Is Your Machinery CE Compliant?

By: 
July 08, 2009

Since 1993, the Conformite
Europeene (CE) mandatory mark has signified conformance with legal and
technical directives put forth by the European Union (EU). This CE mark has
served as an entry stamp for many industrial products and services certifying
that the producer of the product or service complies with health, safety,
and/or environmental requirements. Altogether, there are around 25 directives
requiring the CE mark certifying such areas as: safety, machinery, low-voltage
equipment, terminal equipment, and electromagnetic compatibility.

Many manufacturers understand
and comply with existing CE marking, but not all manufacturers are fully aware,
and many more are not prepared, to conform with the looming new Machinery
Directive set to become effective on December 29, 2009. Manufacturers must
understand that there are significant changes from the current directive,
Machinery Directive 89/392/EEC to the new directive, Machinery Directive
2006/42/EC.

For manufacturers planning to
compete with machinery sales into the European marketplace, it will be
essential to become well versed in the new requirements and follow up with
action plans for product compliance.

Machinery Directive: What's New

The evolving requirements
stipulated by the new Machinery Directive provide users and suppliers of
machinery with guidelines for prevention of serious injury.

Some key changes include:

Process of Risk Assessment - Machine manufacturers are obligated to complete a risk
assessment that is now defined within the directive as an iterative process of
hazard identification, risk estimation, hazard elimination or risk reduction.

Safety system requirements - Machine designers are obligated to design control
systems in such a way that a fault in the hardware or software of the control
system and/or reasonably foreseeable human error does not lead to hazardous
situations.

Harmonized standards - The standard governing the design and implementation
of the safety related parts of control systems on machinery (EN 954-1) becomes
obsolete on December 29, 2009. Machine builders must use EN ISO 13849 or EN/IEC
62061 to achieve compliance with the new directive.

Administrative and Assessment Procedures - New assessment procedures are defined for machines
listed in Annex IV of the directive and for "partly completed machines". For
manufacturers of Annex IV machines self-certification is now possible.

Machine builders outside the EU - Machine builders outside the EU must authorize a
person who must be established in the Community to compile the technical file
for the machine. Machine builders without an operation in the EU can appoint an
"Authorized Representative".

Structural changes to the new
Machinery Directive expand language to include more detailed instruction,
dictate changes in essential requirements, provide greater scope under
administrative procedures, and even review definitions of machinery.

For example, under 3.1.3 Control
Systems and Devices, the obligations on machine control system designers are
more explicitly and in some cases more stringently defined. In the main these
requirements restate with clarity that a failure of or any other cause in a
machine control system should not lead to a hazardous situation. However the
requirement to consider "foreseeable human error" is new. The design of the
safety system must be considered in a manner where machine operators do not
benefit or gain incentive from
