ASTM D4501 – Standard Test Method for Shear Strength of Adhesive Bonds Between Rigid Substrates by the Block- Shear Method

ASTM D4501 – Block-Shear Strength Test

ASTM D4501 – This test method describes a procedure and fixture used to determine shear strengths of adhesives used to bond materials with moduli higher than

the modulus of the adhesive.

The size and shape of the specimens are variable within the physical restraints of the fixture.

Significance and Use

This test method provides an estimate of the shear strength of an adhesive on various machinable and nonmachinable substrate materials.

It is particularly applicable for testing bonds between ceramic, glass

Geometry

Thin square blocks of material are bonded together by the adhesive that is to be tested.

The exact size measurements of the test samples depends on the type of material being used.

The block-shear fixture is designed to accomodate specimens in sizes from 30x30x13mm (HxWxT) to 80x80x13mm.

Typically, a 1 inch square shearing block is adhered to the center of a larger square holding block.

*** Before conducting ASTM D4501 , it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
