This document applies to an articulated extraction arm used as a local exhaust device in laboratories and comprised of a specific capture device (receiving, enclosing or capture hood, nozzle or flat screen) connected to a specific extraction arm which is articulated ducting to move air from the capture device to discharge.<\/p>\n

This document specifies:<\/p>\n

    \n
  1. \n

    a method for type testing;<\/p>\n<\/li>\n

  2. \n

    a method to assess the three-dimensional capture zone of local exhaust devices mounted on an articulated extract arm;<\/p>\n<\/li>\n

  3. \n

    a method for assessing the isothermal and low energy emission release capture efficiency of local exhaust devices connected to an articulated extract arm and its robustness to a challenge of air disturbance directly in front of and in close proximity to the capture hood and release source positioned on a table;<\/p>\n<\/li>\n

  4. \n

    a method for establishing the reachable, three-dimensional workspace of local exhaust devices mounted on an articulated extract arm by measuring the possible positions of the opening of the device;<\/p>\n<\/li>\n

  5. \n

    a method for measuring the pressure drop and noise level in the type test and at onsite commissioning;<\/p>\n<\/li>\n

  6. \n

    instructions for marking the device and recommended information to transfer to users in the product manual;<\/p>\n<\/li>\n

  7. \n

    guidance for use describing the limitations of local exhaust devices with articulated extract arm for different airflow rates establishing the capture zone;<\/p>\n<\/li>\n

  8. \n

    guidance on selection, installation, commissioning, and testing of articulated extract arms and their local exhaust ventilation systems.<\/p>\n<\/li>\n<\/ol>\n

    The standard covers only product performance test methods. Occupational health and safety assessments methods are not included in this standard.<\/p>\n

    Point sources with initial velocity due to temperature, pressure release, work process or similar are not covered by this standard.<\/p>\n

    The scope does not include filtration requirements and impact of fully or partly recirculated airflow extracted by an articulated extract arm.<\/p>\n","protected":false},"excerpt":{"rendered":"
