: Chizindikiro cha mamita

*Chizindikirocho chimasindikizidwa mita imodzi iliyonse;

● Mtundu wa chizindikiro ndi woyera, koma ngati kulembanso ndikofunikira, chizindikiro chachikasu chiyenera kusindikizidwa mwatsopano pamalo ena.
● Kusamveka bwino kwa kutalika kwa chizindikiro nthawi zina kumaloledwa ngati zizindikiro zonse ziwiri zapafupi zili zomveka bwino;
● Malekezero onse awiri a chingwe amatsekedwa ndi zipewa zotenthetsera kuti madzi asalowe.

Kulongedza

● Chingwe chilichonse chautali chiyenera kuzunguliridwa pa Drum yapulasitiki.

● Utali wa ng'oma: Utali wa ng'oma wamba ndi 3000m±2% kapena kapangidwe kake malinga ndi funso la kasitomala;

Kulemba ng'oma (chitini malinga ndi zofunikira mu ukadaulo)

-Dzina la wopanga;
-Kupanga chaka ndi mwezi;
-Muvi wozungulira;
-Malo akunja a chingwe omwe akusonyeza muvi;
-Mawu akuti “CHINYAMBO CHA ULUWALA WA MACHONSE”;
-Mtundu wa chingwe ndi kukula kwake;
-Nambala ya ng'oma;
-Utali wa ng'oma;
-Kulemera konse / konse;
-Chiyambi, Mawu akuti "WOPANGIDWA KU CHINA";
-Mbale yochenjeza yosonyeza njira yoyenera yokwezera, kutsitsa ndi kutumiza chingwecho;
-Zina zokhudza makasitomala monga nambala ya mgwirizano, nambala ya polojekiti, ndi komwe katunduyo akupita. (ngati pakufunika)

Zikalata zozindikiritsa chingwe

-Satifiketi yovomerezeka ya malonda;
-Lipoti la mayeso.
