next heavier grade, the brick shall be classified in the heavier grade when the 
fractional part of the weight is 0.5 pound or more. 
RECORD 
20. A complete and continuous record shall be kept of the operation of all 
rattleis working under these tentative methods of testing. This record shall 
contain the following data concerning each test made : 
1. The name of the person, firm, or corporation furnishing each sample 
tested. 
2. The name of the maker of the brick represented in each sample tested. 
3. The name of the street or contract, which the sample represented. 
4. The brands or marks upon the bricks by which they were identified. 
5. The number of bricks furnished. 
6. The date on which they were received for test. 
7. The date on which they were tested. 
8. The drying treatment given before testing, if any. 
9. The length, width, and thickness of the bricks. 
10. The collective weight of the ten large spherical shot used in making the 
te-r at the time of their last standardization. 
11. The number and collective weight, of the small spherical shot used in 
making the test at the time of their last standardization. 
12. The total weight of the shot charge, after its last standardization. 
13. Certificate of the operator that he examined the condition of the machine 
as to staves, liners, and any other parts affecting the barrel, and found them to 
conform to the requirements at the beginning of the test. 
14. Certificate of the operator of the number of charges tested since the last 
standardization of shot charge and last renewals of stave liners. 
15. The time of the beginning and ending of each test, and the number of 
revolutions made by the barrel during the test, as shown by the counting 
machine. 
16. Certificate of the operator as to number of stops and starts made in 
each test. 
17. The initial collective weight of the 10 bricks composing the charge and 
their collective weight after rattling. 
18. The loss calculated as a percentage of the initial weight and the calcula- 
tion itself, the correction factor, and the corrected percentage of loss. 
19. The number of broken bricks and remarks upon the portions which were 
included in the final weighing. 
20. General remarks upon the test and any irregularities occurring in its 
execution. 
21. The certificate of the operator that the test was made in accordance with 
the requirements of the American Society for Testing Materials and that the 
record is a true record. 
22. The signature of the operator or person responsible for the test. 
23. The location of the laboratory where the test was made and name of 
the owner. 
24. The serial number of the test. 
In the event of more than one copy of the record of any test being required, 
they may be furnished on separate sheets and marked duplicate, but the original 
record shall always be preserved intact and complete. 28
