Uvumilivu wa urefu: uvumilivu wa urefu kwa vipimo vyote ni upeo +5/-0 mm.
Utulivu: max.4% (utaratibu wa kupima kwa misingi ya ASTM B760)
Uzito: unene＜10.00mm wiani＞19.2g/cm³
unene (10.00-20.00mm) wiani = 19.1g/cm³
Ugumu wa Vickers:
≤0.10 mm ≥550 HV
0.10-0.05 mm ≥500 HV
0.50-1.50mm ≥470 HV
1.50-10.00mm ≥450 HV
10.00-20.00mm ≥420 HV
Kuonekana: Nyenzo zitakuwa za ubora wa sare, zisizo na mambo ya kigeni, mgawanyiko na fractures.
Karatasi ya kitanda (haijapunguzwa) inaweza kuwa na nyufa ndogo za makali.
Ubora wa uso:
Baridi iliyovingirwa ≤ 0.30mm kung'aa
Baridi iliyovingirwa 0.3-0.5 mm iliyochujwa
Moto umevingirwa ≥0.50 mm iliyochujwa
