4.1 If a coating is to fulfill its function of protecting or imparting unique properties to the surface of a substrate, it must adhere to the substrate for the expected service life. Because surface preparation (or lack of it) has a drastic effect on adhesion of coatings, a test method for evaluating adhesion to different surface treatments or of different coatings to the same treatment is of considerable use to the industry.4.2 The limitations of all adhesion methods, and the specific limitation of this test method to lower levels of adhesion (see 1.3) should be recognized before using it. These test methods are mechanized adaptations of Test Methods D3359; therefore, the intra- and interlaboratory precision of these test methods are similar to Test Methods D3359 and to other widely-accepted tests for coated substrates, for example, Test Method D2370, but this is partly the result of it being insensitive to all but large differences in adhesion. The pass-fail scale of 0 to 5 for Method B1 and B2 was selected deliberately to avoid a false impression of being sensitive.1.1 These test methods describe procedures for assessing the adhesion of metallic and inorganic coatings and other thin films to metallic and nonmetallic substrates. Assessment is made by applying pressure-sensitive tape to a coated surface and then utilizing a mechanical device to remove the tape at a regulated, uniform rate and constant angle while simultaneously recording the removal force.1.2 Four methods are described. Methods A1 and A2 are intended primarily for use on parts. Methods B1 and B2 are intended primarily for use in laboratory evaluations. Methods B1 and B2 are not recommended for testing coatings and films on polymer substrates.1.3 These test methods may be used to establish whether the adhesion of a coating to a substrate is within a required range (between a quantified low and a quantified high level). Determination of actual adhesive forces requires more sophisticated methods of measurement. In multilayer systems adhesion failure may occur between intermediate coating layers so that the adhesion of the total coating system to the substrate may not necessarily be determined.1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.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.

4.1 Pressure-sensitive film tapes are supplied in roll form. For such a tape to be useful a strip of the tape must be easily dispensed or severed from the roll by means of a cutter found on most dispensers. This test method is a means of measuring the ease of this severing or dispensing of the tape.4.2 This test method provides information that can be used in material specifications for product design and quality assurance applications. It can be used in comparing different tape products on specific dispensing blades.4.3 This test method may be suited for office and stationery and tapes with acetate, cellophane, or light-duty plastic backings. Some tapes may be shown to be difficult to dispense under these conditions yet are readily dispensable with other dispensing systems.NOTE 1: Backings described in CID A-A-113 are typical backings.1.1 This test method covers the measurement of the force and elongation required to dispense pressure-sensitive film tape on a 1-in. core intended for office and stationery applications from a desk-top dispenser.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 are not exact equivalents; therefore, each system must be used independently of the other.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 practice defines a consistent procedure for collecting surface material using clear, transparent, single sided adhesive collection medium, typically tape (also known as tape lift).4.2 A tape lift sample collected according to this practice is intended to be used to assess the material present at one specific location on a surface for fungal content.4.3 A tape lift sample collected from a point of interest can be used for qualitative analysis or to quantify fungal material per sample or per unit area. Note that the recovery efficiency of material from the surface sampled is unknown and a likely source of uncertainty for quantitative analyses.4.4 A tape lift sample collected according to this practice can be analyzed by direct microscopy.4.5 This practice may help supplement consistency in mold sampling during an indoor air quality investigation.1.1 This practice describes the protocols for collection of surface samples using tape lifts and their delivery to the laboratory.1.2 The purpose of this practice is to support the field investigator in differentiating fungal materials from non-fungal material such as scuffs, soot deposits, stains, pigments, dust, efflorescence, adhesives, and water stains.1.3 The samples collected by this practice are appropriate for either qualitative or quantitative analysis by direct microscopy.1.4 This practice does not address building occupant exposures, or occupant health risks.1.5 This practice does not address the development of a formal hypothesis or the establishment of sampling objectives.1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.7 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.1.8 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 significance of this test method is to standardize the analysis of the detection of removable fungal structures lifted from a surface with tape to improve consistency between laboratories and analysts.5.2 This test method is intended to ensure consistent data to the end user.5.3 Fungal structures are identified and semi-quantified regardless of whether they would or would not grow in culture.5.4 It must be emphasized that the detector in this test method is the analyst, and therefore results are subjective, depending on the experience, training, qualification, optical acuity, and mental fatigue of the analyst.5.5 This test method can be used to assess the presence and characteristics of fungal material on a surface.1.1 This test method uses optical microscopy for the detection, semi-quantification, and identification of fungal structures in tape lift preparations.1.2 This test method describes the preparation techniques for tape-lift matrices, the procedure for confirming the presence of fungal structures, and the reporting of observed fungal structures1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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.

3.1 The tape lift provides a rapid and simple technique for removing particles from a surface and determining their number and size distribution.3.2 By using statistically determined sample size and locations, an estimate of the surface cleanliness level of large areas can be made. The user shall define the sampling plan.3.3 The sampling plan shall consider the importance of surface geometry and surface orientation to gas flow, gravity, obstructions, and previous history of hardware. These factors influence particle fallout and entrapment of particles on the surface. The geometry of joints, recessed areas, fasteners, and the correspondence of particle-count data to area can be maintained.3.4 The selection of tape and the verification of its effect on the cleanliness of the hardware is very important. The tape adhesive should have sufficient cohesion to avoid transfer of the adhesive to the surface under test. The impact of adhesive transfer should be evaluated by laboratory testing before using the tape on the hardware. Since potential for adhesive transfer exists, cleaning to remove any adhesive might be required. In addition, the tape should have low outgassing characteristics, and as a minimum, it should meet the requirements of less than 1.0 % total mass loss (TML) and 0.1 % collected volatile condensable materials (CVCM), as measured by Test Method E595.3.5 Care should be exercised in deciding which surfaces should be tested by this practice. The tape can remove marginally adhering paint and coatings. Optical surfaces should not be tested until verification has been made that the surface coating will not be damaged. The minimum effectiveness of particle removal from smooth surfaces and angles down to 90° for all practice methods is 90 % for particles larger than 5 μm. Rough surface finishes result in low removal efficiencies. Surface finishes up to approximately 3.20 μm (125 μin.) have been tested and found to give satisfactory results.3.6 This practice has been tested only on surfaces at room temperature. Evaluation of temperature effects must be conducted prior to using the test on surfaces other than room temperature.3.7 Only personnel experienced in microscopic particle-counting techniques should be used to count and size the particles.1.1 This practice covers procedures for sampling surfaces to determine the presence of particulate contamination, 5 μm and larger. The practice consists of the application of a pressure-sensitive tape to the surface followed by the removal of particulate contamination with the removal of the tape. The tape with the adhering particles is then mounted on counting slides. Counting and measuring of particles is done by standard techniques.1.2 This practice describes the materials and equipment required to perform sampling of surfaces for particle counting and sizing.1.3 The criteria for acceptance or rejection of a part for conformance to surface cleanliness level requirements shall be determined by the user and are not included in this practice.1.4 This practice is for use on surfaces that are not damaged by the application of adhesive tape. The use of this practice on any surface of any material not previously tested, or for which the susceptibility to damage is unknown, is not recommended. In general, metals, metal plating, and oxide coatings will not be damaged. Application to painted, vapor deposited, and optical coatings should be evaluated before implementing this test.1.5 This practice provides three methods to evaluate tape lift tests, as follows:Practice Sections   A—This method uses light transmitted through the tape and tape adhesive to detect particles that adhere to it. 4 to 6 B—This method uses light transmitted through the tape adhesive after bonding to a base microscope slide, dissolving the tape backing, and a cover slide. The particles are embedded in the adhesive, and air bubbles are eliminated with acrylic mounting media. 7 to 9 C—This method uses light reflected off the tape adhesive to detect particles that adhere to it. 10 to 121.6 Units—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.1.7 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.1.8 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 guide is designed to assist an examiner in the selection of appropriate sample preparation methods for the analysis, comparison, and identification of pressure sensitive adhesive (PSA) tapes. If no meaningful differences are noted between the known and unknown samples regarding physical appearance or measurements, then IR spectroscopy should be the next step in the analytical scheme.5.2 Infrared spectroscopy can provide molecular information regarding major organic and inorganic components. For various reasons, components in lesser amounts are typically more difficult to identify unequivocally. Reasons for this include interference of the absorption bands of the major components with the less intense bands of minor components and sensitivity issues whereby the minor components are present at concentrations below the detection limits of the instrument.5.3 Infrared spectroscopy can be used to obtain spectra for elucidation of the chemical composition of a tape and for comparison of two or more tape samples. When used for spectral comparisons, the objective is to determine whether any meaningful differences exist between the samples.1.1 Infrared spectroscopy (IR) is a valuable method for the identification and comparison of pressure sensitive tapes (1-20).2 This guide provides basic recommendations and information about infrared spectrometers and accessories, with an emphasis on sampling techniques specific to pressure sensitive tape examinations. The particular method(s) employed by each examiner or laboratory will depend upon available equipment, examiner training, sample suitability, and sample size.1.2 This guide is intended for examiners with a basic knowledge of the theory and proficiency in the use of infrared spectroscopy as well as experience in the handling and forensic examination of pressure sensitive tapes. Further, this guide is to be used in conjunction with a broader analytical scheme (21-23).1.3 Disclaimer: This guide offers a set of instructions for performing one or more specific operations. This standard cannot replace knowledge, skill, or the ability acquired through appropriate education, training, and experience and should be used in conjunction with sound professional judgment.1.4 The values stated in SI units are to be regarded as standard.
