Imiterere yo kubika imiyoboro idafite ibyuma

Hitamo ahabigenewe no mububiko:

1) Ikibanza cyangwa ububiko bubitswemo ibyuma bigomba gusukurwa no kuvanwa, kure yinganda na mine bitanga imyuka yangiza cyangwa ivumbi.Kuraho ibyatsi n'imyanda yose kurubuga kugirango ibyuma bisukure;

2) Ntugashyire ibikoresho byangiza ibyuma, nka aside, alkali, umunyu cyangwa sima, mububiko.Ubwoko butandukanye bwibyuma bigomba gutondekwa ukundi kugirango birinde urujijo no kwirinda kwangirika;

3) Ibyuma binini, gari ya moshi, ibitutsi by'icyuma, umuyoboro w'icyuma kinini cya diameter, kwibagirwa, n'ibindi birashobora gushyirwa mu kirere;

4) Ibyuma bito n'ibiciriritse, ibyuma, insinga, icyuma giciriritse, umuyoboro wibyuma, umugozi wibyuma nu mugozi wibyuma, nibindi, birashobora kubikwa mumasuka ahumeka neza, ariko bigomba gushyirwa kuruhande;

5) Bimwe mu byuma bito, ibyuma bito, ibyuma, ibyuma bya silikoni, diameter nto cyangwa uruzitiro rukomeye, ibyuma bitandukanye bikonje bikonje kandi bikonje bikonje, hamwe nibicuruzwa bihenze cyane, byangirika bishobora kubikwa mububiko;

6) Ububiko bugomba gutoranywa ukurikije imiterere y’imiterere, muri rusange hagakoreshwa ububiko rusange bufunze, ni ukuvuga ububiko bufite urukuta, inzugi n’amadirishya birakomeye, kandi hagatangwa ibikoresho byo guhumeka;

7) Ububiko bugomba kwitondera guhumeka kumunsi wizuba, kwitondera gufunga ubushuhe kumunsi wimvura, kandi buri gihe bikabika ahantu heza ho guhunika.
