    Kinakailangan sa Pagsusulit

    1. Hardness Test
    Kapag kinakailangan ang mga limitasyon sa katigasan, dapat kumonsulta sa tagagawa. Ang mga tipikal na katigasan ay nakalista sa Talahanayan . Kapag tinukoy, ang hardness test ay isasagawa sa 1 % ng mga tubo.

    2. Mga Pagsusuri sa Pag-igting
    Kapag kinakailangan ang mga katangian ng makunat, dapat kumonsulta sa tagagawa. Nakalista sa talahanayan ang mga tipikal na katangian ng tensile para sa ilan sa mga mas karaniwang grade at thermal condition.

    3.Hindi Mapanirang Pagsusulit
    Available ang iba't ibang uri ng nondestructive ultrasonic o electromagnetic test. Ang pagsubok na gagamitin at ang mga limitasyon sa inspeksyon ay dapat itatag ng kasunduan ng tagagawa at mamimili.

    4.Flaring Test
    Kapag may mga espesyal na kinakailangan para sa kalinisan ng bakal, ang mga pamamaraan ng pagsubok at mga limitasyon ng pagtanggap ay dapat itatag ng kasunduan ng tagagawa at mamimili.
