regarding current legislation and therefore the results of lead when using this standard may be overestimated. If the result for lead in phyllosilicates or feeds containing phyllosilicates is non compliant to current legislation using this standard the extraction mode 9.1.4 of EN 15510 shall be used for confirmatory purposes. The method limit of quantification for each element is dependent on the sample matrix as well as on the instrument. The method is not applicable for determination of low concentrations of elements. A limit of quantification of 1 mg/kg should normally be obtained. NOTE – This method can also be used for the determination of minerals in products with high mineral content (> 5 %), yet for this purpose other more precise analytical techniques are available.

    This European Standard specifies requirements and test methods for durability, strength, security and functionality of mechanically operated multipoint locks and their locking plates for use in doors in buildings. This European Standard covers multipoint locks which are either manufactured and placed on the market in their entirety by one producer or assembled from sub-assemblies produced by more than one producer and subsequently placed on the market as a kit in a single transaction. This standard specifies Multipoint locks and locking systems intended for use in different environmental and security conditions, thus necessitating different grades. This European standard does not specify single point locks or their locking plates which are specified by EN 12209. This standard specifies the dimensions and properties required for security and for the assessment of smoke door suitability. This European standard is not applicable to cylinders, handles, locks for windows, padlocks, locks for safes, furniture locks or prison locks. Assessment of the contribution of the product to the fire resistance of specific fire/smoke resisting door assemblies is beyond the scope of this European Standard.

    Ventilation for buildings - Ductwork - Cleanliness of ventilation systems

    Oprindelse:

    Status
    Forslag om nyt arbejdsemne vedtaget
    Beskrivelse
    Revision of EN 15780: This European Standard applies to both new and existing ventilation and air conditioning systems and specifies the assessment criteria of cleanliness, cleaning procedures of these systems, and the validation of the effectiveness of cleaning applies also to products, which conform to EN 1505, EN 1506, EN 13053, EN 13180 and EN 13403, used in air conditioning and ventilation systems for human occupancy defined in the scope of CEN/TC 156. This European Standard does not apply to installations for industrial processes. Cleanliness of ventilation systems is considered important for human comfort and health, energy consumption, system service life and for cleanliness of operations or processes carried out in the ventilated area. Considerations for change of component as an alternative for cleaning (e.g. in case of flexible ducts and air filters) are also included. This European Standard specifies general requirements and procedures necessary in assessing and maintaining the cleanliness of ducted ventilation, including: - cleanliness quality classification; - how to assess the need for cleaning (visual, measurements); - assessment frequency (general guidance); guidance of system inspections in accordance with EN 15239, and EN 15240 when relevant; - selection of cleaning method – to be in line with handing over documentation according to EN 12599; - how to assess the result of cleaning. This European Standard is a parallel standard to EN 12097, which specifies requirements for dimension, shape and location for access panels for cleaning and service in ductwork systems. This European Standard is made as an umbrella standard with informative annexes that can be revised, completed and further added in future revisions of this European Standard for specific system types, and products or applications in the system, such as: - Air Handling Units (AHU); - filter; - humidifiers; - heat recovery units; - decentralised air treatment units such as fan-coil units, indu
