The average strength is taken as the applied load at failure divided by the bond area.

An alternative test method for determining the tensile strength of adhesives is Test Method D This standard is not included in any packages. As the voice of the U. 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 [ asm ].

ASTM D Standard: Tensile Strength Tester for Adhesives by Means of Bar and Rod Specimens

The values given in parentheses are for information only. In marked contrast, the stress state in the outer edges is highly complex, varying through the thickness of the adhesive layer. In the absence of this restraint, the adhesive is free to undergo radial contraction with respect to the stiffer adherend. This section examines the tensile butt joint, which is used to evaluate the tensile properties of adhesive joints see also Table 1.


Proceed to Checkout Continue Shopping. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Subscription pricing is determined by: 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 stress state at the overlap edges i. This test method is applicable to the testing of adhesives with various adherend materials in either similar or dissimilar combinations. This standard is also available to be included in Standards Subscriptions. 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. Already Subscribed to this document.

We have no amendments or corrections for this standard.

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. The presence of the adherends has the effect of inducing radial and circumferential stresses, thereby increasing the effective stiffness of the joint.

Tensile stresses are virtually impossible to avoid, however there is a need for reliable test methods to measure the tensile properties of the adhesive. Standards Subsctiption may be the perfect solution. The data using this test method is useful for manufacturing control, specifications, research and development, and service evaluation.

This test method is applicable to the testing of adhesives with various adherend materials in either similar or dissimilar combinations.


ASTM D2095 Glass Pillar Test

Tension tests are not considered significant for applications differing from the test in rate, direction, and type of loading. 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.

Both circular and square cross-sections, 10 to 50 mm wide, are included within BS EN Circular cross-section specimens are usually used to facilitate manufacture and maintain symmetry.

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 test is difficult to perform. Please first verify your email before subscribing to alerts. This analysis assumes that the adhesive has a much lower stiffness than the adherends i. Significant bending can be induced due to misalignment of the adherends, resulting in premature failure.

An alternative test method for determining the tensile strength of adhesives is Test Method D If the document is revised or amended, you will be notified by email.

The reader should refer to the ISO standards relating to the testing of polymeric materials [ 12 ].
