Follow up includes ? Assuring that design requirements are achieved ? Review of engineering and design drawings ? Confirmation of incorporation into manufacturing ? Review the Control Plans and the Process FMEA 79 Revised RPN After actions are taken, estimate and enter the ratings for Severity, Occurrence and Detection. Calculate and enter the resulting RPN. If no actions are taken, these these columns blank. 80 DESIGN FMEA Case Study Exercise 81 Ac ti on Resul ts I tem Desc ripti on Fu ncti onPotenti alFa i l ureModePotenti alEffec t(s) ofFa i l ureSevClassPotenti alCause(s)/Mec hanis m(s)O f F ail ureOccurtCur ren tDesi gnContr olsDetecR.P.N.RemendedAc ti onsRespons i bil i ty Tar getCompleti onDateAc ti onsTa k en SevOccDetR.P.N.P art Nam e:Hite ch S wit chP art Num ber:HT 999 8 88ABP as scu rr e nt toCent rallight ing c ontro lFun ction:Gene ratesign al wh enactuateP iezo ele ctricsw it chcr y stalmat erial G ene rate si gnal when a ctuat eP iezo electri cCr y stalmat erialcrac ke dS witchfai ls t opas scu rr e nt77The s upp ortingsu rfac e f or t hecr y stal is t oosmallThe c rystalmat erial i sbritt le atambie nt tem p44S end t oce rtif ied labperfo rme d bentand t wi st testFor st re ssS witch t e stedat suppli erABCP as sed UL,CSA , S IS IRS tandar d3584140FE A anal y si s t oinc rea sesup po rt area t oev enlydistri bute loadev enly ac ro ssthe cr y stalsu rfac eRevis e sp ec t oinclu de l ab t estto desig n l oadto detect fai lur emodeat 20C + 5 CHiT ec h C rystalCom panyMr. Won g98 07 25HiT ec h C rystalCom panyMr. Won g98 07 25S uppo rt are ainc rea se f ro m S q. mm t o S q. mmRev.
