4.1 Procedure A measures the ability of the pressure-sensitive tape to adhere to a standard steel plate under constant stress. This may or may not involve the tape’s ability to adhere to other surfaces.
4.2 Procedures B, C and D may be used to determine the shear adhesion of tape commonly used to seal fiberboard boxes in packaging applications.
4.3 Procedure D measures the shear adhesion of pressure-sensitive tape to non-standard fiberboard, lining board, corrugated cardboard or other tested agreed surfaces. This can be used to compare the shear adhesion of the tape to a specific fiberboard surface or to compare the shear adhesion of the tape to various fiberboard surfaces.
4.3.1 The surface of similar fibreboard may exhibit significant differences between mills, between batches of a mill, and within batches. Be careful when selecting samples and when comparing results between fiberboard surfaces (which may not be exactly the same).
4.3.2 The accuracy of tests performed on non-standard surfaces may differ from that described in Section 13.
4.4 Procedures E, F and G may be used to determine the holding capacity of the filament reinforced tape under constant stress.
4.5 Program H can be used to compare the shear adhesion of the tape on a standard steel surface and to test it at high temperatures. Using elevated temperatures during testing tends to reduce test time.
ASTM D3654/D3654M-2019 Standard Test Method for Shear Adhesion of Pressure-Sensitive Tape
Крок 1: Область застосування
1.1 This test method covers procedures for determining the ability of pressure-sensitive tapes and labels to maintain adhesion under constant loads parallel to the tape and substrate surfaces.
1.1.1 Program A measures shear adhesion when applied to vertical standard steel plates.
1.1.2 Procedure B measures shear adhesion when applied to a vertical panel covered with NIST SRM 1810A standard fiberboard.
1.1.3 Program C measures the shear adhesion when applied to a vertical panel covered with fiberboard as defined by Comite Europeen de Normalization (CEN).
1.1.4 Procedure D measures the shear adhesion on a vertical panel covered with fiberboard as agreed by the buyer and seller.
1.1.5 Procedure E measures the shear adhesion of filament reinforced tape when pasted to a horizontal standard steel plate.
1.1.6 Program F measures the shear adhesion of filament reinforced tape when added to a horizontal board covered by NIST SRM 1810A standard fiberboard.
1.1.7 Program G measures the shear adhesion of filament reinforced tape when added to a horizontal board covered with standard fiberboard as defined by CEN.
1.1.8 Program H measures the shear adhesion in the same way as Program A, except that the test is performed at high temperatures and after 10 minutes at high temperatures.
1.2 These procedures provide a way to evaluate the adhesive uniformity of a given type of pressure-sensitive tape (typically for packaging). Evaluation can take place within a roll of tape, between rolls or between production batches.
1.2.1 Changes in tape backing and adhesive will affect the response; глибина занурення ротора в рідину і вплив бульбашок. Роторний віскозиметр має суворі вимоги до глибини занурення ротора в рідину і повинен експлуатуватися відповідно до інструкцій, these procedures cannot be used to identify specific causes of non-uniformity.
1.2.2 This test method is intended to replace AFERA 4012, CEN 1943 and PSTC (побачити 7.2).
ASTM D3654/D3654M-2019 Standard Test Method for Shear Adhesion of Pressure-Sensitive Tape
1.3 Values expressed in SI units or inch-pound units shall be treated as standards separately. The values specified in each system are not exactly the same; глибина занурення ротора в рідину і вплив бульбашок. Роторний віскозиметр має суворі вимоги до глибини занурення ротора в рідину і повинен експлуатуватися відповідно до інструкцій, each system should be used independently. Combining the values of the two systems results in non-compliance.
1.4 This standard is not intended to address all safety concerns associated with its use. Користувачі цього стандарту несуть відповідальність за встановлення належної безпеки, health and environmental specifications and to determine the applicability of regulatory restrictions prior to use.
1.5 Цей міжнародний стандарт базується на міжнародно визнаних принципах стандартизації, встановлених у Рішенні про принципи розробки міжнародних стандартів, Керівні принципи та рекомендації, видані СОТ щодо технічних бар'єрів у торгівлі (TBT) Комітет.
