Oprema za obločno varjenje - 14. del: Umerjanje, validacija in preskušanje skladnosti (IEC 60974-14:2018)
Ta del standarda IEC 60974 določa zahteve za VERIFIKACIJO opreme za obločno varjenje in zunanji nadzor. Ta dokument se uporablja tudi za praktično izvajanje postopka VERIFIKACIJE opreme za obločno varjenje.
Ta dokument je mogoče uporabiti v času namestitve in v vseh drugih časovnih presledkih ali intervalih, ki jih določi uporabnik, ki želi zagotoviti, da oprema obratuje v skladu s proizvajalčevimi specifikacijami ali drugimi uporabniško določenimi specifikacijami.
Ta dokument se ne uporablja za:
– plazemske sisteme, ki se uporabljajo za rezanje in dolbenje;
– naprave za obločne udare in stabilizacijo;
– opremo za obločno varjenje, izdelano v skladu s standardom IEC 60974-6.
OPOMBA 1: Druge komponente v varilnih sistemih, kot so npr. roboti, naprave za obračanje, plinske konzole itd., ravno tako vplivajo na rezultat varjenja in jih je mogoče po potrebi verificirati. Dodatne informacije so navedene v standardu ISO 17662.
OPOMBA 2: Redni pregledi in preskušanje opreme za obločno varjenje so zajeti v standardu IEC 60974-4.
Ta dokument velja za uporabnika, servisno delavnico ali proizvajalca. Dokument je mogoče uporabiti – samostojno;
– v povezavi z navodili proizvajalca; ali
– kot podlago za enakovreden postopek VERIFIKACIJE, ki ga je za določeno opremo pripravil proizvajalec.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
