II-PEDisitifiketi kanyeCPRisitifiketi samapayipi ensimbi angenamthungo sigunyazwe amazinga nezidingo ezahlukene:

1.Isitifiketi se-PED (Isisetshenziswa Sezisetshenziswa Zokucindezela):
Umehluko: Isitifiketi se-PED siwumthetho waseYurophu osebenza emikhiqizweni efana neimishini yokucindezelanamapayipi ensimbi angenamthungo. Iqinisekisa ukuthi lezi zisetshenziswa zihlangabezana nezindinganiso zokuphepha nokusebenza emakethe yaseYurophu.
Isimo: Isitifiketi se-PED sisebenza kumishini yokucindezela kanye namasistimu amapayipi akhiqizwayo, athengiswe noma angeniswa emakethe yaseYurophu. Iqinisekisa ukuthi umkhiqizo uhlangabezana nezidingo zomthetho ngaphakathi kwe-European Economic Area.
2.Isitifiketi se-CPR (Umthetho Wemikhiqizo Yokwakha):
Umehluko: Isitifiketi se-CPR ngomunye umthethonqubo waseYurophu osebenza kuwoimikhiqizo yokwakha, okuhlanganisa izinto ezithile nezingxenye ezisetshenziswa ekwakheni.
Isimo: Ngamapayipi ensimbi angenamthungo, uma lawa mapayipi esetshenziswa ezakhiweni zokwakha noma izinhlelo zokusebenza ezihlobene nokuphepha kwezakhiwo, kungase kudingeke ukuthi ahambisane nezidingo ze-CPR. Isitifiketi se-CPR siqinisekisa ukusebenza kokuphepha komkhiqizo endaweni yokwakha.
Kafushane, isitifiketi se-PED sisebenza kumishini yokucindezela namasistimu amapayipi ahlobene, kuyilapho isitifiketi se-CPR sisebenza ezintweni zokwakha nezingxenye, okuhlanganisa namapayipi ensimbi angenamthungo ukuze asetshenziswe okuthile. Zombili izitifiketi ziqinisekisa ukuthi umkhiqizo uthobelana nezidingo ezifanele zomthetho nokuphepha emakethe yaseYurophu.

Isitifiketi se-PED (Isisetshenziswa Sezisetshenziswa Zokucindezela)
Amazinga asebenza ezitifiketini ze-PED nezitifiketi ze-CPR ahlukile.

Izitifiketi ze-PED ziyasebenza kumishini yokucindezela kanye namasistimu amapayipi ahlobene. Izindinganiso zayo ngokuvamile zihlanganisa kodwa azikhawulelwe kulokhu okulandelayo:

Amazinga ochungechunge we-EN 10216 afana ne-EN10216-1 P235TR1; I-EN10216-2 P235GH; I-EN10216-3 P275NL1;

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

I-EN10210 S235JRH; I-EN10210 S355JOH; I-EN10210 S355J2H
- Lawa mazinga amboza amapayipi ensimbi angenamthungo ekufakweni kwengcindezi.

Isitifiketi se-CPR (Umthetho Wemikhiqizo Yokwakha)
Isitifiketi se-CPR sisebenza ezintweni zokwakha nezingxenye. Izindinganiso zayo ikakhulukazi zihlanganisa kodwa azikhawulelwe kulokhu okulandelayo:

EN 10219 amazinga ochungechunge EN10219 S235JRH;EN10219 S275J2H;EN10219 S275JOH;EN10219 S355JOH;EN10219 S355J2H, EN10219 S355K2H;

- Lawa mazinga amboza izimfuneko zamashubhu angewona ama-alloy kanye nama-fine-grained ngezinjongo zesakhiwo.

EN 10210 amazinga ochungechunge - EN10210 S235JRH;I-EN10210 S355JOH;EN10210 S355J2H, lawa mazinga amboza izimfuneko zamashubhu ensimbi esakhiwe esakhiwe esishisayo.

I-TS EN 10025 Amazinga ochungechunge - Lawa mazinga amboza izimo zobuchwepheshe zokulethwa kwensimbi yesakhiwo esingenawo alloy esishisayo.I-EN 10255 uchungechunge lwamazinga

- Lawa mazinga ahlanganisa izidingo zezinsimbi ezingezona i-alloy kanye ne-alloy zamapayipi ensimbi angenamthungo nashiselwe amanzi nolunye uketshezi.

Kafushane, isitifiketi se-PED sisebenza kumishini yokucindezela kanye nezinhlelo zamapayipi ahlobene, kuyilapho isitifiketi se-CPR sisebenza ezintweni zokwakha nezingxenye, okuhlanganisa namapayipi ensimbi angenamthungo ezinhlelo zokusebenza ezithile. Zombili izitifiketi zenzelwe ukuqinisekisa ukuthi imikhiqizo ihlangabezana nezidingo ezifanele zomthetho nezokuphepha emakethe yaseYurophu.
