Circular cross-section specimens are usually used to facilitate manufacture and maintain symmetry. In marked contrast, the stress state in the outer edges is highly complex, varying through the thickness of the adhesive layer.
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.
Tensile strength data may be suitable for specification d0295, service evaluation, manufacturing control, research, and development. Tensile stresses are virtually impossible to avoid, however there is a need for reliable test methods to measure the tensile properties of the adhesive.
The test is difficult to perform. Already Subscribed to this document. This analysis assumes d209 the adhesive has a much lower stiffness than the adherends i. This standard is not included in any packages.
This standard is also available to be included in Standards Subscriptions. An alternative test method for determining the tensile strength of adhesives is Test Method D The spew is able to transmit some of the applied load, resulting in a significant reduction in the level of axial stresses within the adhesive joint, and thus contributing to the uncertainty in moduli and strength data.
Large, indefinable, stress concentrations at the periphery of the adhesive layer can be expected to render the strength data meaningless. The adhesive in the bondline is restrained in the radial and circumferential directions by the adherends. Significant bending can be induced due to misalignment of the adherends, resulting in premature failure. The data using this test method xstm useful for manufacturing control, specifications, research and development, and service evaluation.
The tensile stresses in the central region of the adhesive layer for butt tension specimens are uniformly distributed and there are no shear stresses present [ 6—7 ]. It is difficult to envisage using the butt joint for assessing long-term performance of adhesive joints under combined cyclic and hostile environments, considering the difficulties associated with this configuration inc.
Specimens may be designed with either a circular or square cross-section.
wstm Need more than one copy? This test method is applicable to the testing of adhesives with various adherend materials in either similar or dissimilar combinations.

Your Alert Profile lists the documents that will be monitored. The reader should refer to the ISO standards relating to the testing of polymeric materials [ 12 ].
Subscription pricing is determined by: This test method is applicable to the testing of adhesives with various adherend materials in either similar or dissimilar combinations. Rounding the adherend butt edges to a diameter equal to the adhesive thickness can facilitate their removal.
ASTM D2095 – 96(2015)
Tension tests are not considered significant for applications differing from the test in rate, direction, and type of loading. A further consideration, relates to the removal of the spew fillet aastm. Qualitative adhesive property d22095 only Strain measurements satm High shear and peel stresses at bondline edges Strength sensitive to spew fillet Sensitive to specimen misalignment Limited to thick and rigid adherends Failure attributed to peel stresses Special bonding fixture required.
The values given in parentheses are for information only. Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column testers are available in both tabletop and floor standing models. Give one of our application engineers a call satm for help with creating the best budget and testing plan according to ASTM D The stress state at the overlap edges i. By means of our adhesive testing expertise and modular product design, we will help find the testing solution that is right for you.
You can download and open this file to your own computer but DRM prevents opening this file on another satm, including a networked server. Forces up to 10 kN 2, lbf Low force tabletop systems Modular series of five frame options with adjustable test space Affordable testing option for tension, compression, bend, peel and much more. In the absence of this restraint, the adhesive is free to undergo radial contraction with respect to the stiffer adherend.
The values given in parentheses are for information only. We are confident that we have what you are looking for. It is good design practice, therefore, to ensure that the load is transferred by shear or compression and that direct or induced tensile stresses are minimised.
Care needs to be taken to ensure good alignment during specimen preparation i. This test method is applicable to the testing of adhesives with various adhered materials in either similar or dissimilar combinations.
