  • Pedestal
    Adopting the new range of pedestals it is possible to test specimens with different diameters into the same triaxial cell.
    The  codes are self-explanatory:

    28 – WF4xxx/YY

    xxx = refers to specimen dia.
    031 = 38mm
    051 = 50mm
    071 = 70mm
    101 = 100mm
    151 = 150mm
     
    YY = refers to triaxial cell
    5 = 50mm
    7 = 70mm
    10 = 100mm
    15 = 150mm

    38 mm	28-WF4031/5	28-WF4031/7	28-WF4031/10	28-WF4031/15
    50 mm	28-WF4051/5	28-WF4051/7	28-WF4051/10	28-WF4051/15

    Top cap / Vacuum top cap
    New top caps differ only with respect to the diameter of the specimen, they are independent on the triaxialcell in use.

    28 – WFxxx/YY

    xxx = refers to specimen dia.
    032 = 38mm
    052 = 50mm
    072 = 70mm
    102 = 100mm
    152 = 150mm
     
    YY = refers the presence or not of the vacuum connector
    AV = YES vacuum connector
