7.2.1 The size of the container shall correspond to the
required amount of sample.
8. Protection and Preservation of Samples
8.1 Sample containers shall be new. They shall not be
washed or rinsed, or wiped with an oily cloth. If they contain
evidence of solder flux, or if they are not clean and dry, they
shall not be used. Top and container shall fit together tightly.
8.2 Care shall be taken to prevent the sample from becom-
ing contaminated. Immediately after filling, the container shall
be tightly and positively sealed.
8.3 The filled sample container shall not be submerged in
solvent, nor shall it be wiped with a solvent saturated cloth. If
cleaning is necessary use a clean d
