If the plug of a lighting chain incorporates a means for disconnecting one end of the chain to facilitate installation, the connector fitted at the end of the cable shall have an entry such that the diameter of the opening and the distance from the front to live parts are equal to the corresponding dimensions specified in Figure 1. The two parts of the connector shall not separate when subjected to a pull force of 10 N.
Compliance shall be checked by means of a flat probe, 0,5 mm thick and 8 mm wide, with a rounded tip having a radius of 4 mm. It shall not be possible to touch live parts with this probe,when it is applied in any position with a force not exceeding 0,5 N, the chain being fitted with the lamps with which it is delivered.
Lampholder contacts in push-in lampholders shall be reliably secured in the lampholder body by means other than friction to avoid a displacement of the lampholder contacts such that live parts of the chain become accessible either through the bottom or top of the lampholder.
NOTE An example of an adequate securing method is by the provision of ears on the contacts of the lampholder.Compliance is checked by inspection and by the following test.
Six lampholders are heated for 7 h according to the requirements of Clause 12.3 of Section 12 of IEC 60598-1 in an orientation to reach the highest temperature. After the lampholders have cooled down to room temperature, the lamps are removed and a force of 15 N is applied for 1 min to each of the conductors connected. Following this, a force of 30 N is applied for 1 min to the two conductors together. The forces are applied at a distance of 3 mm±0,8 mm from the insertion points in the lampholder so as to try to move the contacts from the lampholders.AS NZS 60598.2.20 pdf free download.
