Signification et utilisation
5.1 The information provided by this test method can be used for material specifications for product design and quality assurance applications. Can be used to compare different products.

5.2 The use of the test method must be related to the test purpose. One purpose is to determine the relative strength of the tape at the time of purchase or use. Another aim is to identify or characterize a specific backing material.

5.2.1 The test may be performed on the received tape, c'est à dire. the material is not cut into a sample width less than the received width. En général, tapes wider than 48 mm [2 dans] are not tested, mainly due to equipment limitations. Tape that is about 3 mm [0.125 dans] narrow can be tested.

5.2.2 Tests may be performed on samples cut within the boundaries of the sample material using a sharp razor, such as the blade defined in Section 6. This method is commonly used for material characterization, determining consistent quality, and conforming to specifications.

5.3 Elongation at break or tensile properties up to a specified elongation may be related to the intended use of the tape or to its use in identifying or characterizing the material.

ASTM D3759/D3759M-2019 “Standard Test Method for Breaking Strength and Elongation of Pressure Sensitive Tape”

Étape 1: Portée
1.1 This test method covers the measurement of the breaking tensile strength (breaking strength) and tensile properties (élongation) of pressure-sensitive tapes and labels. It includes programs for machine orientation and transversal, high strength filament reinforced backing and high elastic backing. It also includes the process of obtaining the force (” F “valeur) of the specified elongation. These programs use a constant rate of expansion (CRE) type test machine.

1.2 Values expressed in SI units or inch-pound units shall be regarded as standard values respectively. Les valeurs spécifiées dans chaque système peuvent ne pas être exactement les mêmes; The conversion between measurement systems needs to be done carefully.

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

1.4 Cette norme internationale est basée sur les principes de normalisation internationalement reconnus établis dans la Décision sur les principes pour l'élaboration de normes internationales., Lignes directrices et recommandations émises par l'OMC Obstacles techniques au commerce (OTC) Comité.
