(Specification)Standard Specification for Foot Protection for Chain Saw Users
Standard Specification for Foot Protection for Chain Saw Users
SCOPE
1.1 This specification covers minimum requirements for the design, performance, testing, and certification of footwear and foot protective devices designed to provide cut resistance protection to the feet of operators of power chain saws.
1.2 The objective of this specification is to prescribe fit, function, and performance criteria for footwear and foot protective devices, worn by chain saw operators, which are intended to reduce foot injuries caused by contact with a running power saw chain.
1.3 This specification is not intended to serve as a detailed manufacturing or purchasing specification, but it 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 specification 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 the word shall; recommendations and advisory information is indicated by the use of the word should.
