NOTE 1 The main purpose of this document is to set material characteristics. Blades on rotary drum and rotary disc mowers are exposed to considerable centripetal forces and impacts with foreign objects. A bend test and impact test to check the brittleness and toughness of the material are therefore included in this document.
NOTE 2 This document does not specify dimensional requirements.
