ASTM E1742-05

With reference to Para 6.27.4.4, it states that the "maximum readable film density values shall be established when the viewer is procured and shall be re-establish when the viewer is repaired, moved, altered, or a different bulb, bulb designation or manufacturer is used".
Most of us are using our existing film viewers, in which the maximum film density values are checked using a light meter to measure transmitted light, in foot candles, through a 2.0D film, in accordance with ASTM E1742-00. If we do not intend to procure a new viewer, do we still have to purchase a new lightmeter to measure the light intensity in candelas/m squared, according to ASTM E1742-05? Am I right to say that it only applies to newly procured viewers?

Re: ASTM E1742-05
I believe you have to purchase a new lightmeter. The new requirement applies to the excisting viewers whenever the viewer is repaired, moved, altered, or a different bulb, bulb designation or manufacturer is used. This is my interpretation.

Re: ASTM E1742-05
Light meters currently available register up to 19,990 lux. That level will only qualify the film viewer to interprate 3.30 density film, according to ASTM E 1742-05 Fig. 2. If I am incorrect thinking this please respond.
