Sample preparation for mercury content detection in discharge lamps
1 Scope
This document specifies procedures for sample preparation and testing for the determination of mercury content in discharge lamps:
This document is applicable to the detection of mercury content (not less than 0:1 mg) in discharge lamps (including fluorescent lamps and ultraviolet lamps): Other mercury-containing discharge lamps

4 Overview
Mercury in discharge lamps covered by this document is present in the following states:
a) Gaseous state in the lamp;
b) liquid metal;
c) compounds;
d) Alloys:
Due to the differences in the shape, location, composition and structure of mercury-containing devices, there are various quantitative mercury injection schemes: Although some lamps contain amalgam
Mercury is injected in the form of solid amalgam or solid amalgam, but there are also many lamps in which liquid mercury is injected:
Mercury amalgam lamps often have devices that serve as auxiliary amalgams, and the shapes and placement of these devices are very diverse:
See Appendix A for instructions on how to use the cold end method to minimize the loss of vapor mercury when opening the pipe: When the lamp is in working condition, all the mercury in the lamp tube will be rich in
Concentrated at the cold end, this will help control mercury recovery:
The procedures in Chapter 5 include methods for collecting liquid mercury, combined mercury, amalgams, and amalgams:
Liquid mercury, combined mercury, amalgam and amalgam are tested to obtain the total mercury content:
