1 SCOPE This Standard provides performance and safety requirements for splitting wedges that are used specifi- cally for splitting wood. It is intended to serve as a guide in selecting, testing, and using the hand tools covered. It is not the purpose of this Standard to specify the details of manufacturing. This Standard is also meant to serve as a guide in developing manuals and posters and for training per- sonnel in safe practices. This Standard may be used as a guide bystate authori- ties or other regulatory bodies in the formulation oflaws or regulations. It is also intended for voluntary use by establishments that use or manufacture the tools cov- ered. The methods employed to ensure compliance with this Standard shall be determined by the proper regula- tory or administrative authority. 2 NORMATIVE REFERENCES The following documents form a part of this Standard to the extent specified herein.

(a) The struck face shall have a flat or convex shape. (b) The struck face of all wedges shall have a chamfer of approximately 45 deg (or equivalent radius) around the perimeter, with the lesser width equal to approxi- matelyone-tenthofthe minimumheadwidth. Forexam- ple, if the minimum head width equals 2 in. (50.8 mm), then the lesser chamfer width will equal approximately 0.2 in. (5 mm). (c) All wedges shall be free of nonfunctional sharp edges, points, and surface roughness that could inflict personal injury on the user when handling the tool. (d) Wedges shall pass the tests outlined in section 5. 4.2 Materials The materials used inthe manufacture ofwedges shall be such as to produce wedges conforming to the require- ments specified herein. 4.3 Mechanical Properties The hardness of the wood-splitting wedges shall not exceed 35 HRC or equivalent. 5 TESTS Many tests required herein are inherently hazardous, and adequate safeguards for personnel and property shall be employed in conducting such tests. Separate (new) wedges shall be used for each test. Failure to meet the requirements of either test indicates that the wedges do not comply with this Standard. 5.1 Hardness Determination Test Hardness determination shall be made on a fixtured wood-splitting wedge or on a mounted or unmounted specimen that has been cut from the tool using the wet abrasive or other equivalent method. Any hardness test will be acceptable that uses equipment and methods equivalent to Rockwell hardness determination as speci- fied in ASTM E 18.
6 SAFETY REQUIREMENTS AND LIMITATIONS OF USE Instructors and employers shall stress proper and safe use of wedges and shall emphasize the need to wear and ensure the use of safety goggles. The publication Guide to Hand Tools —Selection, Safety Tips, ProperUse and Care provides guidelines for the safe use of these tools. (a) Wood-splitting wedges are special-purpose tools designed and intended only for use in splitting wood. (b) Wood-splitting wedges shall not be struck with an ax or hatchet. (c) A blow from an appropriate striking tool shall be struck squarely, with the striking face parallel with a struck face of the wedge. Glancing blows, overstrikes, and understrikes should be avoided. An appropriate striking tool shall be a sledge or wood- chopper’s maul with a strikingface notless than0.375 in. (9.53 mm) larger in diameter than the struck face of the wood-splitting wedge.
