Pankhani ya zingwe zamagetsi, chitetezo ndi magwiridwe ake ndizofunikira kwambiri. Ichi ndichifukwa chake zigawo zosiyanasiyana zimakhala ndi zotsimikizira zawo kuti zitsimikizike kuti zingwe zimakwaniritsa mfundo zofunika.
Awiri mwa njira zodziwika bwino kwambiriUl (ma laobories olemba)ndiIEC (Internet Enterrotechnical Commission).
- ULimagwiritsidwa ntchitokumpoto kwa Amerika(USA ndi Canada) ndi kuyang'anaChitetezo.
- IECndipadziko lonse lapansi(wamba)Europe, Asia, ndi Misika ina) Izi zimatsimikizira onsemagwiridwe antchito ndi chitetezo.
Ngati ndinuWopanga, wotsatsa, kapena wogula, kudziwa kusiyana pakati pa miyezo iwiriyi ndizofunika posankha zingwe zoyenera m'misika yosiyanasiyana.
Tiyeni tidutse pamtundu waukulu pakatiUl ndi IEC MiyezoNdi momwe zimakhudzira kapangidwe kake, chiphaso, ndi ntchito.

✅Ul ali ndi mayeso owoneka bwino, komaIEC imathandizira othamanga ocheperako ndi chingwe chopanda malire.
✅Chitsimikizo cha Ul chimafuna kuvomerezedwa mwachindunji, pomweKutsatira kwa Iec kumasiyana ndi malamulo am'deralo.
