Hello, Has anyone tried to obtain RoHS certification for old nixie tubes or for modern homemade models?
The point of interest to me is the mercury content. RoHS allows Hg only up to 0.1% parts by weight of homogeneous material of the assembly. The exact definition is as follows: *"The term "homogeneous" means "of uniform composition throughout". Examples of "homogeneous materials" are individual types of: plastics, ceramics, glass, metals, alloys, paper, board, resins and coatings. The term “mechanically disjointed” means that the materials can, in principle, be separated by mechanical actions such as: unscrewing, cutting, crushing, grinding and abrasive processes."* Therefore, the getter pill/strip on its own is a homogeneous material that can in theory be disjointed by mechanical action... On the other hand, in document 2002L0095 — EN — 25.09.2010 — 008.001 — 1 <https://eur-lex.europa.eu/legal-content/EN/TXT/PDF/?uri=CELEX%3A02002L0095-20100925&from=EN> Page 9 - M13 4(a), states that up to 15mg of Hg is allowed - *"Mercury in other low pressure discharge lamps (per lamp)"*. This does not completely exempt nixie tubes from the mercury content but at least it is provides some limit which can be used for comparison to the XRF analysis from an RoHS certification lab. I will be eager to see if anyone else has thought about this :) -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
