Marking test

The objective of the marking test is to check that the device is identified with a set of permanent, printed or embossed characters that denote the main descriptive features for assembly, installation and operation under conditions of safety.

The main features that are verified in electrical products are as follows:

  • Commercial reference name
  • Dimensions
  • Extended standard
  • Rated voltage
  • Rated current
  • Nature of the current

Test methods

The methodology usually consists of a visual inspection of these items, although additionally indelibility and durability tests of the marking may be performed by rubbing them with a water and hydrocarbon solution over a set period of time.

This must be performed using an automated special implement on some products.
