ASTM D1002 Apparent Shear Strength of Single-Lap Joint Adhesively Bonded Metal Specimens
ASTM D1002 is a test method that determines the shear strength of single-lap joint adhesively bonded metal specimens by tension loading under specified conditions of preparation and test. Read more about ASTM D1002 Apparent Shear Strength of Single-Lap Joint Adhesively Bonded Metal Specimens below.

Introduction to ASTM D1002
ASTM D1002 is a test method designed to measure the shear strength of adhesives for bonding metals when tested on a single lap-joint specimen. Adhesive strength, surface preparation parameters, and adhesive environmental durability are determined by this test method. The results obtained are specially used for quality control and specification purposes.
ASTM D1002 test method is generally applicable for specifying lap shear for metal to metal. The test method has found applications in controlling surface preparations, primer, and adhesive systems for determining the strength properties of tested systems.
ASTM D1002 Test Method
Adhesive is used to join two metal plates, which are then properly cured. The assembly is then divided into specimens with uniform lap shear widths. A universal testing device is used to pull the test specimens at a rate of 1.3 mm per minute (0.05 in per minute) until a rupture occurs. The grips that hold the assembly’s ends in place, line up for the applied force to pass through the specimen’s centerline. Cohesive (the adhesive ruptures within itself) or adhesive failures (when the glue separates from one of the substrates) are two possible types of failure.
Cohesive Failure
The specimen is placed in the grips of the testing machine and the loading is applied at the rate of shear area per min. The loading is continued till failure at a free crosshead speed of 1.3 m. If the adhesive ruptures within itself then it leads to cohesive failure.
Adhesive Failure
The load at failure is recorded and the nature and amount of failure are determined. If the glue separates from one of the substances then it leads to adhesive failure.
ASTM D1002 Specimens
Specimen details
ASTM D1002 Specimens can be brass, copper, aluminum, steel, titanium, and corrosion-resisting steel.
Specimen dimensions
The lap shear specimen is 25.4 mm (1′′) wide, with an overlap of 12.7 mm (0.5′′). The recommended metal thickness is 1.62 mm (0.064′′) and the overall length of the bonded specimen is taken as 177.8 mm (7′′).
Specimen preparation
Specimens are cut from the panel and the panel area is trimmed for final preparation.
ASTM D1002 Results
This test method evaluates load at failure (N or Ibf) and shear strength at failure (MPA or PSI). The nature and amount of failure are also determined. The failing loads are expressed in kilograms per square centimeter of shear area.
Tests related to ASTM D1002 ISO 22841 is similar to ASTM D1002. As per the ASTM D1002 test method, we determine the tensile lap shear strength for metal to metal whereas, in the case of ISO 22841, we determine the lap shear strength of the adhesive joint between carbon fiber-reinforced plastics and metal adherends. It uses standard specimens loaded in tension under specified conditions of preparation, conditioning, and testing.
