1.E27 Cap Gauge

1.1 Go Gauge (IEC 7006-27B-1)

Reference	Dimension（mm）	Tolerance（mm）	Limit after wear （mm）
d	26.45	+0.03/-0	26.50
d1	24.26	+0.03/-0	24.31
L	16.5	±0.1
O	28	±0.2
P	3.629	-
r	1.025	-
T	22.0	+0.0/-0.03
V	15	±0.1
W	5	±0.1

The shape part of the edge of the thread shall be broken with radius of 0.2mm to 0.3mm.

Purpose：

To check the maximum dimensions of the screw thread and dimension T1 minimum of caps on finished lamps.

Testing ：

When the cap on a finished lamp has been screwed into the gauge as far as it will go, the center contact shall be co-planar with, or project beyond, surface X

1.2 Not Go Gauge (IEC 7006-28A-1)

Reference	Dimension（mm）	Tolerance（mm）
d	26.05	+0.0/-0.01
L	16.5	±0.1
U	1	+0.0/-0.1
V	17.0	+0.05/-0
W	2	±0.1
α	Nom. 45°
Weight	0.15kg	±10%

Purpose：

To check the minimum outside (major) diameter of the screw thread.

Testing ：

When the gauge is placed over the thread of the cap on a finished lamp, held cap uppermost, the center contact shall not project beyond surface “X”. Only the weight of the gauge itself shall be used in the test.

1.3 Go for S1 dimension gauge (IEC 7006-27C-1)

Reference	Dimension（mm）	Tolerance（mm）
d	26.45	+0.03/-0.0
H	14	±0.1
M	13	±0.1
O	23.0	±0.03
S	8.5	+0.01/-0.0
V	1.5	+0.02/-0.0

Purpose：

To check the dimensions S1 minimum and S1 maximum of E27 caps on finished lamps.

Testing ：

When the cap on a finished lamp has been pushed into the gauge as far as it will go, the plunger surface “W” shall be co-planar with or project beyond surface “X” but it shall not project beyond surface “Y”.

1.4 Contact-making (IEC 7006-50-1)

The gauge is shown in the test position. In the rest position the plunger shall be above plane V.
