This British Standard describes a method for monitoring the levels of certain residual volatile solvents in unprinted and gravure or flexographic printed papers, films, foils and laminates intended for packaging.
The method is suitable for monitoring the presence of at least the following solvents:
| acetone | 2-ethoxy-ethanol |
| tetrahydrofuran | isopropanol |
| N-propanol | isopropyl acetate |
| toluene | ethyl acetate |
| ethanol | methyl ethyl ketone (butanone) |
| N-propyl acetate | isobutanol |
NOTE 1. Methyl ethyl ketone and tetrahydrofuran have very similar retention times and cannot be resolved by this method. However, the presence of both solvents in any one sample rarely occurs.
NOTE 2. The titles of the publications referred to in this standard are listed on the inside back cover.
