Solvents should not be used to clean batteries and modules as otherwise damage to the plastic components can result. Approved cleaning fluids are only those that are expressly specified by the battery manufacturer.
6.2 Test procedure
6.2.1 General
The test shall be carried out on three of the required markings in their definitive size, form, material and execution.
The test shall consist of visual verification for the presence and legibility of all the required markings before and after exposure to selected chemicals.
The durability of the marking shall be tested in accordance with IEC 60896-21:2004, 6.6 and IEC 60896-22:2004, 6.6.
6.2.2 Test with water and recommended cleaning agents
The markings shall be rubbed for 15 s with a piece of cloth soaked with water and then rubbed for 15 s with a piece of cloth soaked with the cleaning agent recommended by the battery manufacturer for battery cleaning, dried in air and then inspected visually.
6.2.3 Test with electrolyte
The markings shall be rubbed for 15 s with a piece of cloth soaked with electrolyte, dried in air and then inspected visually.
6.2.4 Test with neutralizing solutions
The markings shall be rubbed for 15 s with a piece of cloth soaked with a saturated solution of sodium carbonate (Na2CO3) or sodium bicarbonate (NaHCO3) in water, dried in air, and then inspected visually.
6.3 Criteria
The marking symbols shall be readable and visible after each test.
