Care needs to be taken to ensure good alignment during specimen preparation i. Please first verify your email before subscribing to alerts.
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.
Significant bending can be induced due to misalignment of the adherends, resulting in premature failure. Proceed to Checkout Continue Shopping. The values given in parentheses are for information only. The cylindrical butt joint can be used to test thin bondlines in tension, torsion and compression. You may delete a document from your Alert Profile at any time. The test is difficult to perform.
The stress state at the overlap edges i. 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 ]. 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 values given in parentheses are for information only. We are confident that we have what you are looking for. Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM D The data using this test method is useful for manufacturing control, specifications, research and development, and service evaluation.
Your Alert Profile lists the documents that will be monitored.
ASTM D2095 Glass Pillar Test
The adhesive in the bondline is restrained in the radial and circumferential directions by the adherends. The reader should refer to the ISO standards relating to the testing of polymeric materials [ 12 ].
Both circular and square cross-sections, 10 to 50 mm wide, are included within BS EN Tensile stresses are virtually impossible to d095, however there is a need for reliable test methods to measure the tensile properties of the adhesive.
A further consideration, relates to the removal of the spew fillet i. This test method is applicable to the testing of adhesives with various adhered materials in either similar or dissimilar combinations. This section examines the tensile butt joint, which is used to evaluate the tensile properties of adhesive joints see also Table 1.
If the document is revised or amended, you will be notified by email. 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.
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. Add to Alert PDF. Specimens may be designed with either a circular or square cross-section. Standards Subsctiption may be the perfect solution.
ASTM D Tensile Adhesives Testing Equipment
Circular cross-section specimens are usually used to facilitate manufacture and maintain symmetry. ASTM D determines the relative tensile strength of adhesives by the use of bar- and rod-shaped butt-joined specimens.
Link to Active This link will always route to the current Active version of the standard. As the voice of the U.
Need more than one copy? In marked contrast, the stress state in the outer edges is highly complex, varying through the thickness of the adhesive layer. Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These awtm column testers are available in both tabletop and floor standing models.
ASTM D Standard: Tensile Strength Tester for Adhesives by Means of Bar and Rod Specimens
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.
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. 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.
Rounding the adherend butt edges to a diameter equal to the adhesive thickness can facilitate their removal.
