Ibipimo bya EN877 byerekana imikorere isabwaguta imiyoboro y'icyuma, Ibikoreshonaabahuzaikoreshwa muri sisitemu yo gukuramo amazi mu nyubako.EN877: 2021ni verisiyo iheruka yubusanzwe, isimbuza verisiyo yabanjirije EN877: 2006. Itandukaniro nyamukuru hagati yuburyo bubiri mubijyanye no kwipimisha nibi bikurikira:
1. Ikizamini:
EN877: 2006: Ahanini igerageza imiterere yubukanishi hamwe nimiterere yikimenyetso cyimiyoboro.
EN877: 2021: Hashingiwe ku kizamini cyambere, hiyongereyeho ibisabwa kugirango ikoreshwe mu majwi, kurwanya ruswa y’imiti, kurwanya umuriro n’ibindi bice bya sisitemu.
2. Uburyo bwo kugerageza:
EN877: 2021 ivugurura uburyo bumwe bwikizamini kugirango burusheho kuba siyansi kandi yumvikana, nka:Ikizamini cyo kurwanya ruswa ya chimique: Uburyo bushya bwo gupima nuburyo bwo kwipimisha burakoreshwa, nko gukoresha umuti wa pH2 sulfurike acide aho gukoresha aside hydrochloric yumwimerere, no kongeramo ibizamini byo kurwanya ruswa kumiti myinshi.
Ikizamini cyimikorere ya Acoustic: Hiyongereyeho ibisabwa kugirango ikoreshwe ryijwi rya sisitemu yimiyoboro, nko gukoresha uburyo bwumuvuduko wijwi kugirango bapime amajwi ya sisitemu.
Ikizamini cyo gukora umuriro: Wongeyeho ibisabwa kugirango ikizamini cyo kurwanya umuriro cya sisitemu y'imiyoboro, nko gukoresha uburyo bwo kurwanya umuriro kugira ngo ugerageze ubusugire bwa sisitemu y'imiyoboro mu bihe by’umuriro.EN877: 2021 ikoresha irangi hamwe nicyiciro cyo kurwanya umuriro A1
3. Ibisabwa mu bizamini:
EN877: 2021 yongereye ibisabwa mubizamini bimwe mubikorwa byerekana, nka:Imbaraga zikomeye: ziyongereye kuva kuri MPa 150 zigera kuri 200 MPa.
Kurambura: byiyongereye kuva kuri 1% bigera kuri 2%.
Kurwanya ruswa ya chimique: Hiyongereyeho ibisabwa byo kurwanya ruswa kubintu byinshi bya chimique, nkibisabwa kurwanya ruswa kubintu bya alkaline nka hydroxide ya sodium na hydroxide ya potasiyumu.
4. Raporo y'ibizamini:
EN877: 2021 ifite ibisabwa bikomeye kubirimo n'imiterere ya raporo y'ibizamini, nka:Irasaba raporo yikizamini gushyiramo amakuru arambuye nkuburyo bwikizamini, imiterere yikizamini, ibisubizo byikizamini, nu myanzuro.
Raporo y'ibizamini isabwa gutangwa n'ikigo cyujuje ibyangombwa. Kurugero,DINSEN yemejwe na CASTCO.
Ibipimo bya EN877: 2021 birasobanutse kandi birakomeye mugupima kuruta ibipimo bya EN877: 2006, byerekana iterambere ryikoranabuhanga rigezweho hamwe nibisabwa ku isoko mu nganda zikora ibyuma. Ishyirwa mu bikorwa ry’ibipimo bishya bizafasha kuzamura ireme ry’ibicuruzwa biva mu cyuma no guteza imbere umutekano n’ubwizerwe bwa sisitemu yo gufata amazi.
