Checking

Definition

Checking refers to short, shallow cracks on the surface of a material. When checking refers to wood, it is due to shrinkage.

Purpose

The purpose of recognizing checking is to identify potential issues with the integrity and appearance of materials, particularly wood, which can affect the quality and durability of the final product.

Examples of Use

1. Lumber Inspection: Detecting checks in wooden planks that may compromise structural integrity or aesthetics.
2. Furniture Making: Noting checks on the surface of wood that need to be addressed before finishing.
3. Construction: Observing checks in timber used for framing or other structural components.

Related Terms

• Cracking: A more severe form of checking where the cracks penetrate deeper into the material.
• Warping: The distortion of wood due to uneven drying or moisture content, often occurring alongside checking.
• Splitting: When wood fibers separate along the grain, usually more extensive than checking.

Notes

• Checking often occurs when wood dries too quickly or unevenly.
• Proper drying and seasoning of wood can help minimize checking.
