SCHUMANN, W. A.. Leak tightness and a proposed method for inhibiting water penetration of semi-tight containers. R&D j. (Matieland, Online) [online]. 1990, vol.6, pp.20-25. ISSN 2309-8988.

A practical way of characterising semi-tight containers in terms of a leak constant is suggested. In order to distinguish between vacuum-tight, semi-tight and open containers limits for the leak constant are established. A solution for infiltration of water into semi-tight containers is discussed and used for defining the maximum limit of the leak constant.
