Samples for testing should be carefully collected at random from the outside of the wrapper sheets from any three sides of the bale and properly handled and stored.

A brushing or scraping procedure is also detailed for determining the amount of bale coating in the outside of the wrapper sheets of smoked sheet rubbers only.
