A further consideration, relates to the removal of the spew fillet i. An alternative test method for determining the tensile strength d20095 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.

R2095 stress state at the overlap edges i. ASTM D determines the relative tensile strength of adhesives asgm the use of bar- and rod-shaped butt-joined specimens. Your Alert Profile lists the documents that will be monitored. 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.

Circular cross-section specimens are usually used to facilitate manufacture and maintain symmetry. You can download and open this file to your adtm computer but DRM prevents opening this file on another computer, including a networked server. Standards Subsctiption may be the perfect solution. This test method is applicable to the testing of adhesives with various adhered materials in either similar or dissimilar combinations.

Already Subscribed to this document. The values given in parentheses are for information only. Rounding the adherend butt edges atm a diameter equal to the adhesive thickness can facilitate their removal. In marked contrast, the stress state in the outer edges is highly complex, varying through the thickness of the adhesive layer.

The test is difficult to perform. Historical Version s – view previous versions of 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 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.

This section examines the tensile butt joint, which is used to evaluate the tensile properties of adhesive joints see also Table 1.

We are confident that we have what you are looking for. 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 ].

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

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. This test method is applicable to the testing of adhesives with various adherend materials in either similar s2095 dissimilar d2059.

Large, indefinable, stress concentrations at the periphery of the adhesive layer can be expected to render the strength data meaningless.

Tension tests are not considered significant for applications differing from the test in rate, direction, and type of loading. This analysis assumes that the adhesive has a much lower stiffness than the adherends i. The adhesive in the bondline is restrained in the radial and circumferential directions by the adherends. Care needs to be taken to ensure good alignment during specimen preparation i. Specimens may be designed with either a circular or square cross-section.

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.

In the absence of this restraint, the adhesive is free to undergo radial contraction with respect to the stiffer adherend.

The reader should refer to the ISO standards relating to the testing of polymeric materials [ 12 ]. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

The average strength is d2059 as the applied load at failure divided by the bond area.

Tensile stresses are virtually impossible to avoid, however there is a need for reliable test methods to measure the tensile properties of the adhesive. It is good design practice, therefore, to ensure that the asfm is transferred by shear or compression and that direct or induced tensile stresses are minimised.
