ASTM F2232-2003 Standard Test Method for Determining the Longitudinal Load Required to Detach High Heels from Footwear《从鞋靴上除去高跟所要求的纵向负荷测定的标准试验方法》.pdf

1、Designation: F 2232 03Standard Test Method forDetermining the Longitudinal Load Required to Detach HighHeels from Footwear1This standard is issued under the fixed designation F 2232; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision,

2、the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This method covers the determination of the forcerequired to detach the heel from footwear through the ap

3、pli-cation of longitudinal tensile force at a constant displacementrate. The longitudinal test force simulates the most commonheel failure mode. Heel height of 20 mm (1316 in.) or larger isneeded to perform this test method properly. Most womensmedium and high heeled footwear meets this requirement.

4、1.2 The values stated in SI units are to be regarded as thestandard. The values given in parentheses are for informationonly.1.3 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 app
