II-PEDisitifiketi kanyeI-CPRisitifiketi samapayipi ensimbi angenamthungo siqinisekiswe ngezindinganiso nezidingo ezahlukene:

1.Isitifiketi se-PED (Isiqondiso Semishini Yokucindezela):
Umehluko: Isitifiketi se-PED siwumthetho waseYurophu osebenza emikhiqizweni efanaimishini yokucindezelakanye namapayipi ensimbi angenamthungo. Kuqinisekisa ukuthi le mishini ihlangabezana nezindinganiso zokuphepha nokusebenza emakethe yaseYurophu.
Isimo: Isitifiketi se-PED sisebenza emishinini yokucindezela kanye nezinhlelo zamapayipi ezikhiqizwa, ezithengiswayo noma ezingeniswe emakethe yaseYurophu. Siqinisekisa ukuthi umkhiqizo uhlangabezana nezidingo zomthetho ngaphakathi kweNdawo Yezomnotho yaseYurophu.
2.Isitifiketi se-CPR (Umthethonqubo Wemikhiqizo Yokwakha):
Umehluko: Isitifiketi se-CPR singomunye umthetho waseYurophu osebenza ku-imikhiqizo yokwakha, okuhlanganisa ezinye izinto nezinto ezisetshenziswa ekwakheni.
Isimo: Kumapayipi ensimbi angenamthungo, uma lawa mapayipi esetshenziswa ezakhiweni zokwakha noma ezisetshenziswayo ezihlobene nokuphepha kwesakhiwo, kungadingeka ukuthi ahambisane nezidingo ze-CPR. Isitifiketi se-CPR siqinisekisa ukusebenza kokuphepha komkhiqizo ensimini yokwakha.
Ngamafuphi, isitifiketi se-PED sisebenza emishinini yokucindezela kanye nezinhlelo zamapayipi ahlobene, kanti isitifiketi se-CPR sisebenza ezintweni zokwakha kanye nezingxenye, okuhlanganisa namapayipi ensimbi angenamthungo okusetshenziswa okuthile. Zombili lezi zitifiketi ziqinisekisa ukuthi umkhiqizo uhambisana nezidingo zomthetho nezokuphepha ezifanele emakethe yaseYurophu.

Isitifiketi se-PED (Isiqondiso Semishini Yokucindezela)
Izindinganiso ezisebenza ezitifiketini ze-PED kanye nezitifiketi ze-CPR zihlukile.

Izitifiketi ze-PED ziyasebenza emishinini yokucindezela kanye nezinhlelo zamapayipi ezihlobene. Izindinganiso zayo zivame ukufaka okulandelayo kodwa azigcini lapho:

Izindinganiso zochungechunge lwe-EN 10216 ezifana ne-EN10216-1 P235TR1; EN10216-2 P235GH; EN10216-3 P275NL1;

Izindinganiso zochungechunge lwe-ASTM ezifanaI-ASTM A106 GrBASTM A106 GrC;I-ASTM A53 GrBASTM A333/A333M-18 Gr6;

EN10210 S235JRH; I-EN10210 S355JOH; I-EN10210 S355J2H
- Lezi zindinganiso zimboza amapayipi ensimbi angenamthungo okusetshenziswa kokucindezela.

Isitifiketi se-CPR (Umthethonqubo Wemikhiqizo Yokwakha)
Isitifiketi se-CPR sisebenza ezintweni zokwakha kanye nezingxenye. Izindinganiso zaso zifaka phakathi okulandelayo kodwa azikhawulelwe kukho:

Izindinganiso zochungechunge lwe-EN 10219 EN10219 S235JRH;EN10219 S275J2H;EN10219 S275JOH;EN10219 S355JOH;EN10219 S355J2H, EN10219 S355K2H;

- Lezi zindinganiso zimboza izidingo zamashubhu angewona a-alloy kanye nama-fine-grained ngezinhloso zesakhiwo.

EN 10210 amazinga ochungechunge - EN10210 S235JRH;EN10210 S355JOH;EN10210 S355J2H, lawa mazinga ahlanganisa izidingo zamashubhu ensimbi akhiwe ngokushisa.

Izindinganiso zochungechunge lwe-EN 10025 - Lezi zindinganiso zihlanganisa izimo zokulethwa kobuchwepheshe zensimbi yesakhiwo engaguquki eshisayo.Uchungechunge lwezindinganiso ze-EN 10255

- Lezi zindinganiso zihlanganisa izidingo zezinsimbi ezingezona eze-alloy neze-alloy zamapayipi ensimbi angenamthungo nashibilikisiwe amanzi nezinye izinto eziwuketshezi.

Ngamafuphi, isitifiketi se-PED sisebenza emishinini yokucindezela kanye nezinhlelo zamapayipi ahlobene, kanti isitifiketi se-CPR sisebenza ezintweni zokwakha kanye nezingxenye, okuhlanganisa namapayipi ensimbi angenamthungo ezicelo ezithile. Zombili izitifiketi zenzelwe ukuqinisekisa ukuthi imikhiqizo ihlangabezana nezidingo zomthetho nezokuphepha ezifanele emakethe yaseYurophu.
