This new edition can els an re laces the f irst edition of IEC 6 7 0, publs ed in 19 8 It
con titutes a tec nical revision It also s p rsedes IEEE Std 3 3-2 0
The main tec nical c an es with regard to IEC 6 7 0:19 8 are as fol ows:
• to harmonize in a u iq e stan ard q al f i ation practices formerly given by
IEC 6 7 0:19 8 an IEEE Std 3 3-2 0 on initial q al f i ation,
• to take into ac ou t the ne d to re s es an exten the q al fied lf e of electrical

This revision in orp rates c r ent practices an les on le rned fom the implementation of
previou version of this stan ard by the n cle r in u try
Several is ues are clarified or c an ed in this revision:
• This stan ard defines the method f or eq ipment q al fication when it is desired to q al fy
eq ipment for the a pl cation in the en ironments to whic it may b exp sed This
standard is general y uti zed for q al fication of al electrical eq ipment imp rtant to saf ety
in ac ordan e with IAEA terminolog The doc mentation an test req irements are,
however, more rigorou for eq ipment located in a hars en ironment
• The test margin have b en updated to b t er identify the p rameters that ac ieve test
margin on desig b sis event profi es
• An imp rtant con e t in eq ipment q al f i ation is the recog ition that sig if i ant
degradation could b cau ed by agein mec anisms oc ur in f om the en ironments
d rin the service l f e, an therefore eq ipment imp rtant to saf ety s ould b brou ht to
the en of q al fied lfe (o eratin agein ) prior to imp sin desig b sis event
simulation Previou version recog ised that the p riod of time f or whic ac e ta le
p r orman e was demon trated is the q al fied l fe The q al fied lfe do s not in lu e the
time d rin or af ter the ac ident con ition f or whic q al fication is demon trated
(mis ion time) The con e t of q al fied l fe contin es in this revision This revision also
recog ises that the con ition of the eq ipment for whic ac e ta le p rf orman e was
demon trated is the q alfied con ition Th s, new lcen e renewal an lf e exten ion

A typ test s bjects a re resentative sample of eq ipment, in lu in its interf aces, to a series
of tests, simulatin the ef fects of sig if i ant agein mec anisms d rin normal o eration
Eq ipment q alf i ation testin s al b p rformed with eq ipment f un tionin in a state
