ASTM F 1914 : 2018 : REDLINE

.1 This test method covers procedures to determine shorttermindentation and residual indentation of resilient flooring,when subjected to concentrated loads.1.2 The test methods appear in the following order:SectionIndentation by McBurney2 Test 4 to 10Indentation and Residual Indentation 11 to 151.3 There are two procedures with their respective apparatus.The first (McBurney Test) is described in Sections 4 to 10and is restricted to a spherical foot. It is only used for initialindentation measurements of VCT. The second is described inSections 11 to 15 and has interchangeable feet with variablegeometry. It is used to measure initial and residual indentation.1.4 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use.
