We are confident that we have what you are looking for. Force range of 5 kN to astn 1, lbf tolbf Adjustable test space The most popular choice for static tension f2095 compression tests These dual column testers are available in both tabletop and floor standing models. This standard is not included in any packages.
Subscription pricing is determined by: 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. Add to Alert PDF. The qstm state at the overlap edges i. Significant bending can be induced due to misalignment of the adherends, resulting in premature failure.
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. Proceed to Checkout Continue Shopping. Circular cross-section specimens are usually used to facilitate manufacture and maintain symmetry.
The average strength is taken as the applied load at failure divided by the bond area. ASTM D determines the relative tensile strength of adhesives by the use of bar- and rod-shaped butt-joined specimens.
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.
Standards Subsctiption may be the perfect solution. A further consideration, relates to the removal of the spew fillet i. This section examines the tensile butt joint, which is used to evaluate the tensile properties of adhesive joints see also Table 1.
An alternative test aetm for determining the tensile strength of adhesives is Test Method D Tensile stresses are virtually impossible to avoid, however there is a need for reliable test methods to measure the tensile properties of the adhesive.

ASTM D Standard: Tensile Strength Tester for Adhesives by Means of Bar and Rod Specimens
The adhesive in the bondline is restrained in the radial and circumferential directions by the adherends. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

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. Your Alert Profile lists the documents that will be monitored. We have no amendments or corrections for this standard.
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. As the voice of the U. This test method is applicable to the testing of adhesives with various adherend materials in either similar or dissimilar combinations. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.
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.
Both circular and square cross-sections, 10 to 50 mm wide, are included within BS EN 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 ].
ASTM D2095 Glass Pillar Test
Historical Version s – view previous versions of standard. Specimens may be designed with either a circular or square cross-section.
The test is difficult to perform. In the absence of this restraint, the adhesive is free to undergo radial contraction with respect to the stiffer adherend. The tensile stresses in the central region of the adhesive layer for butt d0295 specimens are uniformly distributed and there are no shear stresses present [ 6—7 ]. You may delete a document from your Alert Profile at any time. Transfer of load to an adhesively bonded structure by tension, either directly or indirectly peelrepresents the most c2095 form of loading, since the strength of the joint relies on the tensile strength of the adhesive, which is low.
The cylindrical butt joint can be used to test thin bondlines in tension, torsion and compression. 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 astj. A small misalignment can severely reduce strength data. By r2095 of our adhesive testing expertise and modular product design, we will help find the testing solution that is right for you.

Large, indefinable, stress concentrations at the periphery of the adhesive layer can be expected to render the strength data meaningless. Please first astn in with a verified email before subscribing to alerts. Rounding the adherend butt edges to a diameter equal to the adhesive thickness can facilitate their removal.

This standard is also available to be included in Standards Subscriptions. 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.
The reader should refer to the ISO standards relating to the testing of polymeric materials [ 12 ].
