procedure.

o 5++ va+id indications formed by magnetic partic+e eamination are t*e resu+t of

magnetic f+u +ea7age fie+ds. Indications may be Re+evant or Non Re+evant.

o Indications caused by partic+es being *e+d by non magnetic force are fa+se,

eamp+es inc+ude partic+es +ying in t*e depression at t*e side of a we+d, or partic+es

wedged to t*e sca+e on t*e surface.

o Re+evant Indications produced by f+u +in7age fie+ds w*ic* are t*e resu+ts of

discontinuities t*at may or may not be acceptab+e and s*a++ be eva+uated wit*

regards to t*e acceptance standard.

o Non Re+evant Indications can occur sing+y or in pattern as a resu+t of f+u +ea7age

fie+ds created by conditions suc* as c*anges in section, in*erent properties, etc., or

may be associated wit* a discontinuity, w*ic* is not considered detrimenta+ to t*e part.

wit*out tai+ t*e +engt* e/ua+ to or +ess t*an t*ree times t*e widt*.

o oca+i@ed surface imperfections, w*ic* may occur from mac*ining mar7s, surface

conditions, or incomp+ete bond between base meta+ and c+adding, may produce

simi+ar indications, w*ic* are non#re+evant to t*e detection of unacceptab+e
