The data using this test method is useful for manufacturing control, specifications, research and development, and service evaluation. Need more than one copy?
atsm Have a question about conducting the test for this standard? Subscription pricing is determined by: Care needs to be taken to ensure good alignment during specimen preparation i. Large, indefinable, stress concentrations at the periphery of the adhesive layer can be expected to render the strength data meaningless.

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. This standard is also available to be included in Standards Subscriptions.
Rounding the adherend butt edges to a diameter equal to the adhesive thickness can facilitate their removal. This standard is not included in any packages. The average strength is taken as the applied load at failure divided by the bond area. Tensile strength data may be suitable for specification acceptance, service evaluation, manufacturing control, research, and development.
A small misalignment can severely reduce strength data.
The stress state at the overlap edges i. By means of our v2095 testing expertise and modular product design, we will help find the testing solution that is right for you. 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.
Your Alert Profile lists the documents that will be monitored. 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.
ASTM D determines the relative tensile strength of adhesives by the use of bar- and rod-shaped butt-joined specimens. Circular cross-section specimens are usually used to facilitate manufacture and maintain symmetry. Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM D Specimens may be designed with either a circular or square cross-section.

This test method is applicable to the testing of adhesives with various adherend materials in either similar or dissimilar combinations. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
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 d20955 required. In the absence of this restraint, the adhesive is free to undergo radial contraction x2095 respect to the stiffer adherend.
An alternative test method for determining the tensile strength of adhesives is Test Method D This test method is applicable to the testing of adhesives with various adherend materials in either similar or dissimilar combinations.
