Описание (английский):

ISO 13445:2003 specifies a method for the determination of the shear strength of adhesives used to bond materials with elastic moduli higher than the elastic modulus of the adhesive. The method provides an estimate of the shear strength of an adhesive on various machinable and non-machinable substrate materials.

Overview

ISO 13445:2003 is an international standard developed by ISO that specifies a reliable method for determining the shear strength of adhesive bonds between rigid substrates using the block-shear method. This test method applies particularly to adhesives bonding materials with elastic moduli higher than that of the adhesive, including machinable and non-machinable substrates such as metals, ceramics, glass, plastics, and composites.

The block-shear method provides an essential quantitative measure of adhesive performance, which is critical for ensuring the durability and integrity of bonded joints in various industrial applications.

Key Topics

Scope and Application ISO 13445 covers adhesives bonding materials with elastic moduli greater than the adhesive itself. It accommodates a wide range of substrate materials, including ceramic parts, glass, magnet moldings, plastics, and metals, especially where machining adherends is difficult or impractical.

Test Principle The method involves bonding blocks, plates, or discs and measuring the maximum force required to shear the bonded assembly apart. The shear strength is then calculated as the maximum force divided by the bond area.

Specimen Preparation

Adherends: specified dimensions for metals, glass, and other materials to avoid deformation during testing.
Surface preparation per EN 13887 to ensure proper adhesion.
Adhesive application follows manufacturer recommendations, with strict control of adhesive layer thickness within 0.02 mm.

Test Equipment

Tensile testing machine with a minimum capacity of 45 kN in tension calibrated per ISO 7500-1 requirements.
Shearing fixture comprising a specimen-holding block and a shearing tool designed to accommodate standard specimen sizes.
Adapter plates available for smaller specimen sizes to ensure secure placement during testing.

Test Procedure

Specimens are conditioned in a standard atmosphere according to ISO 291.
The specimen is loaded into the shearing fixture and tested at a crosshead speed of 1.5 mm/min.
The maximum force sustained by the adhesive bond is recorded, and the failure pattern classified according to ISO 10365.

Results and Reporting

Calculate maximum shear stress in megapascals by dividing maximum force by bond area.
Average results from a minimum of five specimens to determine shear strength.
Detailed reporting includes adhesive identification, adherend details, bonding conditions, adhesive layer thickness, test temperature, individual and average shear stress values, and failure mode.

Precision The current edition lacks interlaboratory precision data; future revisions will include this as data become available.

Applications

Quality Control in Manufacturing ISO 13445 testing ensures adhesives used in bonding rigid substrates meet necessary strength requirements for products such as electronics, automotive components, aerospace parts, and structural assemblies.

Material Research and Development Researchers use this standard to evaluate new adhesive formulations and bonding procedures, optimizing shear strength for advanced materials including ceramics and composites.

Failure Analysis Engineering teams apply the block-shear test method to investigate adhesive bond failures and improve joint designs or surface preparation methods.

Certification and Compliance Compliance with ISO 13445 supports adherence to international quality standards and facilitates global trade by providing a universally accepted test method for adhesive shear strength.
