GB20052-2020 isanzwe isanzwe ibika ingufu zingufu zikoreshwa muburyo bwa kabiri bwumwanya wumuyaga ufite ibyiza byo guhangana ningaruka zumuzunguruko mugufi, imirimo ntoya yo kubungabunga, gukora cyane, gukora bike, urusaku ruto, urusaku ruto, akenshi bikoreshwa mumuriro, ibimenyetso biturika nibindi bibanza bikenewe cyane. Umutekano, gukumira umuriro, nta mwanda, urashobora gukoreshwa mu buryo butaziguye amashanyarazi aremereye;
Ukoresheje tekinoroji yiterambere ryimbere mu gihugu, imbaraga zumukanishi mwinshi, imbaraga zikomeye zumuzunguruko, gusohora kworoheje, gusohora neza kwumuriro, kwizerwa cyane, kuramba kuramba;
Igihombo gito, urusaku ruke, ingaruka zo kuzigama ingufu ziragaragara, nta kubungabunga;
Imikorere myiza yo gukwirakwiza ubushyuhe, imbaraga ziremereye cyane, imbaraga zo gukonjesha ikirere zirashobora kuba igihe gito ibikorwa bidasanzwe;
Hamwe nimikorere runaka itagira ubushuhe, irashobora gukorera mubidukikije bikabije byubushuhe bwinshi;
Transformer yumye irashobora kuba ifite sisitemu nziza yo kumenya ubushyuhe no kurinda. Ukoresheje ibimenyetso byubwenge bwo kugenzura ubushyuhe, birashobora guhita bitahura no kwerekana ubushyuhe bwakazi bwibice bitatu byizunguruka, birashobora guhita bitangira, guhagarika umuyaga, no gutabaza, urugendo nibindi bikorwa byo gushiraho;
Ingano ntoya, uburemere bworoshye, umwanya muto, igiciro gito cyo kwishyiriraho.
