משמעות ושימוש
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, כְּלוֹמַר. the material is not cut into a sample width less than the received width. בדרך כלל, tapes wider than 48 מ"מ [2 in] are not tested, mainly due to equipment limitations. Tape that is about 3 מ"מ [0.125 in] 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.

שלב 1: תְחוּם
1.1 This test method covers the measurement of the breaking tensile strength (breaking strength) and tensile properties (הַאֲרָכָה) 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 (” ו “value) 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. ייתכן שהערכים המצוינים בכל מערכת אינם זהים לחלוטין; The conversion between measurement systems needs to be done carefully.

1.3 This standard is not intended to address all safety concerns associated with its use. באחריות המשתמשים בתקן זה לבסס בטיחות מתאימה, health and environmental specifications and to determine the applicability of regulatory restrictions prior to use.

1.4 תקן בינלאומי זה מבוסס על עקרונות תקינה מוכרים בינלאומיים שנקבעו בהחלטה על עקרונות לפיתוח תקנים בינלאומיים, Guidelines and Recommendations issued by the WTO Technical Barriers to Trade (TBT) Committee.
