    Gofyniad Prawf

    Prawf 1.hardness
    Pan fydd angen terfynau caledwch, ymgynghorir â'r gwneuthurwr. Rhestrir caledwch nodweddiadol yn y tabl. Pan nodir, bydd y prawf caledwch yn cael ei berfformio ar 1 % o'r tiwbiau.

    Profion 2.Tension
    Pan fydd angen eiddo tynnol, ymgynghorir â'r gwneuthurwr. Rhestrir priodweddau tynnol nodweddiadol ar gyfer rhai o'r graddau mwy cyffredin ac amodau thermol yn y tabl.

    Profion 3.Nondestructive
    Mae gwahanol fathau o brofion ultrasonic neu electromagnetig nondestructive ar gael. Bydd y prawf i'w ddefnyddio a therfynau arolygu yn cael eu sefydlu gan y gwneuthurwr a chytundeb prynwr.

    Prawf 4.flaring
    Pan fydd gofynion arbennig ar gyfer glendid dur, bydd y dulliau prawf a therfynau derbyn yn cael eu sefydlu gan y gwneuthurwr a chytundeb prynwr.
