Permissible Tolerance for Length:
- According to IS 3129-1985, the permissible tolerance for the length of finished boards is ±6 mm. This ensures that the boards meet certain dimensional standards required for their application.
Other Important Specifications:
- Thickness Tolerance:
- The standard allows a thickness tolerance of ±5 percent for boards.
- Width Tolerance:
- The permissible tolerance for the width of finished boards is ±3 mm.
- Edge Straightness and Squareness:
- Edge straightness: 2 mm per 1,000 mm or 0.2 percent.
- Squareness: 2 mm per 1,000 mm or 0.2 percent.
Purpose of These Specifications:
- Ensuring dimensional accuracy and consistency helps maintain the structural integrity and performance of the particle boards.
- Controlling the moisture content and density is crucial for the boards' durability, stability, and suitability for various applications.
