The Piston (Figure 8.1, Item 3) extends downward and exerts a force on
the test specimen until it breaks. The maximum breaking force required
relates to the splitting strength in N/cm
2
and is shown on the display.
5. After completion of the measurement, remove the Pedestal and
Sand Chute and clean off any sand deposits.
6.2.5 Twin-Transverse Shear Strength Measurement (PQS/M)
Prepare a test specimen as specified in Section 6.2.1.
1. Remove the Compression Insert (Figure 8.1, Item 4) (if
applicable) from the Piston (Figure 8.1, Item 3) (see Figure
6.2.4), and align the two pins of the Twin-Transverse Shear
Attachment Shear Unit (Figure 8.1, Item 11) in its place (see
Figure 6.2.5).
2. Align the Twin-Transverse Shear Attachment Base on the
Minilab Base Plate (Figure 8.1, Item 9), ensuring that attachment
cylinder pins are mounted in the corresponding holes on the
machine base (see Figure 6.2.6).
