AS/NZS 4782.3:2006 PDF

Scope: This part of the Standard outlines a procedure for quantitative analysis of mercury present in fluorescent lamps that are used in general lighting service and which are covered within the scope of AS/NZS 4782.1 and AS/NZS 60901. The testing method specifies the procedures that can be used to determine accurately the mercury content in a fluorescent lamp in which mercury is introduced as the medium for discharge between the electrodes. The method involves the chemical digestion of the mercury contained within a lamp and the determination of that mercury content on a per unit basis. This is achieved using a method of solubilization of the entire mercury content contained within the tube using acidic digestion methods and the accurate determination of that mercury content using standard mercury solutions. This will allow comparisons between lamps in batches and comparisons with other internationally accepted standards for mercury content in fluorescent lamps. This Interim Standard covers methods of determination of mercury by wet chemical analysis. This Interim Standard does not apply to fluorescent lamps that are intended for special purposes as stated in Clause 1.2 of AS/NZS 4782.2.
