Double Shear Test Specimens
Double Shear Test Specimens (Product Code: SLE/ETP/07) are copper test pieces used to measure a material's shear strength in double-shear tests in engineering and materials testing laboratories. Each specimen is 50 mm long with a diameter of 5.65 to 6 mm, and in the test it is cut across two planes at once, which gives a balanced loading arrangement for student practicals. They are supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as consumables for engineering lab equipment in India.

What Are Double Shear Test Specimens Used For?
In a double-shear test the specimen passes through a fixture so that its middle section is pushed one way while both ends are held, and it fails by shearing across two planes at the same time. The shear strength is the maximum load divided by twice the specimen's cross-sectional area, since two faces carry the load. Pins, rivets, bolts and clevis joints are loaded in just this way in real machines, so the test links classroom results to everyday design.
Copper is ductile, so students usually see the specimen bend and deform before it separates, and the sheared faces make a good discussion point. Because the diameter can fall anywhere between 5.65 and 6 mm, measure each specimen with a micrometer or vernier caliper before testing and use that value when working out the area. Each specimen is destroyed in the test, so plan one for every result you need.
What to Specify When Ordering
- The number of specimens — one per test, plus spares for practice runs
- The testing machine and shear fixture you will use, so we can confirm the specimens suit it
- Any other test specimens needed on the same quotation

Frequently Asked Questions
What are the Double Shear Test Specimens made of?
The Double Shear Test Specimens (SLE/ETP/07) are made of copper, a ductile metal that deforms noticeably before it shears, which makes the failure easy for students to observe and discuss.
What size are the Double Shear Test Specimens?
Each Double Shear Test Specimen is 50 mm long, with a diameter between 5.65 and 6 mm. Measure every specimen's actual diameter before testing, because the cross-sectional area is needed to calculate shear strength.
How is shear strength calculated from a double-shear test?
For Double Shear Test Specimens, divide the maximum load by twice the cross-sectional area worked out from the measured diameter. The factor of two appears because the specimen shears across two planes at the same time.
Which machine are the specimens used on?
The machine and fixture for the Double Shear Test Specimens are not specified on this page. Send your testing machine and shear fixture details through the contact page so we can confirm that the specimens are suitable.
Can a specimen be reused?
No. Each Double Shear Test Specimen is sheared through during the test and cannot be used again. Order one specimen for every test planned, with a few extra for demonstrations or repeat readings.
Who supplies the Double Shear Test Specimens?
The Double Shear Test Specimens are supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, from Ambala, Haryana, India, to engineering colleges, polytechnics, training institutes and dealers in India and international markets.
