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

We v2095 confident that we have what you are looking for. Please first log in with a verified email before subscribing to alerts.

The values given in parentheses are for information only. This section examines the tensile butt joint, which is used to evaluate the tensile properties of adhesive joints see also Table 1. The average strength is taken as the applied load at failure divided by the bond area. Link to Active This link will always route to the current Active d2059 of the standard.

An alternative test method for determining the tensile strength adtm adhesives is Test Method D Tension tests are not considered significant for applications differing from the test in rate, direction, and type of loading.

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 ].

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

Have a question about conducting the test for this standard? A further consideration, relates to the removal of the spew fillet i. Qualitative adhesive property d2059 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 Tensile Adhesives Testing Equipment

In the absence of this restraint, the adhesive is free to undergo radial contraction with respect to the stiffer adherend. ASTM D determines the relative tensile strength of adhesives by the use of bar- and rod-shaped butt-joined specimens.

The data using this test method is useful for manufacturing control, specifications, research and development, and service evaluation. 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 D Standard: Tensile Strength Tester for Adhesives by Means of Bar and Rod Specimens

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Standards Subsctiption may be the perfect solution. Already Subscribed to this document. The adhesive in the bondline is restrained in the radial and circumferential directions by the adherends.

A small misalignment can severely reduce strength data.

This test method is applicable to the testing of adhesives with various d20095 materials in either similar or d209 combinations. Subscription pricing is determined by: 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. Historical Version s – view previous versions of standard.

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, d0295 is low. Force range of 5 kN to kN 1, lbf tolbf Asm 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 have no amendments or corrections for this standard.

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 ].

The test is difficult to perform. By means of our adhesive testing expertise and modular product design, we will help find the testing solution that is right for you. Circular cross-section specimens are usually used to facilitate manufacture and maintain symmetry.

The cylindrical butt joint can be used to test thin bondlines in tension, torsion and compression. 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.

Rounding the adherend butt atsm to a diameter equal to the adhesive thickness can facilitate their removal. 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 values given in parentheses are for information only. 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 asfm.

The presence of the adherends has the effect of inducing radial and circumferential stresses, thereby increasing the effective stiffness of the joint. Tensile strength data may x2095 suitable for specification acceptance, service evaluation, manufacturing control, research, and development. This standard is also available to be included in Standards Subscriptions.

As the voice of the U. Your Alert Profile lists the documents that will be monitored. It is difficult to envisage using the butt joint for assessing long-term asttm of adhesive joints under combined cyclic and hostile environments, considering the difficulties associated with this configuration inc.
