Carbon Black Content Apparatus as per BS:2782 and ASTM D 1603

Carbon Black Content Apparatus is used for determining carbon black content in polyethylene and polypropylene materials. It is calculated by getting the difference in weight before and after treatment in the apparatus.

Carbon black content of plastics test instruments consists of:-

  •  Electric Furnace, at least 20 cm (8 in.) long suitable for
    use with the tubing
  • Tubing,, 4 2.9 cm (1⁄8 in.) in diameter, approximately
    twice as long as the furnace
  •  Stoppers—Two rubber or neoprene stoppers, to fit the
    tube described in 4.2, unless the tube is fitted with ground
    joints and mating connectors.
  • Glass Tubing, 10-mm, of sufficient amount, and matching rubber or plastic tubing for connections.
  • Combustion Boat, approximately 8 by 1.9 by 1.3 cm
    (31⁄2 by 3⁄4 by 1⁄2 in.). Glazed porcelain, quartz high-silica glass,
    or platinum is suitable.
    NOTE 2—A loose-fitting cover for the combustion boat is optional. If
    used, it shall be considered a part of the boat and handled and weighed
    with it.
  • Iron-Constantan Thermocouple, and a potentiometer or
    millivoltmeter suitable for determining temperatures in the
    range 300 to 700 C.
  • Flow Meter, 5 suitable for measuring gas flow at rates of
    1 to 10 L/min.
  • Traps, three glass traps with removable ground-glass
    connected heads and 10-mm diameter inner and connecting
