4.4.3 Rigid bottom and sides examination. Visually verify and measure that the bottom of the
insulating case is made of a rigid material. This material shall extend upward from the bottom
along the front, back and sides for a distance of at least 1 1/2 inches.
4.4.4 Durability test. Prepare a platform 4 feet from ground level. Fill the 5-gallon water can
and insert into the insulating case and place on the platform. The insulated case shall be dropped
3 times from this height. Remove the water can and visually inspect the case to verify that the
inside and outer materials are not damaged.
4.4.5 Identification marking inspection. Visually inspect that the required identification
marking is complete and accurate. Verify that all markings are legible, well-defined and
characters are 1/4 inch in height. The contractor shall certify that the marking medium used is
durable.
4.4.6 Special marking inspection. Visually inspect that the "US" marking is on both sides of
the outside of the case and the letters are at least 1 inch in block form. The contractor shall
certify that the marking medium used is durable.
4.4.7 Environmental requirements certification. The contractor shall certify that the
insulated case with full 5-gallon water can is functional at ambient temperatures of - 400 F to
1250F.
4.4.8 Interface and interoperability requirements examination. Verify, by measuring, that
the 5-gallon water can fits snugly inside the insulated case. With the water can inserted inside the
case, there shall be no more than 1/4 inch distance from the outside surface of the water can to the
inside surface of the insulation. Measurements shall be taken with the cover open, at top front,
top back and top sides. When measuring, the opposite side shall be touching the inside of the
insulation, e.g., if measuring the front, the back side of the water can shall be touching the back
inside edge of the insulation. Repeat this procedure for measuring back and sides.
