3.1 Poor adhesion of ink or coating to the base substrate can impact the readability of printed materials, affect the functionality of coated materials, or create a source of contamination. This practice provides a means for evaluating the adhesion of ink or coating to a flexible packaging material.3.2 For purposes of resolving inter-laboratory disagreements, test methods developed from this practice may be improved by defining and controlling the pressure and method of tape application, (for example, using weighted roller), and the speed and angle of tape removal.3.3 This practice does not address acceptability criteria. These need to be jointly determined by the user and producer of the product.1.1 This practice describes a means of evaluating ink or coating adhesion to flexible packaging materials. This practice is intended for use on flexible packaging materials whose surfaces are not damaged by the application and removal of tape.1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.1.3 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.

3.1 The procedures outlined herein are grounded in the generally accepted body of knowledge and experience in the field of forensic tape examination and comparison.3.2 With successful completion of this tape analysis training program, the trainee gains the theoretical knowledge and practical skills necessary to perform, document, and evaluate forensic tape examinations and comparisons.3.3 This training practice covers a variety of instrumental methods which can be used in the analysis of tape. Not all laboratories will have access to all of the instrumentation. It is expected that a tape analysis training program will include all the techniques that are found within a laboratory’s procedures for the forensic examination of tape.3.3.1 Instrumental methods that provide organic and inorganic analysis capabilities are utilized in the laboratory training program. Examples include Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, pyrolysis gas chromatography (PGC), scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM/EDS), X-ray fluorescence (XRF), or X-ray diffraction (XRD).1.1 This standard is intended as a practice for use by laboratory personnel responsible for training examiners to perform forensic examinations and comparisons on pressure sensitive tapes and adhesives. It contains a list of training objectives with recommended methods of instruction, reading assignments and structured exercises to provide practical experience for the trainee.1.1.1 The trainees and training program shall meet or exceed the minimum training requirements set forth in Practice E2917.1.1.2 Additional training could be required for a particular method or instrument referred to herein. The application of analytical techniques to tape analysis assumes the trainee is already competent in the use of each particular analytical technique or instrumental method.1.1.3 Other sources of information on forensic tape examination not specifically mentioned in this document can be considered and added.1.1.4 Additional tape analysis training beyond that which is listed here should be made available to the trainee. Such training could include off-site courses, internships, and specialized training by experienced examiners.1.1.5 Continuing education and training is recommended. Additional training provides a forensic tape examiner with the opportunity to remain current in the field.1.1.6 Tape samples are evaluated for physical matches of the cut or torn end pieces. This practice does not provide training requirements for physical match comparisons. Additional training is required to conduct this type of analysis.1.2 This practice is in a modular format for easy adaptation to an individual laboratory’s training program. Recommendations as to lessons, practical exercises, progress monitoring, and trainee evaluations are included. Reading assignments are listed in each subsequent section of this practice; full citations are available in the References section.1.3 A tape analysis training program provides a theoretical foundation and basic practical skills necessary to prepare a trainee to become a qualified forensic tape examiner. At the end of the tape analysis training program, the trainee is capable of forming opinions based upon sound scientific knowledge, appropriate examinations, and practical experience. The trainee also is able to independently work cases, write reports, testify in court, and peer review cases. Upon completion of the program by a trainee or at some regular interval (for example, once per accreditation cycle), the training program should be evaluated for its efficacy and relevance according to the guidance set forth in Practice E2917.1.4 This practice does not address human factors (for example, cognitive bias). It is the responsibility of the user of this practice to address human factors during the initial or general training of a forensic scientist.1.5 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.

5.1 These test methods are tools for quality assurance use. Given specific pressure-sensitive tape and a requirement in terms of the minimum or maximum peel value expected for this tape, the data from the test can be used in conjunction with acceptance criteria.5.2 Test Method A, B, C, E, or F can show the relative bond strength of a given tape to one or more surfaces (material and texture) as compared to the standard stainless steel panel. Substitution of representative samples of materials in question for the standard steel panel would suffice to do this.5.3 Test Methods A, B, C, E or F cannot be used to compare two pressure-sensitive tapes of the same type but of different manufacture for their ability to adhere to a surface. This is because the measured peel force is not normalized for a fixed area of stress. The area under stress varies with backing stiffness and adhesive rheology (firmness). Two different tapes seldom agree in these properties.5.4 Test Method D can show the amount of force required to remove a liner that covers the adhesive side of a tape at a specified peel rate. The force will be different at other peel rates.5.5 These test methods may not provide design information as there is usually no direct relationship between peel adhesion and any functional requirement.1.1 These test methods cover the measurement of the peel adhesion of pressure-sensitive tapes.1.1.1 Test Method A gives a measure of the adherence, when peeled at 180° angle, to a standard steel panel or to other surface of interest for a single-coated tape.1.1.2 Test Method B gives a measure of the adherence to the backing of a single-coated tape.1.1.3 Test Method C gives a measure of the adherence of double-coated tape to a standard steel panel or other surface of interest.1.1.4 Test Method D gives a measure of the adherence of the release liner to the adhesive of either single- or double-coated tape.1.1.5 Test Method E gives a measure of the adherence of an adhesive transfer tape to a standard steel panel or other surface of interest.1.1.6 Test Method F gives a measure of the adherence, when peeled at 90° angle, to a standard steel panel or other surface of interest for a single-coated tape.1.2 These test methods provide a means of assessing the uniformity of the adhesion of a given type of pressure-sensitive adhesive tape. The assessment may be within a roll of tape, between rolls, or between production lots.1.3 Variations in either the tape backing or the adhesive, or both, affect the response. Therefore, these test methods cannot be used to pinpoint the specific cause(s) of non-uniformity.1.4 These test methods may not be appropriate to test tapes having relatively stiff backings, stiff liners, or backings showing high stretch at low forces. These characteristics will result in a high variability for the test response which is not a true indication of the real nature of the adhesive bond.1.5 Values stated in either SI or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents, therefore, each system must be used independently without combining values in any way.1.6 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.1.7 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.
