UN6HA1 Composite Packaging

Our CSCP2-11-01 is a 5 gallon steel composite drum (pail) with a UN rating of UN6HA1/Y1.8/100.  An explanation of this rating is as follows:

    • UN = United Nations
    • 6     = Composite
    • H    = Plastic
    • A    =  Steel
    • 1     = Tight Head
    • Y    = Packing Groups II or III
    • 1.8  = Maximum specific gravity the container has been tested to hold for 5 minutes
    • 100 =Maximum hydrostatic pressure the container has been tested to hold for 5 minutes

This drum may be used for both hazardous (packing group II & III) and non-hazardous liquids.  It is a steel pail with a plastic liner.  The liner is produced separately from the pail, and is hand assembled.  This drum comes with a dust cap attached.  The dust cap is removed and the pail is filled with liquid.  A Rieke Flexspout (sold separately) is then applied with a Rieke Flexspout crimping tool (also sold separately).  The rim of the plastic liner (or bladder) partially extends over the steel opening in the pail.  As the flexspout is crimped on, it seals the liner to the pail and seals the spout to the pail also.  There is also a small hole in the side of the pail (drum).  As the liquid fills the pail, it forces out trapped air between the liner and the pail.  This pail is used when your product cannot be in an unlined pail and may not be compatible with a baked on steel pail lining.  Water treatment chemicals and corrosive liquids are frequently shipped in this type of pail.
