1、Designation: F2892 11Standard Specification forPerformance Requirements for Soft Toe Protective Footwear(Non-Safety / Non-Protective Toe)1This standard is issued under the fixed designation F2892; the number immediately following the designation indicates the year oforiginal adoption or, in the case
2、 of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONCurrent ASTM standards F2412 and F2413 provide test methods and performance requirements for
3、footwear requiring a protective safety toe cap. In industry there are many jobs that do not require toeprotection from impact or compression. This committee has developed non-safety toe cap (soft toe)requirements to allow manufacturers to demonstrate the performance level of non-safety toe cap (soft
4、toe) footwear.1. Scope1.1 The principle purpose of this specification is the certi-fication of protective footwear. Certification must be performedby independent third party laboratories in order for footwear tobare the ASTM marking.1.2 The specification contains performance requirements forfootwear
5、 to protect workers feet from the following hazardsby providing: (1) conductive properties (Cd) which reducehazards that may result from static electricity buildup; andreduce the possibility of ignition of explosives and volatilechemicals; (2) electric hazard protection (EH), to protect thewearer wh
6、en accidental contact by stepping on live electricwires; (3) static dissipative properties (SD) to reduce hazardsdue to excessively low footwear electrical resistance that mayexist where SD footwear is required; (4) puncture resistance(PR) footwear devices.1.3 This specification covers minimum requi
7、rements for theperformance of footwear to provide protection against a varietyof workplace hazards other than the toe area that can poten-tially result in injury.1.4 This specification is not intended to serve as a detailedmanufacturing or purchasing specification, but can be refer-enced in purchase
8、 contracts to ensure that minimum perfor-mance requirements are met.1.5 Controlled laboratory tests used to determine compli-ance with the performance requirements of this specificationshall not be deemed as establishing performance levels for allsituations to which individuals may be exposed.1.6 An
9、y changes to the original components of safetyfootwear such as replacing or adding after market footbeds/inserts could cause failure to any or all parts, or a combinationthereof, of this specification rendering the ASTM Soft ToeProtective Footwear label invalid.1.7 The values stated in SI units are
10、to be regarded asstandard. No other units of measurement are included in thisstandard.1.8 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices a
