5.1 The quantities of mineral aggregate adhered to the surface of a roof vary with the characteristics and total amount of the aggregate. Mineral aggregate shields bituminous membranes from solar radiation. Unadhered mineral aggregate can be displaced by wind, water, and traffic, exposing the bitumen.5.2 This test method provides a laboratory means of determining and recording the mass of aggregate that adheres to a bituminous pour coat.1.1 This test method determines the adhesion of mineral aggregate when applied over a pour coat of hot bitumen on a roof membrane.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.

4.1 This test method provides a standard method to bend the product to verify good coating, adhesion free of delamination, on metallic-coated steel sheet products under the jurisdiction of ASTM Committee A05 and its subcommittees as designated by a purchaser in a purchase order or contract.4.1.1 Metallic coated coupons are bent 180° around progressively more thicknesses of metal, the end point being when failures no longer occur. The bend area is examined without magnification after each bend in order to determine coating fracture and loss of adhesion.4.1.2 If desired, further examination of loss of adhesion or pickoff can be determined by performing a tape pull-off test subsequent to bending.4.1.3 The material condition at the time of testing, sampling frequency, specimen location and orientation, minimum t-bend rating exhibiting no delamination or pick-off, reporting requirements, and other test parameters are contained in the pertinent material specification or in a general requirement specification for the particular product form. References are provided to the appropriate ASTM standards.4.2 For this test method to successfully evaluate coating adhesion, the metal substrate must be capable of withstanding the bending operation without fracturing.4.3 Coating adhesion is a significant quality characteristic of metallic coated steel sheet products. This test method employs the relevant t-bend rating specified in the referenced product standards to quickly determine if the metallic coating is free of delamination on the outside of a bend specimen. This is critical in ascertaining product conformance to specifications.4.4 This test method is similar to, and uses some of the same apparatus as, Test Method D4145, which determines a t-bend rating for flexibility and adhesion of organic coatings (paints) on metallic substrates.4.5 This test method may be used by other ASTM Committees and other standards writing bodies for the purpose of conformance testing.1.1 This test method covers a bend test to verify that metallic coatings on steel sheet are free of delamination. The test method described is designed and intended for use in both laboratory and plant situations and their environments.1.2 The metallic-coated steel product shall conform to all the requirements of the appropriate specifications as follows: Specifications A463/A463M, A653/A653M, A755/A755M, A792/A792M, A875/A875M, A924/A924M, A929/A929M, A1046/A1046M, A1057/A1057M, A1063/A1063M, A1079, and A1087/A1087M.1.3 Quantitative limits are not addressed and are established in the general requirements, or individual product specifications, or both; or when applicable, as agreed to between supplier and user.1.4 Units—This specification is applicable to orders in either inch-pound units or SI units. Values in inch-pound and SI units are not necessarily equivalent. Within the text, SI units are shown in brackets. Each system shall be used independently of the other.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.

3.1 These test methods are designed primarily for specimens prepared in a laboratory under standardized conditions such as may be used to provide data for development and control of rubber compounds and methods of manufacture. With slight modifications as indicated, Methods A, B, C, D, and E are also used for obtaining comparative adhesion test values of production parts whenever the design permits preparation of suitable test specimens. Methods A, B, C, and D are applicable in the case of many products in which rubber is used for controlling vibration.1.1 These test methods cover procedures for testing the static adhesional strength of rubber to rigid materials (in most cases metals).Method A—Rubber Part Assembled Between Two Parallel Metal Plates.Method B—90° Stripping Test—Rubber Part Assembled to One Metal Plate.Method C—Measuring Adhesion of Rubber to Metal with a Conical Specimen.Method D—Adhesion Test—Post-Vulcanization (PV) Bonding of Rubber to Metal.Method E—90° Stripping Test—Rubber Tank Lining—Assembled to One Metal Plate.Method F—Rubber Part Assembled Between Two Parallel Convex-Shaped Metal PlatesMethod G—Measuring Bond Durability for Rubber-to-Metal Bonded Components with a Double Shear Cylindrical SpecimenMethod H—Measuring Bond Durability for Rubber-to-Metal Bonded Components with a Quadruple Shear Specimen1.2 While the test method may be used with a wide variety of rigid materials, use of materials other than metals is the exception. For this reason, we have used the word “metal” in the text rather than “rigid materials.”1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.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.

4.1 This test method is designed as a screening test in the evaluation of coating systems and other materials designed to resist biofouling attachment.4.2 The degree and type of barnacle fouling will vary according to the geographic location of test sites and the time of year when tests are implemented. Surfaces with known barnacle adhesive shear strength should be exposed to provide comparative data.1.1 This test method covers the measurement of barnacle adhesion in shear to surfaces exposed in the marine environment. It is used to establish the ability of a surface to reduce biofouling adhesion. Surfaces with known barnacle adhesion strengths are included to serve as controls.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, 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.

5.1 There are differences in opinion among those concerned with sealant technology whether or not this adhesion-in-peel test simulates the type of strain and e-tensile stresses encountered by a sealant in normal use. Nevertheless, this test provides a valuable measurement of the ability of the cured sealant to maintain a bond to the substrate under severe peel conditions.5.2 Many sealant manufacturers utilize the adhesion-in-peel test for determining the adhesive characteristics of sealant/primer combinations with unusual or proprietary substrates. This test is especially useful for quality measurements comparing batches of the same sealant relative to adhesion or for studying adhesion of a given sealant to a variety of substrates.5.3 This test method alone is not appropriate for comparing the overall performance of different sealants in a given application. The adhesive force that determines if a given sealant is useful in a given application also depends on the modulus of elasticity and the degree to which the sealant will be strained. This test, as it exists, does not consider the modulus of elasticity, nor amount of stress that will be produced by a given strain in an actual sealant in a moving joint. No known correlations are given to relate and apply modulus values to the peel values.5.4 This test requires that the results indicate whether the failure mode is primarily adhesive or cohesive. It is important to note that a cohesive failure is not necessarily better than an adhesive failure, if the adhesive value is sufficient for the application. Having adhesive failure allows one to study the change of adhesion with time and with the various stress conditions.1.1 This test method covers a laboratory procedure for determining the strength and characteristics of the peel properties of a cured-in-place elastomeric joint sealant, single- or multicomponent, for use in building construction.1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.1.3 The committee with jurisdiction over this standard is not aware of any comparable standards published by other organizations.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.

5.1 When the test is performed on the repair or overlay material, the result is the bond strength to the concrete panel or the tensile strength of either the overlay or concrete panel, whichever is weaker.5.2 The measured strength is controlled by the failure mechanism requiring the least stress. Thus, it is not possible to know beforehand which strength will be measured by the test. For this reason, the failure mode has to be reported for each individual test result, and tests results are averaged only if the same failure mode occurs. Alternatively, one can infer that the bond strength is greater than the failure stress if the bond does not fail during the test.5.3 The method may also be used to evaluate the performance of bonding agents.5.4 This test method is designed to evaluate bond strengths in the laboratory and to standardize conditions that permit comparison of results between laboratories. It is not intended to determine bond strength for field applications as results obtained are only applicable to the standard substrate.1.1 This test method is suitable for laboratory use to determine one or more of the following:1.1.1 The bond strength of a repair or an overlay material to a specific concrete substrate.1.1.2 The tensile strength of a repair or overlay material after the material has been applied to the concrete substrate.1.1.3 The change in bond strength when applying a bonding agent or other bond modifying treatment to the concrete substrate.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 are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. Some values have only SI units because the inch-pound equivalents are not used in practice.1.2.1 If required results obtained from another standard are not reported in the same system of units as used by this test method, it is permitted to convert those results using the conversion factors found in the SI Quick Reference Guide.21.3 The text of this test method refers to notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this test method.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. (Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.)31.5 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.

5.1 If the ink or coating is to fulfill its function, it must adhere to the substrate. Substrates and their surface preparation have a significant effect on the adhesion of inks or coatings. Therefore, a method of evaluating adhesion of inks or coatings to different substrates or surface treatments, or of different inks or coatings to the same substrate and surface treatment, is useful to the industry.5.2 The limitations of all adhesion methods and the specific limitation of this test method to lower levels of adhesion should be recognized before using it. The intra– and inter–laboratory precision of this test method is under evaluation.5.3 Printing area to be tested should be a solid area large enough to include the entire cross hatch pattern.1.1 This test method is based on existing Test Method D3359, with modifications to make it suitable for flexible substrates, printed electronic devices and membrane switches.1.2 Despite the problems associated with a tape test on plastic substrates, it is our belief that this is still one of the best ways to test ink and coating for adhesion for membrane switch or printed electronic device applications. In writing this test method we are addressing several of the objections to the test method that could affect its precision and repeatability on plastic substrates.1.3 These test methods cover whether the adhesion of coating or ink to a substrate is at an acceptable level. They do not distinguish between higher levels of adhesion, for which more sophisticated methods of measurement may be required.NOTE 1: It should be recognized that differences in adherability of the ink or coating surface can affect the results obtained with inks or coatings having the same inherent adhesion.1.4 In multi–coat systems adhesion failure may occur between coats, so that the adhesion of the coating system to the substrate is not determined.1.5 This test method is specifically designed for measuring adhesion of inks and coatings (films) that have a thickness of 5 mil (125 microns) or less, on plastics such as polyester and polycarbonate.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 and health practices and determine the applicability of regulatory limitations prior to use.

ASTM D6677-18(2022) Standard Test Method for Evaluating Adhesion by Knife Active 发布日期 :  1970-01-01 实施日期 : 

4.1 Coatings, to perform satisfactorily, must adhere to the substrates on which they are applied. This test method has been found useful as a simple means of assessing the adhesion of coatings. Although this method is a qualitative (subjective) test it has been used in industry for many years and can provide valuable information.4.2 Other adhesion test methods may be useful in obtaining quantitative results. See Test Methods D2197, D3359, D4541, and D7234.4.3 The Performance Evaluation Scale (see Table 1) is based on both the degree of difficulty to remove the coating from the substrate and the size of removed coating chip.4.4 This test method does not have a known correlation to other adhesion test methods (pull-off, tape, etc.).4.5 A coating that has a high degree of cohesive strength may appear to have worse adhesion than one that is brittle and hence fractures easily when probed.4.6 This method is not to be used on overly thick coatings, that is, those which cannot be cut to the substrate with a utility knife in one stroke.1.1 This test method covers the procedure for assessing the adhesion of coating films to substrate by using a knife.1.2 This test method is used to establish whether the adhesion of a coating to a substrate or to another coating (in multi-coat systems) is at a generally adequate level.NOTE 1: The term “substrate” relates to the basic surface on which a coating adheres (may be steel, concrete, etc. or other coating).1.3 This method can be used in the laboratory and field.1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.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 The pull-off strength and mode of failure of a coating from a concrete substrate are important performance properties that are used in specifications. This test method serves as a means for uniformly preparing and testing coated surfaces, and evaluating and reporting the results.5.2 Variations in strength results obtained using different instruments, different substrates, or different loading fixtures with the same coating are possible. Therefore, it is recommended that the specific test instrument and loading fixture be mutually agreed upon between the interested parties.5.3 It is recommended that the coating be sufficiently cured to ensure cohesive strength and adhesion. This required minimum cure time before testing should be provided by the coating manufacturer, and may require an extension due to atmospheric conditions on site (for example, low temperature, and low or high humidity).5.4 This test method may be adapted to determine surface strength of uncoated concrete (see X2.1). Test Method C1583 is also suitable for that determination.5.5 The objective of this method is to determine the adhesion of a coating to concrete (or adapted for surface strength as stated in 5.4) and will result in failure in the coating or near the substrate surface. If evaluating the cohesive strength of the substrate or cementitious surfacers is the purpose of the testing, or if the substrate or cementitious surfacers have low strength, then Test Method C1583 may be more suitable.1.1 This test method covers procedures for evaluating the pull-off strength of a coating on concrete. Pull-Off strength of coatings for other rigid substrates is described in Test Method D4541. The test determines the greatest perpendicular force (in tension) that a surface area can bear before a plug of material is detached. Failure will occur along the weakest plane within the system comprised of the loading fixture, glue, coating system, and substrate, and will be exposed by the fracture surface.1.2 This test method uses a class of apparatus known as portable pull-off adhesion testers.2 They are capable of applying a concentric load and counter load to a single surface so that coatings can be tested even though only one side is accessible. Measurements are limited by the strength of adhesion bonds between the loading fixture, coating system and the substrate or the cohesive strengths of the glue, coating layers, and substrate.1.3 This test method is suitable for both laboratory and field testing.1.4 Pull-off strength measurements depend upon both material and instrumental parameters. There are different instruments used that comply with this test method. The specific instrument used should be identified when reporting results. This test is destructive and spot repairs may be necessary.1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.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.

5.1 This test method is intended for use on any type of finished leather.5.2 This test method will give an indication of the flexibility, adhesion, and strength of the finish on leather.1.1 This test method is intended for use on finished leather to evaluate resistance to cracking, delamination, and discoloration of the finish when subjected to repeated flexing. This test method does not apply to wet blue.1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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.

2.1 These tests are useful for production control and for acceptance testing of products.2.2 Interpreting the results of qualitative methods for determining the adhesion of metallic coatings is often a controversial subject. If more than one test is used, failure to pass any one test is considered unsatisfactory. In many instances, the end use of the coated article or its method of fabrication will suggest the technique that best represents functional requirements. For example, an article that is to be subsequently formed would suggest a draw or a bend test; an article that is to be soldered or otherwise exposed to heat would suggest a heat-quench test. If a part requires baking or heat treating after plating, adhesion tests should be carried out after such posttreatment as well.2.3 Several of the tests are limited to specific types of coatings, thickness ranges, ductility, or compositions of the substrate. These limitations are noted generally in the test descriptions and are summarized in Table 1 for certain metallic coatings.(A) + Appropriate; − not appropriate.2.4 “Perfect” adhesion exists if the bonding between the coating and the substrate is greater than the cohesive strength of either. Such adhesion is usually obtained if good electroplating practices are followed.2.5 For many purposes, the adhesion test has the objective of detecting any adhesion less than “perfect.” For such a test, one uses any means available to attempt to separate the coating from the substrate. This may be prying, hammering, bending, beating, heating, sawing, grinding, pulling, scribing, chiseling, or a combination of such treatments. If the coating peels, flakes, or lifts from the substrate, the adhesion is less than perfect.2.6 If evaluation of adhesion is required, it may be desirable to use one or more of the following tests. These tests have varying degrees of severity; and one might serve to distinguish between satisfactory and unsatisfactory adhesion in a specific application. The choice for each situation must be determined.2.7 When this guideline is used for acceptance inspection, the method or methods to be used must be specified. Because the results of tests in cases of marginal adhesion are subject to interpretation, agreement shall be reached on what is acceptable.2.8 If the size and shape of the item to be tested precludes use of the designated test, equivalent test panels may be appropriate. If permitted, test panels shall be of the same material and have the same surface finish as the item to be tested and shall be processed through the same preplating, electroplating, and postplating cycle as the parts they represent.1.1 This practice covers simple, qualitative tests for evaluating the adhesion of metallic coatings on various substances.1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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.

This test method establishes standard procedure for determining the tensile and tensile adhesion properties of rigid cellular plastics in the form of test specimens of standard shape under defined conditions of temperature, humidity, and testing machine speed. Tensile properties shall be measured using any of three types of specimens: Type A shall be the preferred specimen in those cases where enough sample material exists to form the necessary specimen; Type B shall be the preferred specimen when only smaller specimens are available, as in sandwich panels, etc.; Type C shall be the preferred specimen for the determination of tensile adhesive properties of a cellular plastic to a substrate as in a sandwich panel or the bonding strength of a cellular plastic to a single substrate. This test method requires the use of the following apparatuses: a constant-rate-of-crosshead-movement type testing machine; self-aligning type grips for holding test specimens; an extension indicator; and a lathe specimen cutter.1.1 This test method covers the determination of the tensile and tensile adhesion properties of rigid cellular materials in the form of test specimens of standard shape under defined conditions of temperature, humidity, and testing machine speed.1.2 Tensile properties shall be measured using any of three types of specimens:1.2.1 Type A shall be the preferred specimen in those cases where enough sample material exists to form the necessary specimen.1.2.2 Type B shall be the preferred specimen when only smaller specimens are available, as in sandwich panels, etc.1.2.3 Type C shall be the preferred specimen for the determination of tensile adhesive properties of a cellular plastic to a substrate as in a sandwich panel (top and bottom substrate) or the bonding strength of a cellular plastic to a single substrate.1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.NOTE 1: There is no known ISO equivalent to this test method.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.
