Uburyo bwo gukora isuzuma ry’uburyo amazi anyuramo n’uburyo anyuramo | EN877:2021

Imiyoboro y'icyuma gikozwe mu cyumaGusuzuma uburyo bwo gufatana n'amazi ashyushye n'akonje bipimwa hakurikijwe EN877, cyane cyane kugira ngo harebwe uburyo bwo kurinda no kuramba kw'imiyoboro yabo irwanya ingese, cyane cyane mu gihe cy'imikorere nyayo. Ibi bizamini akenshi bibanda ku bipfuka bishyirwa imbere no hanze y'imiyoboro ya SML (nk'ama-resin epoxy, polyurethane, n'imirongo ya sima). Isuzuma ry'uburyo bwo gufatana ripima mu buryo butaziguye imbaraga z'imiyoboro iri hagati y'igipfuka n'icyuma cyo hasi cy'umuyoboro w'icyuma. Isuzuma ry'uburyo bwo gutwarana n'amazi ashyushye n'akonje ryerekana ihindagurika ry'ubushyuhe rigaragara ku miyoboro mu buryo nyabwo, rigasuzuma uburyo bwo kurinda burambye muri ubu buryo bwo kwirinda ingese buhindagurika.

Isuzuma ryo gufata nezaEse?

Uburyo irangi rifatana bugomba kugenzurwa gusa ku bipimo byavuye mu bicuruzwa byarangiye hakoreshejwe ikizamini cya crosscut hakurikijwe EN ISO 2409, muri ubu buryo bukurikira:

• Icyitegererezo cy'igerageza: igice cy'uburebure nibura mm 100 giciwe n'umuyoboro upfutse cyangwa igipfundikizo byaba byiza gifite nibura DN 100;
• umubare w'ibice: 6;
• Intera y'ibice: mm 2 (mm 3 ku bipfukisho bifite ubugari buke bwagenwe n'uwabikoze bungana cyangwa burenga µm 120);
• Ibisubizo bigomba guhuza n'Imbonerahamwe ya 1.

Imbonerahamwe ya 1:

Ubudahangarwa ku kuzenguruka kw'ubushyuhe

Ikizamini kigomba gukorwa gusa ku bipimo byavuye mu bicuruzwa byarangiye. Iteraniro ry'ikizamini rigomba gukorwa ku nshuro 1500 z'amazi ashyushye n'akonje hakurikijwe gahunda ikurikira:

a) (30 + 1) l y'amazi ku bushyuhe bwa (93 + 2) °C mu gihe cy'umunota 1, ku muvuduko uhoraho w'amazi,
b) igihe cyo kuruhuka no gusohora amazi cy'umunota 1;
c)(30 + 1) l y'amazi ku bushyuhe bwa (15 + 5)°C mu gihe cy'umunota 1, ku muvuduko uhoraho w'amazi,
d) igihe cyo kuruhuka no gusohora amazi cy'umunota 1

Ubushyuhe bw'amazi bugomba gupimwa aho binjirira.Urugero rw'uburyo ikizamini gisanzwe gitegurwa ruboneka ku Ishusho ya 3.

Nyuma yo guhagarika ikizamini, imiyoboro n'ibikoresho bigomba kozwa ako kanya kugira ngo haveho umwanda uwo ari wo wose. Hanyuma imiyoboro igomba gucibwamo ibice bibiri, hanyuma hagasuzumwa ibisigazwa by'imbere kugira ngo harebwe ingano y'ibisebe n'ingese bitagomba kurenza urugero rukurikira:

Ingano y'ibisebe: Ingano ya 3, icyiciro cya 3 nk'uko bivugwa muri EN IS0 4628-2:
Ingano y'ingese: Ri 2 nk'uko bivugwa muri EN IS0 4628-3.
