This standard prescribes the requirements and methods of test for wood wool intended for general packaging purposes. It specifies acceptable limits for dimensions, moisture content, dust percentage, and pH value to ensure the material provides adequate cushioning without promoting corrosion or fungal growth.
wood wool for general packaging purposes
Quick Reference Values
Maximum moisture content15 percent by mass
Maximum dust and small pieces (passing 2.00-mm IS Sieve)1 percent by mass
pH of aqueous extract4.5 to 8.0
Maximum width of strands3.0 mm
Maximum thickness of strands0.5 mm
Key Formulas
Moisture Content (%) = [(W1 - W2) / W2] x 100 — where W1 is initial mass and W2 is oven-dry mass
Practical Notes
Strictly monitor the pH value of wood wool if it is being used to pack bare metallic items, as acidic wood wool can accelerate corrosion.
Ensure moisture content is well within the 15% limit before packing; otherwise, fungal growth and rotting can compromise both the packaging and the contents.
Wood wool should be tightly baled for transport, but excessive crushing that leads to dust generation exceeding 1% should be avoided.
