适用范围

This Gulf Standard specifies a method for the determination of the percentage of hydrochloric-acid insoluble extraneous silica particles, especially particles of sand, in tobacco (whole leaf, cut tobacco, tobacco scraps and dust) and tobacco products. It is particularly useful to know the proportion of these residues, in the following circumstances: - ?when buying tobacco leaves, in order to check the cleanness; - ?before processing tobacco and tobacco products.
