76 Example II Incompliances to item 10.6 of standard HRN EN and section 4 standard HRN EN (Design): Portable luminaries for children shall have adequate stability Compliance shall be checked by placing the luminarie in the most unfavourable position of normal use, on a plane inclined at an angle of 15 ' to the horisontal, the surface of the olane being such that the luminarie dose not slide. The luminarie shall not overturn Flexible neck of luminarie is possible to set to position of difference angle 180 ° between diferent parts . On picture 5 5 is iluminant with neck bend to final position to the base. In that position luminarie is overturned at angle of 6 °.

77 Example II Sl. 6 Sl. 7 3.4 - HRN EN 60598-1: Test of marking
Compliance with the requirements of 3.2 and 3.3 is checked by inspection and by the following test: The durability of the marking is checked by trying to remove it by rubbing lightly for 15 s with a piece of cloth soaked with water and, after drying, for a further 15 s with a piece of cloth soaked with petroleum spirit and by inspection after the tests detailed in Section 12 have been completed. After the test, the marking shall be legible, marking labels shall not be easily removable and they shall show no curling.
