1) E39 Go Gauge for Screw Thread of Lampholders 7006-24E-1

The drawings are intended only to illustrate the essential dimensions of the gauge.

For details of lampholder E39, see sheet 7005-24A.

PURPOSE: To check the minimum dimensions of the E39 lampholder screw thread and the maximum and minium values of dimension X. It is not intonded that this gauge be applied to lampholers with lamp-gripping features in the screw shell area.

TESTING: It shall be possible to screw the gauge into the lampholder without using undue force. When the gauge is screwed in as far as it will go, the rim of the screwed shell of the lampholder shall be co-planar with, or project beyond, surface Y1, but it shall not project beyond surface Y2.

2) E40 Go Gauges for Screw Threads of Lampholders 7006-25-7

The drawing is intended only to illustrate the essential dimensions of the gauge.

For details of screw thread of lampholders E10, E14 and E40, see sheets 7004-22, 7004-23 and 7004-24 respectively.

The sharp part of the edge of the threed at the underside of the gauge for checking lampholders E10 and E14 shall be broken with a radius of 0,5 + 0,05 mm.

The sharp part of the edge of the thread at the underside of the gauge for checking lampholders E40 shall be broken with a radius of 1,0 + 0,05 mm.

An additional allowance for wear of - 0,01 mm is permitted beyond the manufacturing tolerance indicated.

PURPOSE: To check the minimum dimensions of the lampholder screw thread and dimension X shown on sheet 7005-20.

TESTING: It shall be possible to screw the gauge into the lampholder without using undue force.
(For the torque to be applied in case of doubt, see IEC 238, subclause 4.4).
When the gauge has been screwed in as far as it will go, the rim of the screw shell of the lampholder shall be co-planar with, or project beyond, surface Y1 but it shall not project beyone surface Y2.
