Introduction (not part of the proposal)
In the Amendment 1 to Ed.3 (34A/1901/CDV voted positively), Annex E was updated to
extend the method of measuring internal elements of dual filament lamps to all such
categories, for instance the new category H19.
In the amendment of the current category sheet for H19 (Regulation No. 37), the distinct
physical shield width B is introduced (8,6 ± 0,3 mm) to ensure interchangeability of light
sources as it relates to road safety (see WP.29/2016/111; to become Resolution [R.E.5] on
the common specification of light source categories). In the category sheet for H19 reference
is made to Annex E of IEC 60809:2014 for the method of measurement of the internal
elements.

See in Figure 1 an extract from WP.29/2016/111.
Practical measurement set-ups use optical vision-systems like a projection system to
determine the dimensions of the internal elements.

Figure 1 – Category sheet for H19
Problem statement:
When using the above mentioned vision system, a measurement error is introduced due to
refraction and blurring (by the glass envelope), additional to the measurement uncertainty.
The effect is mainly dependent on the shield width in relation to the glass envelope diameter.
For lamp designs with a relatively small glass envelope diameter (there is only an upper limit
specified), the shield gets close to the glass envelope and the effect becomes significant.
Figure 2 shows a simplified drawing of the view imaging situations of the shield, with and
without the effect due to the “refractive index” of the glass envelope.
a) Physical dimension “B” when the glass envelope is removed,
b) Visual size of the shield width when measured through the glass envelope in direction ,
resulting in a “smaller value for “B”.
c) Visual size of the shield width when measured through the glass envelope in direction
“-” (the opposite direction as defined in IEC 60809:2014/AMD1:2017), even show the
contrary deviation from the real dimension, resulting in a “larger value for “B”.
