What is ASTM D905?
ASTM D905 is a testing standard that evaluates the shear strength of adhesives used for bonding wood materials.
Why is ASTM D905 Important?
✅ Assesses wood adhesive performance for construction and furniture applications.
✅ Ensures strong, durable bonding as an alternative to bolts and screws.
✅ Helps manufacturers optimize adhesive formulations.
ASTM D905 Testing Method
Test Specimen
🪵 Material: Wood or similar bonded materials.
🧩 Shape: Two equal-sized rectangular blocks staggered by ¼ inch and bonded together.
Testing Equipment
🔹 Shear Test Fixture – Applies a compressive load to generate shear stress.
🔹 Guillotine-Type Load Application – Ensures consistent shear force.
Recommended UTMs
Machines with a force capacity of 5kN to 600kN are ideal for ASTM D905 testing.
VEW 2308 – Universal Testing Machine
✅ High-precision electronic motor for controlled testing.
✅ Performs shear, tensile, compression, bending, and peel tests.
✅ Suitable for wood, rubber, textiles, aerospace materials, and more.
ASTM D905 Test Procedure
1️⃣ Condition test specimens as per ASTM D905 requirements.
2️⃣ Secure the specimen in a shear tool on a UTM machine.
3️⃣ Apply a compressive load at a constant rate.
4️⃣ Continue loading until failure.
Key Measurement in ASTM D905
📌 Shear Stress – Determines adhesive resistance to shear forces.
