9、me rolls orbolts of fabric may vary considerably when using each of thethree options listed herein.For this reason,the same pointassignment option should be used in cases of disagreementarising from differences of values reported by the purchaserand the supplier.5.3 If there are differences of pract
10、ical significance betweenreported test results for two laboratories(or more),compara-tive test should be performed to determine if there is astatistical bias between them,using competent statistical assis-tance.As a minimum,ensure the test samples to be used are ashomogeneous as possible,are drawn f

12、If a bias is found,either its causemust be found and corrected,or future test results for thatmaterial must be adjusted in consideration of the known bias.6.Apparatus6.1 A suitable fabric inspection machine providing a flatviewing area and an interruptible speed controlled fabric1These test methods
