Circular cross-section specimens axtm usually used to facilitate manufacture and maintain symmetry. Specimens may be designed with either a circular or square cross-section. The reader should refer to the ISO standards relating to the testing of polymeric materials [ 12 ]. Tensile stresses are virtually impossible to avoid, however there is a need for reliable test methods to measure the tensile properties of the adhesive.
The presence of the adherends has the effect of inducing radial and circumferential stresses, thereby increasing the effective stiffness of the joint. In the absence of this restraint, the adhesive is free to undergo radial contraction with respect to the stiffer adherend. Need more than one copy?

ASTM D2095 Tensile Adhesives Testing Equipment
The stress state at the overlap edges i. 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. Tensile strength data may be suitable for specification acceptance, service evaluation, manufacturing control, research, and development.
The average strength is taken as the applied load at failure divided by the bond area. Force range of d095 kN to kN 1, lbf to astj, lbf 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.
If the document is revised d209 amended, you will be notified by email. Rounding the adherend butt edges to a diameter equal to the adhesive thickness can facilitate their removal. Please first log in with a verified email before subscribing to alerts.
Care needs to be taken to ensure good alignment during specimen preparation i. 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.
Large, indefinable, stress concentrations at the periphery of the adhesive layer can be expected to render the strength data meaningless. Historical Version s – view previous versions of standard. By means of our adhesive testing expertise and modular product design, we will help find the testing solution that is right for you.
Both circular and square cross-sections, 10 to 50 mm wide, are included within BS EN This standard is also available to be included in Standards Subscriptions. Standards Subsctiption may be the perfect solution. Asm 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.
This section examines the tensile butt joint, which is used to evaluate the tensile properties of adhesive joints see also Table 1. The values given in parentheses are for information only. This analysis assumes that the adhesive has a much lower stiffness than the adherends i. This test method is applicable to the testing of adhesives with various adherend materials in either similar or dissimilar combinations.
