The image following/opposite shows a typical lot number format for Nye Lubricants products. An explanation of the format:
- AG – initials of the production technician that manufactured this particular lot or batch.
- 20 – year of manufacture, in this example 2020.
- 09 – month of manufacture, this example the 9th month/September.
- 22 – day of the month when the lot was manufactured, in this case the 22th of the month.
So the example lot number/batch number of the grease shown was manufactured by a production technician with the initials AG on 22 September 2020.
