What is the maximum tapping profile to be used to test water heaters < 400kW having a rated capacity exceeding tapping profile 4XL?

The water heater is in the scope of Regulation (EU) 814/2013 and in consequence needs to meet the minimum requirements set. The water heater is to be tested with the highest declared tapping profile (e.g. 4XL).
