Standard Test Method for Curling, Twisting, and Tubing on Unwind of Pressure-Sensitive Tapes

Standard Test Method for Curling, Twisting, and Tubing on Unwind of Pressure-Sensitive Tapes

SIGNIFICANCE AND USE
This test method will provide information on the relative tendency of tapes to curl, twist, or form into a tube with touching edges. The amount of each is a predictor of the difficulty one might experience in handling strips of tape of any length during their application.
There are several causes for variation in the extent or degree of these characteristics and may vary themselves within a production lot of tape. Therefore, it is essential to use an accepted sampling plan (see Section 7) when it is desired to use this test method to compare two types of tape for acceptance sampling purposes.
SCOPE
1.1 This test method provides one procedure for determining the extent of curling, the degree of twisting, and tendency to form a tube resulting from unwinding of the tape from its roll.
1.2 The 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.
1.3 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.

Standard Test Methods for Loop Tack

SIGNIFICANCE AND USE
5.1 These test methods provide a quantitative measure of the pressure-sensitive tack property of an adhesive.
FIG. 1 Loop Tack Test Fixture 1  
FIG. 2 Loop Tack Test Fixture 2  
FIG. 3 Loop Tack Sample During Test  
5.2 These test methods are designed to measure the tack property of the adhesive mass. The tack of a given adhesive varies depending on the backing (generally, stiffer backings lead to higher values).  
5.3 Theses test methods are suitable for quality control and research purposes.  
5.4 Test Method A (using Tensile Tester) makes use of a specimen strip 7 in. (175 mm) in length. Both the FINAT FTM 9 “Quick Stick” Tack Measurement Test and the TLMI L-IB2 Tensile Tester Loop Tack Test also use a specimen strip of that length.  
5.5 Test Method B (using Loop Tack Tester) makes use of a specimen strip five in. (125 mm) in length. That is the only length specimen strip that fits properly in the loop tack tester.  
5.6 If the adhesive is not already otherwise coated, these test methods incorporate the use of a clear 2 mil (0.05 mm) polyester (PET) film backing for specimen preparation. Use of other backing materials changes performance of the specimen to be tested.
SCOPE
1.1 These test methods cover the determination of properties of a pressure-sensitive adhesive. These test methods are applicable to those adhesives that form a bond of measurable strength rapidly upon contact with another surface. Tack force may be measured as the force required to separate the adhesive from the adherend at the interface shortly after they have been brought into contact under a load equal only to the weight of the pressure-sensitive article (for example, tape, label, sticker, etc.) on a 1 in.2 contact area.  
1.2 The following test methods are included:  
1.2.1 Test Method A (using Tensile Tester), and  
1.2.2 Test Method B (using Loop Tack Tester).  
1.3 The values stated in inch-pound units are to be regarded as the standard because the industry standard width for pressure-sensitive tape is 1 inch. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered 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.

ASTM D5570/D5570M-10(2022)(Test Method)
Standard Test Method for Water Resistance of Tape and Adhesives Used as Box Closure

SIGNIFICANCE AND USE
5.1 When a box becomes wet, the performance of the box and its closure are reduced. It is desirable to have box closure methods that retain an ability to keep the box closed when wet. Sealing or reinforcing methods sometimes are useful to improve performance of wet boxes and closures. Water resistance is sometimes a regulatory or contractual requirement.  
5.2 A test result indicating that a box closure tape or adhesive is soluble or dispersible in water is an indication that its function will be significantly impaired when wet. A test result that does not indicate solubility or dispersibility does not necessarily ensure that the bonding ability will be satisfactory when wet or that the performance of the box closure will be satisfactory when wet. Package performance testing described in the water resistance section of Practice D1974 is useful to further investigate the effects of water on package and closure functions.
SCOPE
1.1 This test method covers a procedure to determine the water resistance of an adhesive or tape as measured by the amount of tape or adhesive dissolved or dispersed in water.  
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 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.  
1.4 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.

ASTM D3811/D3811M-21a(Test Method)
Standard Test Method for Unwind Force of Pressure-Sensitive Tapes

SIGNIFICANCE AND USE
5.1 This procedure simulates hand and machine unwinding of tape at low rates. The force required for unwinding at low rates is a function of rate. At some rate (expected to be different for each construction type and manufacturer) there occurs an inversion of the response. The rate for this test method does not allow for comparisons of different tapes that will be unwound at high rates.  
5.2 This procedure can be used to indicate satisfaction where a specification for unwind; either maximum, minimum, or mean; is established and when the responses referred to in 5.1 are taken into consideration.
SCOPE
1.1 This test method covers one procedure for determining the force required to unwind a roll of pressure-sensitive tape.  
1.2 The 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.  
1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Standard Test Method for Thickness of Pressure-Sensitive Tapes

SIGNIFICANCE AND USE
4.1 Thickness is an important property of tapes, and this dimension is important for certain end uses. This test method is useful for quality control and for acceptance testing for conformance to specifications.
SCOPE
1.1 This test method covers the determination of the thickness of pressure-sensitive tapes at standard conditions.  
1.2 This test method is intended to replace AFERA 40062 and PSTC 33.2  
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 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.

Standard Test Method for Time to Failure of Pressure Sensitive Articles Under Sustained Shear Loading

SIGNIFICANCE AND USE
5.1 This test method measures the cohesive strength of the adhesive on a pressure sensitive article. The time to failure can predict end use properties of pressure sensitive articles such as edge ooze from cold flow; trimming, slitting and die cutting quality; telescoping in tapes; ability to seal packages; and vertical holding power.  
5.2 This test method is suitable for quality control, development and applications testing.  
5.3 If the adhesive is not already coated, the adhesive can be coated on smooth, clear polyester (PET) film backing 0.05 mm [0.002 in.] thick. The recommended dry adhesive thickness is 0.025 mm [0.001 in.].  
5.4 Humidity has a strong effect on time to failure for many pressure sensitive articles. Therefore, humidity should be controlled in accordance with 8.1.2.
SCOPE
1.1 This test method covers the ability of a pressure sensitive article (for example, tape, label, sticker, etc.) to remain adhered to a stainless steel panel under a constant load applied parallel to the bonding surface of the pressure sensitive article.  
1.2 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.  
1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
