USEFUL DATA 



Storage. The cement shall be stored in such a manner as to permit easy access 

 for proper inspection and identification of each shipment, and in a suitable weather- 

 tight building which will protect the cement from dampness. 



IV. INSPECTION 

 Inspection. Every facility shall be provided the purchaser for careful sampling 

 and inspection at either the mill or at the site of the work, as may be specified by the 

 purchaser. At least 10 days from the time of sampling shall be allowed for the com- 

 pletion of the 7-day test, and at least 31 days shall be allowed for the completion of 

 the 28-day test. The cement shall be tested in accordance with the methods herein- 

 after prescribed. The 28-day test shall be waived only when specifically so ordered. 



V. REJECTION 



Rejection. The cement may be rejected if it fails to meet any of the requirements 

 of these specifications. 



Cement shall not be rejected on account of failure to meet the fineness requirement 

 if upon retest after drying at 100 degrees C. for one hour it meets this requirement. 



Cement failing to meet the test for soundness in steam may be accepted if it passes 

 a retest using a new sample at any time within 28 days thereafter. 



Packages varying more than 5 per cent from the specified weight may be rejected; 

 and if the average weight of packages in any shipment, as shown by weighing 50 

 packages taken at random, is less than that specified, the entire shipment may be 

 rejected.
