This standard specifies the requirements for a double-bit axe intended for use in fighting forest fires. It covers the material, dimensions, mass, construction, hardness, and performance tests for both the steel axe head and its wooden handle, ensuring its suitability and durability for clearing and chopping tasks during firefighting operations.

Practical Notes
This axe is specifically designed for clearing fire lines by chopping wood and undergrowth; it is not intended for heavy-duty felling or splitting.
Ensure the axe head is securely fixed to the handle without any wobble before use, as specified in the handle tests (Clause 8.2).
The specified hardness (52-58 HRC) provides a balance between edge retention and toughness, preventing the edge from chipping easily on impact.
