[II. PACKAGES, MARKING AND STORAGE. 
9. The cement shall ho delivered in suitable bags or barrels with 
the brand and name of the manufacturer plainly marked thereon, 
unless shipped in bulk. A bag shall contain 94 pounds net. A 
barrel shall contain 870 pounds net. 
10. The cemenl shall be stored in such a manner as to permit 
easy access for proper Inspection and Identification of each ship- 
ment, and in a suitable weather-tight building which will protect 
the cement from dampness. 
IV. INSPECTION. 
11. Every facility shall he provided the purchaser for careful 
sampling and inspection at either the mill or at the site of the 
work, as may he specified by the purchaser. At least 10 days 
from the time of sampling shall be allowed for the completion 
Of the 7-day test, and at least 81 days shall he allowed for the 
completion of the 28-day test. The cement shall be tested in ac- 
cordance wiih the methods hereinafter prescribed. The 28-day 
test shall be waived only when specifically so ordered. 
V. REJECTION. 
12. (a) The cement may he rejected if it fails to meet any of 
the requirements of these specifications. 
(6) Samples of each lot shall he required to show practically 
uniform results in tests. Marked deviation from the uniform re- 
sult may he considered cause for rejection, even though the test 
requirements may he otherwise fulfilled. 
18. Cement shall not be rejected on account of failure to meet 
the fineness requirement if upon retest after drying at 100° C. 
lor one hour it meets this requirement. 
14. In all cases the user, purchaser, or engineer in control 
of any construction where Portland cement is used reserves the 
option to take check samples for the purpose of making tests to 
determine the stability of the product and such check tests will 
be the basis for acceptance or rejection regardless of previous 
decisions. 
l;"i. Packages varying more than 5 per cent from the specified 
weight may he rejected ; and if the average weight of packages 
in any shipment, as shown by weighing 50 packages taken at ran- 
dom, is less than that specified, the entire shipment may he re- 
jected. 
TESTS. 
VI. SAMPLING. 
Sampling. 10. Tests may he made on individual or composite samples as 
may be ordered. Each test sample should weigh at least 8 pounds. 
17. (a) Individual sample. — If sampled in cars, one test sample 
shall be taken from each 50 barrels or fraction thereof. If sam- 
pled in bins, one sample shall he taken from each 100 barrels. 
(b) Composite sample. — If sampled in cars, one sample shall 
be taken from 1 sack in each 40 sacks (or 1 barrel in each 10 
barrels) and combined to form one test sample. If sampled in 
bins or warehouses, one test sample shall represent not more 
than 200 barrels. 
18. Cemenl may be sampled at the mill by any of the follow- 
ing methods that may he practicable, as ordered: 
en From the conveyor delivering to the hi):. — At least 8 
pounds of cement shall be taken from approximately each 100 
barrels passing over the conveyor. 
(h) From (Mat bins hi/ means of proper sampling tabes. — 
Tubes inserted vertically may be used for sampling cement to a 
maximum depth of 10 feet. Tubes inserted horizontally may be
