Kusiyana Pakati pa EN877:2021 ndi EN877:2006

Muyezo wa EN877 umatchula zofunikira pakugwira ntchito kwakuponya mapaipi achitsulo, zopangirandizolumikizira zawoamagwiritsidwa ntchito m'makina a mphamvu yokoka m'nyumba.EN877:2021ndiye mtundu waposachedwa wa muyezo, m'malo mwa EN877:2006 wakale. Kusiyana kwakukulu pakati pa matembenuzidwe awiriwa poyesa kuyesa ndi motere:

1. Kuyesa kuchuluka:

TS EN 877: 2006 Imayesa makamaka mawonekedwe amakina ndi kusindikiza kwa mapaipi ndi zomangira.

TS EN 877: 2021: Pamaziko a mayeso oyambilira, zida zowonjezera zoyeserera pakuwongolera mawu, kukana kwa dzimbiri, kukana moto ndi zina zamapaipi.

2. Njira zoyesera:

TS EN 877: 2021 imasintha njira zina zoyesera kuti zikhale zasayansi komanso zololera, monga:Kuyesa kwa Chemical corrosion resistance: Mayankho atsopano ndi njira zoyesera zimagwiritsidwa ntchito, monga kugwiritsa ntchito pH2 sulfuric acid solution m'malo mwa yankho la hydrochloric acid loyambirira, ndikuwonjezera kuyesa kukana dzimbiri kwamankhwala ambiri.

Kuyesa kwa ma Acoustic performance: Zofunikira zoyeserera pakuwongolera kwamapaipi, monga kugwiritsa ntchito njira yapaipi yapaipi kuti muyeze kutsekereza kwamapaipi.

Mayeso a momwe moto umagwirira ntchito: Zofunikira zoyeserera pakuyesa kukana moto kwa mapaipi, monga kugwiritsa ntchito njira yoletsa kukana moto kuyesa kukhulupirika kwa mapaipi pansi pamoto.EN 877: 2021 imagwiritsa ntchito utoto wokhala ndi giredi A1 yokana moto

3. Zofunikira pakuyesa:

TS EN 877: 2021 yawonjezera zofunikira zoyesa pazowonetsa zina, monga:Mphamvu yolimba: idakwera kuchokera 150 MPa mpaka 200 MPa.
Elongation: kuchuluka kuchokera 1% mpaka 2%.

Chemical kukana dzimbiri: Zofunika kukana dzimbiri pa zinthu zambiri zamankhwala, monga zofunika kukana dzimbiri pazinthu zamchere monga sodium hydroxide ndi potaziyamu hydroxide.

4. Lipoti la mayeso:

TS EN 877: 2021 ili ndi zofunikira zokhwima pazomwe zili ndi mtundu wa lipoti la mayeso, monga:Imafunika lipoti la mayeso kuti liphatikizepo zambiri monga njira zoyesera, mikhalidwe yoyeserera, zotsatira zake, ndi zomaliza.

Lipoti la mayeso likufunika kuti liperekedwe ndi bungwe loyezetsa anthu oyenerera. Mwachitsanzo,DINSEN imatsimikiziridwa ndi CASTCO.
Muyezo wa EN877:2021 ndiwokwanira komanso wokhwima pakuyesa kuposa muyezo wa EN877:2006, wowonetsa zaukadaulo waposachedwa komanso zofuna za msika pamakampani opanga zitoliro zachitsulo. Kukhazikitsidwa kwa mulingo watsopanowu kudzathandizira kukonza bwino kwa zida zapaipi yachitsulo komanso kulimbikitsa chitetezo ndi kudalirika kwa njira zoyendetsera ngalande.
