ASTM D1037 Wood-Base Fiber and Particle Panel Strength Testing

ASTM D1037 | Wood-Base Fiber and Particle Panels | Strength Testing

1. Static Bending
   1. Prepare the specimens as described in the test method – using specimens cut from both directions with respect to original board, in dry and soaked conditions.
   2. Mount the specimen in a 3-point (center loading) fixture. Selection of the proper fixture span, supports, and loading nose will depend on specimen size and condition.
   3. Apply load to the center of the specimen at the constant rate of speed calculated from the equation in the standard.
   4. Continue the test until rupture, while recording all force vs. deflection data.
   5. Typical Calculations: Modulus of Rupture, Stiffness (Apparent Modulus of Elasticity)
2. Tensile Strength Parallel to Surface (dog-bone specimens)
   1. Prepare the specimens as described in the test method – using dog-bone shapes cut from both directions with respect to original board, in dry and soaked conditions.
   2. Mount the specimens in self-aligning and self-tightening grips.
   3. Apply a tensile load at the constant rate of speed specified in the standard.
   4. Continue loading until failure.
   5. Calculations: Max Load, Max Stress
3. Tensile Strength Perpendicular to Surface (block-type specimens)
   1. Prepare the specimens as described in the test method – dry condition only.
   2. Bond the test specimen to test blocks on both sides and mount the assembly into the appropriate loading fixtures.
   3. Apply a tensile load at the constant rate of speed specified in the standard.
   4. Continue loading until failure.
   5. Calculations: Max Load, Max Stress
4. Compression Strength Parallel to Surface
   1. Determine the Procedure within this method that best matches your test material characteristics: Procedure A (Laminated Specimen), Procedure B (Lateral Support), or Procedure C (Short Column).
   2. Prepare the specimens as described in the test method and selected procedure – both in the dry and soaked conditions.
   3. Load the specimens into the test machine, centered underneath a spherically seated compression platen.
   4. Apply a compressive load at the constant rate of speed specified in the standard.
   5. Continue loading until failure.
   6. Calculations: Max Stress (Crushing Strength), Modulus of Elasticity
5. Other test procedures within ASTM D1037 that could be performed using a universal testing machine include:
   1. Lateral Nail Resistance
   2. Nail Withdrawal
   3. Nail Pull-Through
   4. Direct Screw Withdrawal
