1 Scope
This Technical report covers the testing and classification of luminaires according to IEC 62262. The application of an IK rating to a luminaire is considered to be a performance issue and is not directly related to the safety provisions of IEC 60598 standards covering luminaire safety.

3 Conditions of testing
3.1 In general, testing is conducted in accordance with IEC 62262, having regard to the general test conditions specified by IEC 60598-1 , Subclause 4.1 3, and the following conditions which are specific for the IK testing and rating of luminaires.
3.2 Impacts should not be applied through openings in the luminaire enclosure with an area less than 64 cm².
NOTE For example, no impact should be applied through the individual openings in optical controls (louvers) if their size is less than 64 cm².
3.3 Luminaires should be tested fully assembled and installed for use.
Luminaires for ceiling or wall mounting should be mounted on a rigid wooden board.
Suspended luminaires should be tested as in normal use, with the minimum suspension length detailed by the manufacturer’s instructions.
Luminaires to be installed on a pole, with or without a mast arm, should be installed on a rigid portion of the pole.
Floor mounted luminaires should be tested in a suitable rigid structure to simulate normal use.
3.4 Luminaires should not to be energised during test and no preconditioning of the luminaire sample is required.
3.5 Testing should be conducted on a single luminaire sample unless the results of impact testing of other areas of the luminaire could influence assessment of the result. Three impact blows should be applied to the point(s) of the luminaire considered to be the weakest.
3.6 Impact testing should be conducted using striking elements with head radius and material type as specified by IEC 60068-2-75. Spring hammer apparatus should be used for ratings up to and including IK06. For ratings IK07 and above, the use of pendulum or vertical hammer apparatus is acceptable, as most appropriate for the luminaire design and its intended installation.
3.7 Impact testing should be conducted with the luminaire in its intended mounting orientation whenever this is possible, and when this could affect the outcome of the test (e.g. for assessment of mounting surface fixing security). When impact testing of a ceiling-mounted luminaire is required from below the luminaire, and this is impractical, the luminaire may be rotated 90º (to a wall mounted position) for the purposes of this testing.
3.8 In cases where it may be impossible to carry out the impact test due to the luminaire construction, it is acceptable to use a specially-prepared luminaire to perform the test. For this situation, the modification should not impair the mechanical strength characteristics of the luminaire.
