Etudes comparativesIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : It has long been accepted that high correlation exists between the tearing loads obtained from the Baumann tear test (IUP/8) and tha ALCA test E 10, slightly modified by SATRA and designated PM 30. Recently, however, the tearing energy has been put forward as a better criterion of tear resistance. The work described in this paper has therefore been concerned primarily with comparing various tearing criteria for the two test specimen shapes. It is concluded that the tearing energies obtained from the two tests correlate well with each other, although some semichrome leathers are anomalous.

Technologie -- Moyen âgeIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : The paper is a descriptive account of work undertaken to re-create medieval leathers for use in an exercise in experimental archaeology—namely the Brendan voyage 1976-77. Leather for the boat's hull was made from oak-tanned ox hide impregnated with wool grease; it contained 35% dichloromethane extractables (IUC/4), had a water absorbtion (IUP/7) of 14% after 72 h, and resisted penetration by 3.5 % saline for more than 2000 h (IUP/1 1). The wooden frame was lashed together with alum tanned laces, which had a wet-breaking load of 45 kg. The transatlantic voyage of 4500 miles was completed in two stages and took 111 days (85 days at open sea), the hull leather retained its structural stability and initial water resistance.
