Table 3 – Sampling

6.5 Determination of test results

6.5.1 If the inspection results of chemical composition are unqualified, the batch of products shall be deemed unqualified.

6.5.2 If the test result of the transmittance of infrared absorption of impurities in the range of 4 000 cm-1 ~ 1 000 cm-1 is unqualified, double the number of samples shall be taken for repeated testing. If the repeated test results are still unsatisfactory, the batch of products shall be deemed unqualified.

6.5.3 If the inspection result of the appearance quality is unqualified, the batch of products shall be deemed unqualified.
