1、Designation: F2075 10An American National StandardStandard Specification forEngineered Wood Fiber for Use as a Playground SafetySurface Under and Around Playground Equipment1This standard is issued under the fixed designation F2075; the number immediately following the designation indicates the year

2、 oforiginal adoption or, in the case 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.INTRODUCTIONThe need for a systematic means of evaluating engineered

3、 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 these paramete

4、rs 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 performan

(A constant moisture level isnecessary to pr

46、event weight changes due to changing moisturelevels in the sample).7.3.3 The wood fiber sample was reduced in overall size tofacilitate testing using a standard 2-in.-deep 8-in.-diametersieve. Because of the light weight of wood fiber, the oven driedsample weight of individual samples to be tested s
