IEC60061-3: 7006-25A-2 E27 Go Gauge for Lampholders
The drawings are intended only to illustrate the essential
dimensions of the gauge.
(1) Dimension S1 applies when the plunger is fully extended.
(2) Dimension D2 is the outside diameter at the open end of the
sleeve.
(3) When the plunger is fully retracted, marks A and Y shall
coincide and the end of the plunger shall be co-planar with the end
of the gauge.
See dimensions b1 and b2.
PURPOSE: To check:
a) The minimum dimensions of the lampholder screw thread according
to sheets 7004-21 and 7004-27.
b) Dimension X according to sheet 7005-20.
c) The mechanical compatibility of the lampholder with respect to
lamps having adverse dimensions.
TESTING: It shall be possible to screw the threaded part of the gauge into
the lampholder without using undue force (for the torque to be
applied see Publication 238, Sub-clause 4.4).
When the gauge has been screwed in as far as it will go, mark Y on
the plunger shall be co-planar with mark A on the shaft.
The sleeve is then placed over the shaft of the gauge with its open
end resting on the top edge of the screw shell of the holder. With
the sleeve in this position, the plunger is pushed down as far as
it will go.
Surface B of the gauge shall then lie between the marks X1 nad X2
on the plunger or be co-planar with either of them; it shall not
lie beyond them.
