However, under certain circumstances, simulated or dummy contents may be used on condition that the dimensions and physical properties of such contents shall be as close as possible to those of the intended contents. Ensure

If simulated or dummy contents are used, ensure that the normal method of closure is still employed. 1 CEN EN+28768 92 H BS 4826 : Part 14 : 1987 6 Conditioning The package shall be conditioned in accordance with one of the con
