40、ent of dyestuff for finish or color shall not be regarded as objectionable. 4.2.3 Length examination. 4.2.3.1 Individual rolls. During the yard-by-yard examination, each roll in the sample shall be examined for length. Any roll found to be less than the minimum specified or more than 2 yards less th

41、an the length marked on the ticket shall be considered a defect with respect to length. The lot shall be unacceptable if two or more rolls in the sample are defective in respect to length. 4.2.3.2 Total yardage in sample. The lot shall be unacceptable if the total of the actual lengths of rolls in t

42、he sample is less than the total of the lengths marked on the tickets. 4.2.4 End item testing. The cloth shall be tested for the characteristics listed in TABLE II. The methods for testing specified in TABLE II shall be followed. The physical and chemical values specified in Section 3 apply to the a

43、verage of the determinations made on a sample unit for test purposes as specified in the applicable test methods. The sample unit shall be 5 continuous yards of full width finished cloth. The lot shall be unacceptable if one or more sample units fail to meet any test requirement specified. All test

44、reports shall contain the individual values utilized in expressing the final results. Unless otherwise specified, testing shall be performed under standard conditions in accordance with ASTM D 1776.
