Your micrometer will come with a manufacturer's declaration that the above mentioned specifications have been met using traceable national standards. No other form of certification is included.
The manufacturer's warranty is 12 months from the date of shipment, covering parts and labor for any manufacturing defects. Original documentation is required in case of warranty claims.
A word of warning: do not modify the micrometer body in any way. Don't grind it so that it'll fit into a tight space. Any tampering with the body will surely ruin the accuracy forever.

The manufacturer writes,
"Every micrometer is supplied ready for use and inspected. However, since they might get out of adjustment during transportation, we [Etalon] advise to check the zero-setting before use. We also firmly advise our customers not to dismantle the instruments needlessly. They need only be cleaned using pure benzene (see note) and periodically lubricated with a few drops of high quality purified oil. Check the zero-setting as often as necessary. The guarantee does not cover new measuring instruments dismantled by customers."
Please note, the use of some solvents will destroy the plastic red and blue markers as well as the plastic cover.
