Displays/overrides the Occasional load factor defined in the configuration. The default value changes according to the piping code and the frequency of occurrence.
ISO-14692
Occasional load factors are defined differently for different load cases (Operating, Sustained, Occasional, and Hydrotest). The default occasional load factors for these load cases are:
-
1.0
Sustained load cases
-
1.25
Operating load cases
-
1.33
Occasional and Hydrotest cases
The Occasional load factor and the System design factor from the Allowable Stress dialog box are multiplied together to generate the Part Factor for Loading (f2) as defined in ISO-14692. As an example, using a default system design factor of 0.67 with the above default occasional load factors results in the following default values for the part factor for loading:
Load Case |
System Design Factor |
Occasional Load Factor |
Part Factor for Loading |
Sustained (SUS) |
0.67 |
1.00 |
0.67 |
Operating (OPE) |
0.67 |
1.24 |
0.83 |
Occasional (OCC) |
0.67 |
1.33 |
0.89 |
Hydrotest (HYD) |
0.67 |
1.33 |
0.89 |
