Background to CE Marking
Implications for Fabricators
What products does it cover?
How do I implement it?
What about specifiers?
What about galvanizing?
1. Background to CE Marking
Objective:
To promote
common standards
across Europe in
order to
make trade easier.
Phased introduction started 1988
21 directives requiring CE marking
3 directives not requiring it.
Requirements vary between directives
To ensure items being sold are:
well designed, and safe.
Toys and electronics are well known
To be CE marked
Construction Products Directive
•Removing technical barriers to trade
•Replacing national standards
with harmonised EU standards.
Being replaced with the
Construction Products Regulations
7 Main requirements…
•
•
•
•
•
•
•
Mechanical resistance and stability
Safety in case of fire
Hygiene, health and environment
Safety in use
Protection against noise
Energy economy and heat
retention
Sustainable use of natural
resources
2. Implications for Fabricator
•Who is affected?
•What does it mean?
•What do I do?
•What deadline?
•Consequences of not doing it?
BS EN 1090
:Execution of steel and
aluminium structures
Part 1
:Requirements for conformity in
assessment of structural components
Part 2
:Technical requirements for
steel structures
When?
CE marking is mandatory from July 2014.
Non-compliance is a criminal offence
Consequences?
Non-compliance is a criminal offence
“Policed” by Trading Standards.
3. What products does it cover?
Covers all fabricated steelwork from purlins to
portals, from bridges to frames. All steel into the “built environment”.
Covers components made from:
Hot rolled steel, Cold-formed steel, Flat products (plates, sheet and
strip), Bars, castings and forgings.
Applies to:
•Series production (purlins, sheets, decking etc)
•Bespoke structures
•Components made from kits of parts
What products does CE Marking apply to?
Construction Products – “any product or kit which is produced and
placed on the market for incorporation in a permanent manner in
construction works or parts thereof and the performance of which
has an effect on the performance of the construction works with
respect to the basic requirements for construction works.”
Article 2 definition 1 of regulation No EU-305/2011
Construction Works – “any buildings and civil engineering works.”
Article 2 definition 3 of regulation No EU-305/2011
What does that practically mean?
•Steel frame (columns, rafters, bracers etc)
•Lintols, beams, frames, ties
•Stairs, handrails, fire escapes, doors
•Culverts, bridges, walkways
•Water works access systems
•Roads and highways systems
4 How do I implement it?
Constructor responsibility
Manufacturer’s declaration of conformity
Warranty that product meets the specification
Safety critical products
Must have suitable Factory Production
Control (FPC)
FPC needs to be certified by a Notified Body
Linked to Execution Classes
Welding is a special process
Reliance on the “system” and the “personnel”
Competent welders and inspectors required
Competent welding coordinator
How do I implement this?

4.
Know the requirements of the standards applicable to your
products.
Use the specified test methods to ensure conformity with
those requirements.
Implement a system for controlling regular production.
Mark the products in the specified way using a suitable
classification and designation system.
Factory Production Control.
ISO 9001 is a form of control, and probably
Covers most of what is required.
Do you have traceability of materials?
Of processes? Of qualifications of welders?
Notified Body
Similar to the body who audits your ISO9001 quality system.
Independent, authorised by EU, audits your systems.
Execution Class
One level of control is not suitable for every application.
The degree of control in welding components for nuclear
Industry is not the same as for a fence!
Execution classes divide these levels of consequences
of failure into several categories.
There are four execution classes
Determined in a similar way to risk
assessment.
1.
2.
3.
4.
Simple structure, low consequence
Medium structure, moderate consequence
More complex, higher risk
Most complex, highest risk.
Examples
1.
2.
3.
4.
Small fire escape, gates, handrail
Farm Building structure
Office Building, factory
Nuclear Power, Oil & Gas.
Execution Class determined by these factors:
•Consequence Class
•Service category
•Production Category
Setting the execution class is the designer’s
responsibility
Welding Coordinator
Welding is a critical process.
Coordination of materials, processes, people
Qualifications? Standards? Documented
Processes?
Implementation example…
Structural steel fabricator
Planning to fabricate for a factory building
Has the contract in hand, and is planning the execution.
Steel grade:
Standard:
Designed
S235
EN10025-2,3,4,5; EN10149 - 2, 3;
Engineer
5. What about Specifiers?
The specifier or designer of steel products covered by
the regulations must state the standard to be worked to
and the execution class.
Some designers are unaware of their responsibility in
this respect.
Consequence Class:
Service Category:
Production Category:
= Execution Class

6. What about galvanizing?
What happened?
Galvanizing can have an impact on structural integrity.
Part of a process not under the control of the fabricator
Fabricator needs some assurance that integrity has not
been compromised.
Prior communication is key!
Discuss the plan of action with the galvanizer.
Swap drawings where appropriate
Changing a drawing is a low cost activity compared
to changing steelwork between fabrication and
galvanizing.
Galvanizers Association with British Constructional
Steelwork Association have developed a course for
post galvanizing inspection.
Qualified inspectors
Good information
Test certs,
material descriptions,
drawings
Typical Info to consider for galvanized
steel.
•Steel composition
•Identification of significant surfaces
•Flame, laser or plasma cut surfaces
•Vent and drainage holes adequate
•Coating thickness requirements
•Passivation or painting requirements after galv.
What should you expect from the
galvanizer?
•Qualified inspector available.
•Inspection of the material pre and post galvanizing.
•Zinc melt must conform to ISO1461, and be proven to
conform.
•A Quality Management System conforming to
ISO9001:2008
•A system of material traceability.
•A record keeping system that preserves info for TEN
years.
Cold Comfort….
Other industries have the same problem.
Insulation products: August 2012
Aggregates (rock!)
Toys (covered in 1988)
Mastic and adhesives
Glass
Sewer pipes
Toilets
