5.1 This test method provides a quantitative measure of the pressure-sensitive tack of the adhesive.5.2 The method is designed for the adhesive mass itself and is suitable for measuring the tack of pressure-sensitive adhesives for use on both rigid and flexible backings.5.3 This test method is suitable for quality control and research purposes.1.1 This test method covers measurement of the pressure-sensitive tack of adhesives. This test method is applicable to those adhesives which form a bond of measurable strength rapidly upon contact with another surface and which can be removed from that surface cleanly, that is, without leaving a residue visible to the eye. For such adhesives, tack may be measured as the force required to separate an adhesive and the adherend at the interface shortly after they have been brought into contact under a defined load of known duration at a specified temperature.1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

4.1 Procedure A measures the ability of a pressure-sensitive tape to adhere to a standard steel panel under constant stress. This may or may not relate to the ability of the tape to adhere to other surfaces.4.2 Procedures B, C, and D may be used to determine the shear adhesion of the tapes generally used to close fiberboard boxes in packaging applications.4.3 Procedure D measures the shear adhesion of a pressure-sensitive tape to a nonstandard fiberboard, liner board, corrugated board, or other surfaces which is agreed upon for testing. This may be used to compare the shear adhesion of a tape to a particular fiberboard surface or to compare the shear adhesion of a tape to a variety of fiberboard surfaces.4.3.1 The surfaces of similar fiberboards may exhibit considerable variation between mills, between batches from one mill, and within batches. Take care in the choice of samples and when comparing results between fiberboard surfaces which may not be exactly the same.4.3.2 The precision of tests conducted on nonstandard surfaces may be different than that described in Section 13.4.4 Procedures E, F, and G may be used to determine the ability of a filament reinforced tape to hold when placed under constant stress.4.5 Procedure H may be used to compare the shear adhesion of tape applied to a standard steel surface and tested at an elevated temperature. The use of an elevated temperature during test tends to reduce the duration of the test.1.1 This test method covers procedures for determining the ability of pressure-sensitive tapes and labels to remain adhered under constant load applied parallel to the surface of the tape and substrate.1.1.1 Procedure A measures the shear adhesion when applied to a vertical standard steel panel.1.1.2 Procedure B measures the shear adhesion when applied to vertical panel covered with NIST SRM 1810A standard fiberboard.1.1.3 Procedure C measures the shear adhesion when applied to a vertical panel covered with a fiberboard as defined by Comite Europeen de Normalisation (CEN).1.1.4 Procedure D measures shear adhesion when applied to a vertical panel covered with a fiberboard agreed upon by the buyer and seller.1.1.5 Procedure E measures shear adhesion of filament reinforced tape when applied to a horizontal standard steel panel.1.1.6 Procedure F measures shear adhesion of a filament reinforced tape when applied to a horizontal panel covered with NIST SRM 1810A standard fiberboard.1.1.7 Procedure G measures the shear adhesion of a filament reinforced tape when applied to a horizontal panel covered with a standard fiberboard defined by CEN.1.1.8 Procedure H measures the shear adhesion the same as Procedure A except the test is conducted at an elevated temperature and after a 10-min dwell time at the elevated temperature.1.2 These procedures provide a means of assessing the uniformity of the adhesive of a given type of pressure-sensitive tape, usually tapes used for packaging applications. The assessment may be within a roll of tape, between rolls or production lots.1.2.1 Variations in the tape backing and adhesive affect the response; therefore, these procedures cannot be used to pinpoint the specific cause(s) of nonuniformity.1.2.2 This test method is intended to replace AFERA 4012, CEN 1943, and PSTC (see 7.2).1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems will result in non-conformance with the standard.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

6.1 This guide is designed to assist the forensic tape examiner in selecting and organizing an analytical scheme for the analysis, comparison, and identification of tapes. The size and condition of the sample(s) influences the choice of analytical scheme. The evaluation and interpretation of the data for each technique is an important part of an analytical scheme but it is outside the scope of this guide. These will be addressed in other ASTM standards.1.1 This guide is intended as an introduction to other standard guides for the forensic examination of pressure sensitive adhesive tape. It is intended to assist individuals who conduct forensic tape analyses in their evaluation, selection, and application of tests that can be of value to their examinations. This guide describes the construction and classification of various tapes and the methods to develop discriminatory information using an efficient order of testing. This standard provides an overview and guidance on the strengths and limitations of various techniques used in the analysis and comparison of pressure sensitive adhesive tapes. The goal is to provide a consistent approach to forensic tape analysis.1.2 The forensic tape examiner addresses concerns such as sample size, complexity and condition of the sample, environmental effects, collection and packaging methods, and case/investigation specific issues. These factors require that the forensic tape examiner choose test methods, sample preparation schemes, testing sequences, and degree of sample alteration and consumption that are suitable to each specific case.1.3 This standard is intended for use by competent forensic science practitioners with the requisite formal education, discipline-specific training (see Practice E2917, Practice E3233), and demonstrated proficiency to perform forensic casework.1.4 The values stated in SI units are to be regarded as standard. Other units of measurement are included in this standard as applicable to industrial usage.1.5 Some of the methods discussed in this guide involve the use of chemicals, temperatures, and radiation sources. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
