The Administrator will make a determination as to the validity of manufacturer-furnished test data on the basis of:
    
    
        
        (a) 
         The correlation between the test procedures used by the manufacturer or testing agent and the procedures prescribed in subpart D;
     
    
        
        (b) 
         The choice of test vehicle(s) as representative of the manufacturer's claim for operation and/or principles of operation;
     
    
        
        (c) 
         The degree of control exercised over ambient and operating conditions in the tests, including vehicle calibrations;
     
    
        
        (d) 
         Accuracy and precision of the measurement techniques and instrumentation used in the tests;
     
    
        
        (e) 
         Disclosure of all test data acquired on the device, whether representing positive, negative, or inconclusive results;
     
    
        
        (f) 
         Qualifications and independence of the testing agent; and
     
    
        
        (g) 
         The extent to which test data include evaluation of the durability of the device, or its effect on vehicle durability.
