Mapaipi achitsulo opangidwa ndi makona anayi a DIN 17100 St52.3 anatumizidwa ku Australia.
DIN 17100 ndi muyezo womwe umagwiritsidwa ntchito pazigawo zachitsulo, mipiringidzo yachitsulo, ndodo za waya, ndi zinthu zosalalawopanda msokondi magawo opindika, ozungulira ndi ozungulira, zomangira, ndi zinthu zomalizidwa pang'ono m'zitsulo zonse zomwe zimapangidwa zomwe zimaperekedwa mu mkhalidwe wotentha kapena wokhazikika pambuyo popangidwa.
St52.3 ndi imodzi mwa magiredi, ndipo nambala yake ndi 1.0570.
Botop isanatumizidwe, imakonza kuti akatswiri odziwa bwino ntchito aziyang'ana mosamala zinthuzo kuti atsimikizire kuti khalidwe la chinthucho likukwaniritsa zofunikira za makasitomala.
Choyamba, khalidwe la pamwamba, m'lifupi, kutalika, kutalika, sikweya, ndi mawonekedwe ena a chitoliro chachitsulo chomangidwa zimawunikidwa mosamala kuti zitsimikizire kuti zikutsatira miyezo ndi zofunikira za makasitomala.
Kenako, mankhwala ndi makina a chitoliro chachitsulo chomangidwa amawunikidwa.
EN 17100 St52.3 ili ndi zofunikira zotsatirazi pakupanga mankhwala:

Kapangidwe ka mankhwala ka St52.3 kamayesedwa ndi spectrometer, ndipo zonse zomwe zili mu chinthuchi zimakwaniritsa zofunikira za makasitomala poyerekeza ndi zofunikira.
Kapangidwe ka makina ka EN 17100 St52.3 makamaka kamaphatikizapo mphamvu yokoka ndi mphamvu yotulutsa, zomwe zimayesedwa poyesa kukoka.

Pambuyo pomaliza kuwunika konse ndikuwonetsetsa kuti khalidwe likukwaniritsa zofunikira zonse, Chikalata Choyesera Zinthu (MTC) chimaperekedwa. Pambuyo pake, makonzedwe amapangidwa a kutumiza ndi ntchito zina zokhudzana nazo.
Kuyambira pomwe idakhazikitsidwa mu 2014, Botop Steel yakhala kampani yotsogola yogulitsa mapaipi achitsulo cha kaboni kumpoto kwa China, yodziwika bwino chifukwa cha ntchito zake zabwino kwambiri, zinthu zapamwamba, komanso mayankho omveka bwino.
Pa oda iliyonse, Botop nthawi zonse imatsatira njira yodalirika komanso mitengo yabwino, ndikusankha ife kuti tikupatseni zinthu zodalirika za chitoliro chachitsulo.
