Overview

This standard specifies sample preparation methods for determining mercury levels in new tubular fluorescent lamps (including single capped and double capped lamps, self-ballasted and cold-cathode fluorescent lamps (CCFL) for backlighting) containing 0,1 mg mercury or more. The intended resolution of the methods described in this standard is of the order of 5 %. Mercury level measurement of spent lamps is excluded from the scope, as during lamp operation, mercury gradually diffuses into the glass wall and reacts with the glass materials. The test method of this standard does not recover mercury that is diffused into or reacted with or otherwise incorporated irreversibly with the glass wall of discharge tubes. This standard does not contain information on measurement. Measurement is specified in IEC 62321. The responsible committee is DKE/UK 521.1 "Elektrische Lampen" ("Electric lamps") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
