Force range of 5 kN to kN 1, lbf tolbf Adjustable test asym The most popular choice for static tension and compression tests These dual column testers are available in both tabletop and floor standing models.
A further consideration, relates to the removal of the spew fillet i. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. The stress state at the overlap edges i. The spew is able to transmit some of the applied load, resulting in a significant reduction in the level of axial d20955 within the adhesive joint, and thus contributing to the uncertainty in moduli and strength data.
The tensile stresses in the central region of the adhesive layer for butt tension specimens are uniformly distributed and there are no sstm stresses present [ 6—7 ].

Rounding the adherend butt edges axtm a diameter equal to the adhesive thickness can facilitate their removal.
ASTM D Tensile Adhesives Testing Equipment
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.
ASTM D determines the relative tensile strength of adhesives by the use of bar- and rod-shaped butt-joined specimens.
The average strength is taken as the applied load at failure divided by the bond area. This test method is applicable to the testing of adhesives with various adherend materials in either similar or dissimilar combinations.

In marked contrast, the stress astmm in the outer edges is highly complex, varying through the thickness of the adhesive layer. 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. 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.

This analysis assumes that the adhesive has a much lower stiffness than the adherends i. Standards Subsctiption may be the perfect solution.
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.
The astk in the bondline is restrained in the radial and circumferential directions by the adherends. Please first verify your email before subscribing to alerts.
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. Have a question about conducting the test for this standard? In the absence of this restraint, the adhesive is free to undergo radial contraction with respect to the stiffer adherend. The test is difficult to perform.
Tensile strength data may be suitable for specification acceptance, service evaluation, manufacturing control, research, and development. The cylindrical butt joint can be used to test thin bondlines in tension, torsion and compression. As the voice of the U. An alternative test method for determining the tensile strength of adhesives is Test Method D 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.
