A、 Because the inflation tests and material inspections can identify and condemn rafts which have more than minor installation defects, rafts which pass the tests and inspections may be in service for a period time with no fixed limit.
B、 As the inflation tests and material inspections can affirm and declare the minor installation defects of the rafts, rafts checked by tests and inspections may come into service with no definition.
C、 Rafts succeed in tests and inspections may keep the service indefinitely from a time that the inflation tests and material inspections identified and announced the rafts with many minor installation defects.
