Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONThe need for a systematic means of evaluating

3、engineered wood fiber for use as a playground safetysurface from the standpoint of particle size, consistency, purity, and ability to drain, has become agrowing concern of the designers, operators, and manufacturers of engineered wood fiber systems.There has been no qualitative method to assess thes

4、e parameters of engineered wood fiber (that is,particle size, consistency, purity, and ability to drain) to ensure its quality. Therefore, the goal of thisspecification is to establish a uniform means to measure the characteristics of engineered wood fiberin order to provide the potential buyer with

5、 performance specifications to select an engineered woodfiber suitable to meet the needs of playground designers, operators and manufacturers.1. Scope1.1 This specification establishes minimum characteristics for those factors that determine particle size, consistency, purity, andability to drain.1.

6、2 Engineered wood fiber that meets the requirements of this specification must comply with Specification F1292, if the surfaceis in the use zone as defined in Specification F1487.1.3 A sample of wood fiber that meets the requirements of this specification may be designated engineered wood fiber and

7、besuitable for playground safety surfacing.1.4 This specification does not imply that an injury cannot be incurred if the engineered wood fiber complies with thisspecification.1.5 To meet the requirements of this specification, the material shall perform as follows:1.5.1 The material shall meet part

8、icle size requirements.1.5.2 The material shall meet the requirement for metal particles.1.5.3 The material shall meet the allowable heavy metal concentrations considered hazardous to children.1.5.4 The material shall meet the requirements of Specification F1292.1.6 The values stated in inch-pound u

9、nits are to be regarded as standard. The values in parentheses are mathematicalconversions. SI units, which are provided for information, are not considered the standard, except in 8.4.1.7 WarningMercury has been designated by EPA and many state agencies as a hazardous material that can cause centra

10、lnervous system, kidney, and liver damage. Mercury, or its vapor, may be hazardous to health and corrosive to materials. Cautionshould be taken when handling mercury and mercury-containing products. See the applicable product Material Safety Data Sheet(MSDS) for details and EPAs website (http:/www.e

11、pa.gov/mercury/faq.htm) for additional information. Users should be awarethat selling mercury or mercury-containing products, or both, in your state may be prohibited by state law.1.8 The following precautionary statement pertains to the test method portions only, in 7.4, 8.4, and 9.4 of this specif
