| Summary | This standard specifies the required conditions using standard samples evaluated by loading shear stress fatigue strength adhesive tensile shear test methods. Aim was to characterize structural adhesives in the performance of a specific metal substrates. Fatigue performance is a function of the specimen geometry. Test results and the intrinsic properties of the adhesive independent, and can not be used for design purposes. |

Part Normative references replaced by the national standards with international standards, there is no difference in content standards with international standards referenced.
For ease of use, this standard to the following editorial changes.
a) "this International Standard" be replaced by "this standard";
b) The standard normative references using "ISO 17212.2004" instead of the original international standard adopted "ISO 4588.1995";
c) Remove the preface to the international standards.
The standard proposed by China Petroleum and Chemical Industry Association.
This standard by the National Standardization Technical Committee adhesive (SAC/TC185) centralized.

Structural Adhesives Adhesive tensile shear fatigue
Standard Test Method for Performance
1 Scope
This standard specifies the required conditions using standard samples by loading the shear stress evaluation of adhesive tensile shear fatigue test
Test methods. Aim is to characterize the structural adhesive performance on a particular metal substrate.
Fatigue performance is a function of sample geometric distribution. It has nothing to do with the inherent characteristics of the test results of the adhesive, and can not be used for design purposes.
2 Normative references
The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent
Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research
Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard.

3 Terms and definitions, symbols
This standard uses the following terms and symbols.
3.1
Shear stress shearstress (τ)
The external force divided by the bonding area, the unit is MPa.
3.2
Static shear stress staticshearstrength (τR)
According to GB/T 7124 is determined as the average static shear strength at failure, the unit is MPa.
3.3
Stress cycle stresscycle
Regular intervals with repeated stress/time function of the smallest unit.
