PRESKUŠANJE INDUSTRIJSKEGA NAPAJALNIKA SKLADNO Z MEDNARODNIMI STANDARDI IN PRIPOROČILI

IVEC, ALEŠ (avtor), Begeš, Gaber (mentor)

Zaradi različnih varnostnih zahtev mednarodne skupnosti ter dodatnih zahtev pri posameznih državah, se proizvajalci srečujejo z različnim izzivi pri lansiranju določenih proizvodov na trge. Poleg mednarodne standardizacije se proizvajalci pogosto srečujejo tudi z dodatnimi zahtevami posameznih nacionalnih certifikacijskih organov. Proizvodi, kjer so te zahteve zelo kompleksne so na primer napajalniki (bodisi za vgradnjo ali za neposreden priklop). Zaradi tega sem izbral ta proizvod kot osnovo za napisano diplomsko delo. Znotraj službenih zadolžitev sem samostojno opravil projekt preizkušanja stikalnega napajalnika v skladu z zahtevami evropskih ter mednarodnih standardov. Hkrati pa sem upošteval tudi specifike za vstop na severnoameriški trg. Na osnovi praktičnega primera sem opisal celoten projekt od določanja pravega standarda, določanja možnih točk standardov, vključevanje dodatnih mednarodnih zahtev ter pripravo končne projektne dokumentacije. Vključil sem tudi obrazložitev dejanskih tehničnih zahtev standarda, hkrati pa tudi ustrezno prikazal lastne merilne rezultate izvedenih postopkov. Znotraj dela sem obrazložil tudi same specifike dejavnosti preizkušanja in certifikacije proizvodov, okvirno opisal zahteve produktnega standarda IEC 60950-1, ki je bil v tem primeru uporabljen ter predstavil tudi mednarodno certifikacijsko shemo CB. Zraven sem upošteval zahteve UL 60950-1 ter CAN/CSA-C22.2 No. 60950-1, ki sta harmonizirana z IEC 60950-1. Izdaja certifikatov v skladu z zahtevami CB sheme je v izbranem primeru omogočila proizvajalcu nadaljevanje in vstop na severnoameriški trg, preko izvedbe dodatne UL in CSA certifikacije. Merilni rezultati in pripravljeno poročilo iz moje strani je torej služilo kot osnova za vse nadaljnje postopke. Poleg opisanih metod, postopkov in pridobljenega znanja iz tehnične izvedbe preizkusov, sem se poglobil tudi v problematiko mednarodne standardizacije, s katero se vse pogosteje spopadajo proizvajalci.

Manufacturers face different challenges when launching certain products on the market due to different safety requirements of the international community and additional requirements of individual countries. In addition to the international standardisation, the manufacturers also often face additional requirements of specific national certification bodies. Products with very complex requirements are, for example, power supplies (either for installation or for a direct connection). Because of this I chose this product as the basis for my dissertation. I independently carried out the testing of the switch mode power supply in accordance with the requirements of European and international standards. At the same time, I also took into account specifics for the entry into the North American market. I described the whole project on the basis of a practical example, from determining the right standard, determining possible points of the standards, the integration of additional international requests to the preparation of the final project documentation. I also included the explanation of actual technical requirements of the standards. I have also appropriately displayed personal measuring results of the procedures I performed. In the dissertation I explained the specifics of testing and the certification of products, I roughly described the requirements of the international standard IEC 60950-1 that was in this case used. I also introduced the international certification scheme CB. I took into account the requirements of UL 60950-1 and CAN/CSA-C22.2 No. 60950-1, both of which are harmonised with IEC 60950-1. The issuing of the certificates in accordance with the requirements of the CB scheme has, in the selected example, allowed the manufacturer the continuation and entry into the North American market through the implementation of the additional UL and CSA certification. The measured results and the prepared report from my side served as a basis for all further procedures. In addition to the described methods, procedures and the acquired knowledge from the technical test-performance, I also focused on the problems of international standardisation which many manufacturers increasingly face.
