Prior
to the implementation of such Directives many or all EU member states
will have had their own regime for regulating the products in question.
Each regime was based upon a national perception of related safety
hazards and was evolved in isolation from the other nations. This
effectively created a barrier to trade – a product acceptable to
some EU member states was not acceptable to another.
The EU Product Directives are intended to create a single legal
structure within which products can be sold on the EU market without
having to submit to a multitude of national assessment and approval
regimes in member states.
A product that is proven to comply with the appropriate Directives
in one EU member state must be accepted in all member states.
A product must display the now-familiar CE marking (shown above)
once this has been achieved.
As these Directives are intended to overcome trade barriers, a Directive
has achieved its purpose once a product has been traded. Thus products
falling within the scope of such a Directive must comply at the
first point of being "put on the market" or being "put
into service". Thereafter the Directive carries no bearing
on the operation and maintenance of the product. Other types of
European Health & Safety legislation or national regulations
may, depending on the product, regulate these issues downstream
of the point of sale.
New
& Global Approach Directives
Current European Product Directives are written by the Commission
incorporating two "templates" known as the New Approach
and the Global Approach. These lay down the way that standards
must/may be used to support the requirements of the Directive, the
methods used to assess conformity and where thrid-party certification
is required.
New Approach – Harmonised Standards
Traditional legislation (the "Old Approach"?)
tended to include precise technical details& equations within
the text of the legislative document. While this made assessment
against the legislation easy, it has one big drawback: unforeseen
developments. A new material or novel product, that was not foreseen
at the time of writing the legislation, might not fit the technical
requirements. If it could not comply it would be illegal, even if
perfectly safe. In order to legalise the new product, the legislation
would need to be updated.
The Commission’s current workload of new legislation is such that
amending existing Directives is low priority and can take a decade.
During this time there would be a danger of non-EU competitors stealing
a lead in technological development.
To avoid this situation, the New Approach Directives now only list
Essential Safety Requirements in general terms. The precise
technical details of conformity are left to the manufacturer to
justify. The manufacturer is not without help. For each New Approach
Directive, CEN, the European Standards Organisation, is mandated
to draw-up a new range of standards to provide supporting technical
detail. On completion, these standards must be adopted by each Member
State and any conflicting National Standards of their own must be
removed. In so doing, the standards become harmonised across
the EU.
These harmonised standards provide the manufacturer with
one solution for consideration. They are the easiest solution as,
in becoming harmonised, they have already been agreed as meeting
the requirements of the Directive. The harmonised standards, therefore,
carry a presumption of conformity: an authority may question whether
the standard has been properly applied; they cannot question the
suitability of the standard itself.
A manufacturer is not obliged to apply a harmonised standard. If
a solution, alternative to harmonised standards is used, the manufacturer
must demonstrate equivalent safety. This is difficult to do and
can always be questioned by an authority. One effective solution
to this problem is provided by CEproof’s HAZproofTM
service (Contact us).
Global Approach
The global approach lays down standard routes
for conformity assessment. Each "route" is called a module.
There are 8 standard modules (see below) but these can be slightly
altered in some Directives. The European
Pressure Equipment Directive (PED) is a significant example
where there are many alterations to the modules. Other Directives
such as Machinery and Simple Pressure Vessels do not properly explicitly
define modules although their prescribed conformity assessment procedures
align closely to them.
Module Description
| A |
Internal Production Control |
| B |
EC Type Examination |
| C |
Conformity to Type |
| D |
Production Quality Assurance |
| E |
Quality Assurance for Final Testing |
| F |
Product Verification |
| G |
Unit Verification |
| H |
Full Quality Assurance |
Modules A, G & H are applied individually and module B is applied
in conjunction with one of modules C, D, E or F.
A third party, known as a Notified Body, must verify conformity when
a manufacturer applies all modules except A and C. It is clear then,
that these modules are only permitted for "low risk" products.
Higher risk products are required to submit to outside verification
of design (B) and/or quality audits (D, E & H) or inspection of
samples of production (F) or inspection of every unit of production
(G). Each Directive has its own system for categorising risk
and assigning modules. Further details of certain Directives
are given on this website but CEproof is able to help on a very
wide range of European Directives. Please contact
