4.1 This test method is specifically designed to measure the performance of adhesives in finger joints manufactured under production line conditions.4.1.1 The test method can be adapted to evaluate the adhesive performance of laboratory produced finger joints using commercial finger joint cutting heads with finger joints produced following the adhesive manufacturers recommendations. The conditions under which the finger joints were produced, including any limitations, are to be reported in 9.1.2.2 (see Note 2).NOTE 2: If laboratory prepared finger joints are to be produced, record details related to adhesive used, its preparation, application to the cut finger joint, appropriate bonding parameters and limitations in the production of the finger joint assemblies.4.2 The results of the test method may be used to certify an adhesive as suitable for finger jointing lumber under production line conditions where the intended end use of the finger jointed lumber may be in a variety of bonded structural wood products.4.2.1 When the test results are to be used for certification of an adhesive a standard wood species shall be used.4.2.1.1 Standard species may be found in Table 1 of Specification D2559.1.1 This test method is designed to evaluate adhesives for finger jointing lumber used in the manufacture of a variety of bonded structural wood products such as structural glued laminated timber. It tests the tensile strength of joints under the following treatments: dry with no treatment, wet after one vacuum-pressure soak treatment, and wet after cyclic boil-dry treatment.1.2 This test method is intended neither for quality control as the test assemblies are selected for the absence of defects usually found in run-of-the-mill finger joints nor as a substitute for in-plant qualification of end joints, including full-scale joint tests.NOTE 1: This test method is specifically designed to evaluate adhesives for use in finger jointing lumber using small scale test specimens cut from carefully selected finger joint assemblies. In contrast, plant qualification and quality control require tests of full scale end joints selected randomly from production, designed to evaluate parameters beyond adhesive performance which affect the performance of the end use product.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 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.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 applied in the case in which there is no test item in the vacuum chamber (such as during bake-out operations), this procedure may be used to evaluate the performance of the vacuum chamber in relation to other data from the same or other chambers given that critical parameters (for example, length of exposure, temperature of the chamber and cold finger, anisotropy, and so forth) can be related.5.2 The procedure can be used to evaluate the effects of materials found in the residue on items placed in the vacuum chamber.5.3 The procedure can be used to describe the effect of a prior test on the residual gases within a vacuum chamber.5.4 By selecting the time at which the coolant is introduced into the cold finger, the environment present during a selected portion of a test can be characterized. This can be used to determine the relative efficacy of certain vacuum chamber procedures such as bake-out.5.5 The procedure may be used to define the outgassed products of a test item that condense on the cold finger.5.6 The procedure may be used in defining the relative cleanliness of a vacuum chamber.5.7 In applying the results of the procedure to the vacuum chamber in general, consideration must be given to the anisotropy of the molecular fluxes within the chamber.5.8 The procedure is sensitive to both the partial pressures of the gases that form the condensibles and the time of exposure of the cold finger at coolant temperatures.5.9 The procedure is sensitive to any losses of sample that may occur during the various transfer operations and during that procedure wherein the solvent is evaporated by heating it on a steam bath.NOTE 1: Reactions between solvent and condensate can occur and would affect the analysis.1.1 This practice covers a technique for collecting samples of materials that are part of the residual gas environment of an evacuated vacuum chamber. The practice uses a device designated as a “cold finger” that is placed within the environment to be sampled and is cooled so that constituents of the environment are retained on the cold-finger surface.1.2 The practice covers a method for obtaining a sample from the cold finger and determining the weight of the material removed from the cold finger.1.3 The practice contains recommendations as to ways in which the sample may be analyzed to identify the constituents that comprise the sample.1.4 By determining the species that constitute the sample, the practice may be used to assist in defining the source of the constituents and whether the sample is generally representative of samples similarly obtained from the vacuum chamber itself.1.5 This practice covers alternative approaches and usages to which the practice can be put.1.6 The degree of molecular flux anisotropy significantly affects the assurance with which one can attribute characteristics determined by this procedure to the vacuum chamber environment in general.1.7 The temperature of the cold finger significantly affects the quantity and species of materials collected.1.8 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.9 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. For specific warning statements, see Section 8.1.10 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 Adhesives are classified as dry use or wet use. Each classification includes consideration of short-term in-transit exposure conditions at elevated temperatures up to 220°F (104°C).5.2 The initial development of Specification D3110 was based on finger-joint assemblies made under controlled laboratory conditions. In the development of this revised specification the results obtained with laboratory-made specimens (see 12.1.2) were compared to those obtained with industrially manufactured specimens (see 12.1.1). These finger joints were prepared using previously certified adhesives in cooperation with a manufacturer or equipment supplier who had the necessary finger-joint cutter and assembly equipment. These finger joints may vary in geometry and length from manufacturer to manufacturer, and this variation could affect the performance of the bonded-finger-joint assembly.5 (See 12.1, 12.4, and 12.5.) Fig. 3 depicts a sample finger-joint configuration.5.2.1 When changes are made in the design of the industrially manufactured finger joint, the new design should be compared to a control design that has been used successfully.5.3 An industrially manufactured finger joint should be evaluated using the requirements for compliance with this specification, in accordance with 4.1. When this specification is used to evaluate specimens made from field-manufactured assemblies, the results may not compare favorably with those run on specimens made from laboratory-made assemblies.5.4 Test requirements are provided to determine if the adhesive is suitable for dry use or wet use.5.5 The dry test and exposure conditions and treatments are to evaluate adhesives used in nonstructural finger joints for typical service conditions.5.5.1 The 220°F (104°C) test, a more severe test, is designed to evaluate the product after exposure to short-term elevated-temperature conditions. This test is intended to simulate conditions that might be experienced in transit, further processing, or in-service conditions.NOTE 4: These typical service conditions could include stress and time under stress, as well as elevated temperature.5.6 Procedures are described in sufficient detail to permit duplication in different testing laboratories.5.6.1 Record any deviations in these procedures on the report forms, Appendix X1, as it may have an impact on the results obtained. Test data are only valid for the length and design used. (See 12.4.)5.7 To avoid potential problems that would be caused by interrupting the bonding process, the adhesive-performance level should be determined by the finger-joint manufacturer prior to handling and early shipment. Before beginning the full testing process, the testing laboratory should pull a representative sample and check the dry strength first, in order to ensure that the product basically conforms with the performance level certified by the adhesive manufacturer.AbstractThis specification establishes the performance levels for adhesives to be used in finger joints in nonstructural bonded-lumber products. Such products include, but are not limited to, interior and exterior mouldings, window and door components or parts, and bonded-lumber panels. The apparatus shall consist of environmental chamber for moist-heat aging, oven with sufficient air circulation to remove moisture from the chamber, tanks for soaking and boiling, testing machines for the flexure and tension specimens, and vacuum-pressure vessel. Tests shall be conducted such as dry, soak, elevated-temperature, and temperature-humidity tests for dry-use classification and dry, boil, elevated-temperature, and vacuum-pressure tests for the wet-use classification. The adhesives shall be tested for performance which shall meet the following requirements: moisture content; specific gravities of wood species; tensile strength; wood failure for soft and hard woods; and rupture modulus.1.1 This specification establishes performance levels for adhesives to be used in finger joints in nonstructural bonded-lumber products. Such products include, but are not limited to, interior and exterior mouldings, window and door components or parts, and bonded-lumber panels. Adhesives that meet the requirements of the various performance classes are considered capable of providing an adequate bond for use under the conditions described for the class. This specification is to be used to evaluate adhesives as well as the adhesive bonds in the finger joints. See Section 5, , for limitations when using this specification to evaluate industrially manufactured finger joints.NOTE 1: This specification supersedes the finger-joint portion of the 1990 edition of Specification D3110.1.2 The following index is provided as a guide to the test methods in this specification:  SectionApparatus  6Equipment, Material, and Preparation of Assemblies and Specimens  7Conditioning for Factory-Manufactured Assemblies, Laboratory-Made Assemblies, and Test Specimens  8Testing in Flexure  9Testing in Tension 10Exposure Conditions and Treatments 11  1. Dry Use Tests: Dry, 3-cycle Soak, Elevated Temperature, and Temperature-Humidity  11.1  2. Wet Use Tests: Dry, Boil, Elevated Temperature, and Vacuum-Pressure  11.2NOTE 2: The conditioning needed for various stages in the preparation of both types of specimens and for the exposure tests are given.NOTE 3: Specific guidelines for specimen size, exposure conditions, testing, calculation, and reporting are given for flexure specimens in Sections 9 and 11, and for tension specimens in Sections 10 and 11.1.3 For the definitions of dry use and wet use, see 3.2.1.1 and 3.2.1.2.1.4 The values stated in inch-pound units are to be regarded as standard. The SI units given in parentheses are for information only.1.5 The following precautionary caveat pertains only to the apparatus and test methods portions, Sections 6 – 11 of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use.
