§ 654. Out-of-Focus Tests.

Tests of nonsealed or semisealed units for driving and passing lamps shall be made in each of four out-of-focus filament positions. Where conventional bulbs with two-pin bayonet bases are used, photometric tests shall be made with the light source 1.52 mm (0.060 in.) above, below, ahead, and behind the design position. If prefocused or halogen H1, H2, H3, or H4 bulbs are used, the limiting positions at which tests are made shall be 0.51 mm (0.020 in.) above, below, ahead and behind the design position. The lamp may be reaimed for each out-of-focus position of the light source. The minimum requirements for the out-of-design positions shall be 80% of those specified for the design position; the maximum requirements shall be the same as for the design position.
