(Specification)Standard Specification for Leg Protection for Chain Saw Users
Standard Specification for Leg Protection for Chain Saw Users
SCOPE
1.1 This specification specified minimum requirements for the design, performance, testing, and certification of protective garments and protective devices designed to provide cut resistance protection to the legs of operators of power chain saws.
1.2 The object of this specification is to prescribe fit, function, and performance criteria for protective garments and protective devices that, when worn by chain saw operators, that are intended to reduce 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.
