How to use
- Always refer to the currently valid edition. Numbers here omit the year; state the edition year in purchase and acceptance documents.
- JJG are verification regulations used for annual metrology inspection; GB/T are test-method or product standards used for acceptance and test reports.
- Export projects often require ISO 6507/6508 together with ASTM E18/E384; matching calibration certificates ship with the machine.
