IEC60061-3: 7006-22A-5 E27 Gauge for Testing Contact-Making and Protection Against Accidental Contact During Insertion of Lamps in Lampholders
The drawing is intended only to illustrate the dimensions essential for interchangeability.The drawings are intended only to illustrate the essential dimensions of the gauge.The drawings are intended only to illustrate the essential dimensions of the gauge.
(1) Dimension E is the reference diameter associated with dimension S.
PURPOSE: To check E27 lampholders in respect of:
a) Contact-making with lamps having adverse dimensions.
b) Protection against accidental contact with live parts, viz. the cap shell, during insertion of a
TESTING: The holder is connected in the test circuit as shown.
a) With switch A in position 2 and switch B open, the gauge is screwed fully home.
In this position, both lamps shall light.
b) After the test of a) above, the gauge is withdrawn until the lamps are extinguished.
Switch A is moved to position 1 and switch B is closed. The gauge is then screwed in slowly until
either of the lamps lights. With the gauge held in this position, switch B is opened and the test
probe at the side of the gage is slid downwards as far as it will go into the space between the gauge
and the holder. In this position the lamps shall not light.
