sample  that  is representative    of a cross  section  of the material  in the container   to a depth  of at least  152 mm (6 in.).  Take precautions   during  the sampling  operation  to avoid  exposing  the

sample  unduly  to atmospheric   moisture.  Immediately   and thoroughly  mix the individual samples  to form  a representative    composite  sample  of material  and store  in a sealed  glass  or suitable  plastic  container.
