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. The adhesive in the bondline is restrained in the radial and circumferential directions by the adherends. Rounding the adherend butt edges to a diameter equal to the adhesive thickness can facilitate their removal.

This section examines the tensile butt joint, which is used to evaluate the tensile properties of adhesive joints see also Table 1. Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM D Your Alert D209 lists the documents that will be monitored.
This test method is applicable to the testing of adhesives with various adherend materials in either similar or dissimilar combinations. As the voice of the U. Referenced Documents c2095 separately The documents listed below are referenced within the subject standard but are not provided as part of d295 standard.
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 i. Significant bending can be induced due to misalignment of the adherends, resulting in premature failure.
Already Subscribed to this document. The values asym in parentheses are for information only. This standard is not included in any packages.
The tensile stresses in the central region of the adhesive layer for butt tension specimens are uniformly distributed and astmm are no shear stresses present [ 6—7 ]. This standard is also available to be qstm in Standards Subscriptions. By means of our adhesive testing expertise and modular product design, we will help find the testing solution that is right for you. ASTM D determines the relative tensile strength of adhesives by the use of bar- and rod-shaped butt-joined specimens.
Circular cross-section specimens are usually used to facilitate manufacture and maintain symmetry. Large, indefinable, stress concentrations at the periphery of the adhesive layer can be expected to render the strength data meaningless. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the zstm of regulatory limitations prior to use.

In marked contrast, the stress state in the outer edges is highly complex, varying through the thickness of the adhesive astj. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.
ASTM D2095 Tensile Adhesives Testing Equipment
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. This test method is applicable to the testing of adhesives with various adherend materials in either similar or dissimilar combinations.
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. Standards Subsctiption may be the perfect solution.
The cylindrical butt joint can be used to test thin bondlines in tension, torsion and compression. Test methods that can be used to measure the static, fatigue and creep behaviour of engineering adhesives, in bulk form, will not be covered in this section. We have no amendments or corrections for this standard. If the document is revised or amended, you will be notified by email. Both circular and square cross-sections, 10 to 50 mm wide, are included within BS EN A small misalignment can severely reduce strength data.
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. We are confident that we have what you are looking for. An alternative test method for determining the tensile strength of adhesives is Test Method D Qualitative adhesive property data only Strain measurements difficult 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.
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. The data using this test method is useful for manufacturing control, specifications, research and development, and service evaluation. The stress state at the overlap edges i. Care needs to be taken to ensure good alignment during specimen preparation i.
Tensile strength data may be suitable for specification acceptance, service evaluation, manufacturing control, research, and development. The values given in parentheses are for information only. 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 stresses are virtually impossible to avoid, however there is a need for reliable test methods to measure the tensile properties of the adhesive. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.
