2. lintels of which the tensile parts are made on site;

3. timber lintels;

4. natural stone lintels, not reinforced.

Linear components spanning clear openings greater than 4,5 m in masonry walls and linear components intended for use independently in a structural role (e.g. beams) are not covered by this standard.
