Maybe, if you want the matrix to eliminate the need ever to refer to a
Directive itself. 

But your list gives, IMO, a wrong impression. In practice, you have a
specific product, and you most likely have a very good idea whether the
ATEX Directive applies or not, right from the beginning of the project.
For example, if it is a food-mixer, the Directive is unlikely to apply.

So you don't have to look all through that long list, only at the item
(maybe two items) that could apply to your product.

Only to tell how complex is would be to make a practical magical matrix,
take a look below copied from the ATEX guide:

EQUIPMENT SPECIFICALLY EXCLUDED FROM DIRECTIVE 94/9/EC
These exclusions are based on Article 1.4, laid down in directive 94/9/EC:
1. medical devices intended for use in a medical environment;
2. equipment and protective systems where the explosion hazard results
exclusively from the
presence of explosive substances or unstable chemical substances;
3. equipment intended for use in domestic and non-commercial environments
where potentially
explosive atmospheres may only rarely be created, solely as a result of the
accidental leakage of
fuel gas;
4.  personal protective equipment covered by directive 89/686/EEC 39 . There
are occasions where
personal protective equipment with its own potential sources of ignition is
intended for use in
potentially explosive atmospheres. This type of personal protective
equipment should follow the
procedures laid down in directive 94/9/EC to provide the necessary level of
explosion safety (see
as well chapter 6);
5. seagoing vessels and mobile offshore units together with equipment on
board such vessels or
units, because they are already covered by the IMO Convention. However,
fixed offshore units
together with equipment on board, and units and vessels, which are not
considered to be
seagoing (i.e. below 500 tonnes, not intended for high sea but intended for
internal navigation
on river, ship canal, lakes), are in the scope of directive 94/9/EC;
6. means of transport i.e. vehicles and their trailers intended solely for
transporting passengers by
air, road, rail or water networks, as well as means of transport in so far
as such means are
designed for transporting goods by air, by public road or rail networks or
by water. Vehicles
intended for use in a potentially explosive atmosphere shall not be
excluded;
7. equipment covered by Article 296 (1)(b) of the EC Treaty, i.e. designed
and manufactured
specifically for use by the armed forces or in the maintenance of law and
order. Dual-purpose
equipment is not excluded.

Yes, is possible to make a magical matrix, but I think it would take much
much time to generate it.

No, a matrix is perhaps the best way of handling the subject

Well, it would apply.

No, the matter seems quite clear. What uncertainty do you have in mind?

Try starting with the following URL and drill downward for each directive
where you will find guidance documents and the standards listed.

Subject: Selection of Directives


Hi all,
Me again.
 
My primary focus over the last few years has been limited to ITE and 2.4GHz
SS radio products.  My contact lists and web page book marks are filled with
the necessary links to information regarding these types of products and I
am very comfortable with obtaining compliance with the required Directives
that apply.I am now exposed to many types of products destined for the
EU and want to make sure to apply the proper directives and standards.  
 
Where is the magical matrix that one can pick his directive and test suite
from for a given type of product?
 
 
 
Kind Regards,
