checking filament dimensions and position.

CATEGORIES HB4 AND HB4A

Sheet HB4/4

Screen projection requirements
 This test is used to determine, by checking whether the filament is correctly positioned relative to the reference axis and the reference plane, whether a filament lamp complies with the requirements.

d = diameter of filament
The filament position is checked solely in directions A and B as shown on sheet HB4/1.
The beginning of the filament as defined on sheet HB4/3, note 12/ shall be in volume "B" and the end of the filament in volume "C".
The filament shall lie entirely within the limits shown. Volume "A" does not involve any filament centre requirement.
