Field of application

1) The test methods may be used for a specific silo design where the stored material is not listed in Table 7.1 or as an alternative to the simplified values given in Table 7.1. Reference stresses in the tests are either vertical or horizontal and they shall be representative of the stored material stresses after filling at the silo transition.

2) The test methods may also be used for the preparation of general values of material properties. Tests to determine general values shall be carried out, where applicable, at the following reference stress levels:

100 kPa to represent the vertical silo pressure (B8, B9 and B10)

50 kPa to represent the horizontal silo pressure (B7.2)

0 0
