Practical Notes

The grain of the wood for the head should run parallel to the axis of the handle to prevent splitting.

Ensure mallets are stored in a dry place to maintain the timber's moisture content below the 12% limit, preventing cracks and deformation.

The standard is intended for quality control and procurement of these specific tools, ensuring interchangeability and performance.
