Comments from members requested by 20th Feb
Comment from Alun Morgan - I have looked over the documents you sent, my opinion is that these are just non-halogenated alternatives for a number of "low tech" products. The Asian market is by far the biggest specifier of non-halogenated products, this was led initially by Sony. Of course the truth is that there is no evidence that using phosphorous based flame retardants is any more "green" than halogen based ones. However I just see this as a normal activity for Asian companies to want non-halogenated alternatives in-line with their market preference.
I do however take exception to the wording "an environmental protection class copper-clad laminate" and "play a positive role in promoting the benign development of this products" contained in the documents. Neither statement can be backed up with any evidence that non-halogenated products are either environmentally protecting nor more benign than others. I would insist on this wording being removed.

Draft standards for hologen free laminates. Members comments required in readiness for the February meeting at BSI.
Note from Dennis Price: There appears to be an abundance of low halogen laminate new standards originating in Asia but why the constant emphasis on low halogen!

Implementation of substance restriction campaigns around the world has identified the use of halogenated materials including polymers, their flame retardants and other additives as an area of concern for the EEE industry at least in part due to the following: Restriction of certain halogenated substances use (e.g. RoHS & REACH). Listing of certain halogenated substances as Persistent Organic Pollutants. Corrosivity / toxicity of combustion gas products
