A regular double sampling plan shall be used, with the first sample of three tubes with an acceptance number of zero, and a

9、second sample of three tubes with a combined acceptance number of zero. In the event of failure, the test will be made as a part of conformance inspection, part 2, code level D, with an acceptance level of 6.5. The regular “12-calendar month“ double sampling plan shall be reinstated after three cons
