Tensile stresses are virtually impossible to avoid, however there is a need for reliable test methods to measure the tensile properties of the adhesive. As the voice of the U. Transfer of load to an adhesively bonded structure by tension, either directly or indirectly peelrepresents the most severe form of loading, since the strength of the joint relies on the tensile strength of the adhesive, which is low.
The data using this test method is useful for manufacturing control, specifications, research and development, and service evaluation.

Subscription pricing is determined by: An alternative test method for determining the tensile strength of adhesives is Test Method D The presence of the adherends has the effect of inducing radial and circumferential stresses, thereby increasing the effective stiffness of the joint.

Qualitative adhesive property data only Strain measurements astj 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.
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.
This effectively increases the bondline thickness at the outer edges of the bondline, and as a result non-linear stress effects may result, especially at elevated temperatures and exposure to high humidity environments [ 6—7 ]. This test method is applicable to the testing of adhesives with various adhered materials in either similar or dissimilar combinations.
Significant bending can be induced due to misalignment of the adherends, resulting in premature failure. Already Subscribed to this document.
ASTM D Standard: Tensile Strength Tester for Adhesives by Means of Bar and Rod Specimens
A further consideration, relates to the removal of the spew fillet i. 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. A small misalignment can severely reduce strength data. 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 ].

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.
Large, indefinable, stress concentrations at the periphery of the adhesive layer can be expected to render the strength data meaningless. Standards Subsctiption may be the perfect solution.
In the absence of this restraint, the adhesive is free to undergo radial contraction with respect to the stiffer adherend. 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. 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.

The test is difficult to perform. Specimens may be designed with either a circular or square cross-section.
