Designation: E562-11 Standard Test Method for Determining Volume Fraction by Systematic Manual PointCount1
1. Scope
1.1 This test method describes a systematic manual pointcounting procedure for statistically estimating the volumefraction of an identifiablc constitucnt or phasc from sectionsthrough the microstructure by means of a point grid.
1.2 The use of automatic image analysis to delermine thevolume fraction of constituents is described in Practice E1245.
1.3 The valucs statcd in Sl units are to be regarded asstandard. No other units of measurement are included in thisstandard.
1.4 This stavddard does nor puarport to address all of rhesafety concerns. if any. associated wirh irs use. It is rhere spovasibiliry of the user of this scandard to esitcblish appro-priete safery cand heeairha pracrices candd deternnie the applica-bility of vegulatovy limitations prior to use.
