Signification et objectif
5.1 The tensile properties measured by this method are valuable for studying the behaviour of coatings under environmental stresses such as those arising from ageing and weathering. (See references (1-10).) 4

5.2 Tensile properties may vary with specimen thickness, preparation method, spacing, rate of load application, response of tensile tester and type of fixture used. Donc, these factors need to be carefully controlled if precise comparative results are required.

ASTM D2370-16-2021 Méthode d'essai standard pour les propriétés de traction des revêtements organiques

Champ d'application
1.1 This test method covers the determination of elongation, tensile strength and stiffness (module d'élasticité) of organic coatings when tested as free films.

1.2 Values expressed in SI units are treated as standard values. The values given in parentheses are mathematical conversions of inch-pound units and are for reference only and are not considered standard values.

1.3 Cette norme n'est pas destinée à traiter tous les problèmes de sécurité, si seulement, associé à son utilisation. Il est de la responsabilité des utilisateurs de cette norme d'établir des mesures de sécurité appropriées., pratiques sanitaires et environnementales et pour déterminer l’applicabilité des restrictions réglementaires avant utilisation.
