(Specification)Standard Specification for Leg Protection for Chain Saw Users
Standard Specification for Leg Protection for Chain Saw Users
ABSTRACT
This specification prescribes the minimum requirements for the design, performance, testing, and certification of protective garments and protective devices that, when worn by operators of power chain saws, shall provide cut resistance protection to their legs, and thereby reducing leg injuries caused by close contact with the running chain saw. The protective garments and devices shall be constructed with suitable fit and flexibility so as to provide sufficient leg comfort and normal maneuverability to perform intended tasks, while maintaining satisfactory functionality and efficacy for the duration of its regular use throughout seasonal climatic variations. Completed garments shall be inspected and certified as specified, and maintained in accordance with the manufacturer's instructions.
SCOPE
1.1 This specification specifies minimum requirements for the design, performance, testing, and certification of protective clothing and protective devices designed to provide cut resistance protection to the legs of operators of power chain saws.
1.2 The objective of this specification is to prescribe fit, function, and performance criteria for protective clothing and protective devices that, when worn by chain saw operators, are intended to reduce the severity of leg injuries caused by contact with a running power saw chain.
1.3 This standard is not intended to serve as a detailed manufacturing or purchasing specification, but can be referenced in purchase contracts to ensure that minimum performance requirements are met.
1.4 Controlled laboratory tests used to determine compliance with the performance requirements of this standard shall not be deemed as establishing performance levels for all situations to which chain saw operators may be exposed.
1.5 Mandatory requirements are indicated by the use of “shall”; recommendations and advisory information is indicated by use of “should.”
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
