ISRM Part II:1985:6 | Suggested Method for Determining Point Load Strength |
Input
Lab-Rock | Point Load
To calculate the Is(50), you must first select the standard from the Test_Method field on the Point_Load table that the specimen is being tested against.
Enter the test data in the data entry fields in the lower table and click Save, Ctrl+S or change table to initiate the calculation. The values will be calculated automatically and the result will be displayed in the calculated fields.
After a record is entered for the first time and saved, the first row will automatically copy down for fields where it might be useful.
The field Number_to_Exclude_from_Is50_Mean on Point_Load_Test (upper) table defines the number of highest and lowest values to exclude from point load strength test mean (eg. If Number_to_Exclude_from_Is50_Mean is 2, the two highest and the two lowest values will be excluded for the mean calculation). The excluded tests are shown in the Exclude_From_Mean check box.The net mean is written to the Point_Load_Test (upper) table.
Moisture contents for each specimen are recorded in the Moisture_Content table.
Output
- Graphic Text Report | L R POINT LOAD STRENGTH SAMP
- Histogram | A L R POINT LOAD INDEX
