1. A building panel or a set of such building panels, comprising:
a front surface and a back surface each extending between a first edge and an opposite second edge, and between a third edge and an opposite fourth edge, wherein the back surface is parallel and spaced apart to the front surface in a direction perpendicular to the front surface;
a first mechanical locking device arranged at the respective first edge and the opposite second edge for locking of similar or essentially identical building panels in directions parallel and perpendicular to the front surface in an assembled position;
a second mechanical locking device arranged at the respective third edge and the opposite fourth edge for locking of similar building panels or essentially identical building panels in directions parallel to the front surface in an assembled position,
wherein the first mechanical locking device comprises, at the second edge, a locking tongue configured to cooperate with a tongue groove of a first mechanical locking device of an adjacent building panel, arranged at the first edge of said adjacent building panel for locking said building panels in at least a direction perpendicular to the front surface in an assembled position,
wherein the second mechanical locking device comprises, at the third edge, a locking strip comprising a locking element configured to cooperate with a locking groove of a second mechanical locking device of an adjacent building panel, arranged at the fourth edge of said adjacent building panel for locking said building panels in at least a direction parallel to the front surface in an assembled position, wherein the locking element of the locking strip of the second mechanical locking device protrudes upward from an upper surface of the locking strip of the second mechanical locking device,
wherein said locking tongue of said first mechanical locking device comprises a lowermost surface configured to cooperate with an upper surface of a locking strip of the first mechanical locking device of the adjacent building panel, arranged at the first edge of said adjacent building panel, in an assembled position,
wherein, directly adjacent to said locking tongue, said second edge comprises a groove extending higher than the lowermost surface of said locking tongue and configured to receive an upwardly projecting locking element of the locking strip of the first mechanical locking device of the adjacent building panel, in the assembled position, and
wherein a plane extending parallel with the front surface and through the lowermost surface of the locking tongue of said first mechanical locking device extends through the locking strip of said second mechanical locking device below a lowermost upper point of the locking strip of the second mechanical locking device, the lowermost upper point being a lowermost point of the upper surface of the locking strip of the second mechanical locking device along an entire surface area of the locking strip of the second mechanical locking device.
