How to show compliance for FPP and FSSP in Europe?
European route
National route

• Depending on national rules
• Fire test report (UK, IRL, )
• national approval of fire test report
• (ES, FR, PL, )
• Approval (DE)

• Approval testing AoC procedure
• ETA
• Certificate of Conformity
• Declaration of Conformity
• CE Marking

What is the difference?
European route
National route

• All regulated properties related
• to the Essential Requirements
• (CPD) to be assessed
• Durability, Serviceability
• 3rd party control
• Must be accepted throughout
• Europe

• Only resistance to fire is assessed )
• No 3rd party control )
• Accepted in other countries only
• when mutual agreement in place

) Apart from DE
6
Status of introduction of European Fire
Classification

• European classification
• Possible in all Member States
• EN Testing in many Member States obligatory for
  new tests
• Deadline for validity of national test reports
  between 2010 and 2012
• First complete obligation in AT (05/2010)

EN national in parallel
EN testing mandatory
not yet decided
tbc
7
Status of obligation - ETAs

• Product with ETA must be accepted in all
• Member States
• ETA at present voluntary in most Member States
• Only with ETA a fire test result
• must be accepted all over Europe
• ETA includes all regulatory
• requirements not only fire

ETA voluntary
ETA mandatory by law
8
Impact of legal situation for ETAs
National Level Building Regulations Only minimum
performance (fire resistance, noise protection
etc.) defined
European Level CPD From November 2006 on no
coexistence period defined for ETAGs by EC
anymore

• ETAs perceived voluntary
• No driving force for ETAs from legal side
• Only a few ETAs issued so far
• Harmonisation de facto stopped!!

9
What is the reason for reluctance of industry to
use ETAs?

• Market distortion
• because of
• Differences between European and national test
  results
• Less effort when using only fire
  test/classification report compared to a full ETA
  assessment

10
Difference EN National testing Steel protection

• Safety margins unrealistic high for reactive
  coatings
• gt not competitive
• gt Revision of EN 13381-4 and separation in 2
  parts
• Hollow sections not covered

11
Difference EN National testing Linear joint
seals

• Fire test at joint extension equal to 100
  movement capability movement not considered in
  national standards gt disadvantage when EN
  testing
• Test equipment for fire tests including movement
  not available before spring 2009

• Only 1 laboratory in Europe equipped so far
• Detailed classification e.g. EI 30 H M25 B
  W 30 to 90
• Linear joint seal with 30 minutes fire
  resistance, horizontal orientation, movement
  capability of 25, with pre-fabricated and
  on-site made splices for joint widths of 30 to 90
  mm
• Special test for curtain wall perimeter seals (EN
  1364-4)

12
Special test standard for curtain wall perimeter
joint (EN 1364-4)

• To be tested together with façade element )
• Minimum 3 m joint length
• Strict field of application rules related to use
  of standard configurations
• ETAG requires cycling before fire test (no
  equipment available in Europe so far)

) DIN standard similar to EN
13
Difference EN National testing Penetration
seals

• More severe test conditions (e.g. furnace
  pressure)
• Strict field of application rules related to use
  of standard configurations (e.g. maximum cable
  diameter of 80 mm although more severe cable
  configuration)
• Pipe end configuration as part of classification

• e.g. EI 120 U/C Penetration seal with 90 minutes
  fire resistance for closed piping systems (test
  condition capped outside the furnace)

14
Difference EN 1366-32004 and revised version 2009

• Furnace Pressure Specimen location (5.2)
  simpler approach
• Distances no obligation for 200 mm between pipes
  (6.1)
• Strut system as modern alternative for standard
  service support construction introduced, also for
  pipes (6.3.3.2, Fig. A.8 and E.10)
• Blank penetration seal necessary for definition
  of maximum seal size definition of thermocouple
  location added (Fig. 3)
• New definition of standard supporting
  constructions (7.2)
• New insulation pad for thermocouples (9.1.2.1)
  simpler to install

22
EN 1366-32009 Pipe penetration seals

• Maximum seal size to be determined by testing a
  blank seal (b or h x l), except for mortar seals
  and seals made from rigid boards or mineral wool
  boards with a density of 150 kg/m3

• Pipe end configuration U/C (capped outside!)
  covers all situations gt different to pipe end
  configuration commonly used in the past!

23
EN 1366-32009 Plastic pipes - Selection of
specimens

• Determination of Length Groups" and "Design
  Groups" (thickness and length of the active
  component of the pipe closure device is equal for
  varying device sizes / pipe diameters)
• The maximum device size per design group is
  tested in combination with maximum and minimum
  pipe wall thickness
• Design groups in the middle of the size range may
  be omitted, if the relevant parameters are
  located above the connection line (see diagram)

24
EN 1366-32009 Plastic pipes - Selection of
specimens
25
EN 1366-32009 Rules for plastic pipes Pipe
wall thickness

• The range between the wall thicknesses tested is
  covered for a particular device size
• The maximum wall thickness, tested with the
  largest device, covers all smaller sizes within a
  "Design-Group"
• Interpolation allowed for "Design-Groups" not
  tested (see diagram)

26
EN 1366-32009 Rules for plastic pipes Pipe
end configuration

• All field of application rules valid for the pipe
  end configuration tested
• Application of test results see Table.

Y covered N not covered

• Different to rules in the past!! Capped outside
  (U/C) normally used in the past! Considerable
  difference in test results!

27
EN 1366-32009 Rules for plastic pipes Pipe
material

• Similar approach like German Stellvertreterprüfun
  g but only very limited number of materials
  covered when PVC-U or PE-HD pipes are tested
• Pipe standard to be considered and recorded!
• Reaction to fire behaviour of pipes may be
  different in Germany and other Member States
  (minimum requirements in DE) gt different
  behaviour in fire test?
• More experience necessary to extend the rules gt
  common research project?

28
EN 1366-32009 New - Mixed Penetration Seals

• Combination of cables, metal pipes and plastic
  pipes or other services
• Test goal are there interactions between
  cables/cable trays and pipes?
• Standard Mixed Module

29
EN 1366-32009 Mixed Penetration Seals - Options

• Option 1 (no test results available for the
  product)
• Standard cable configuration
• Standard Mixed Module
• Pipes depending on intended field of application

cables of the Standard Mixed Module A1, B, C1,
D3, E G2
30
EN 1366-32009 The "Critical Pipe" Approach

• May save considerable test effort on pipe
  variations
• Critical pipes are
• Pipes with integrity failure within 5 minutes
  after the intended classification time
• Pipes that are closest to the 180K threshold

31
EN 1366-32009 Standard flexible wall

• Error in table of 2004 version corrected
• Smaller width possible, restrained only top and
  bottom
• New approach developed
• Varying stud widths considered
• Insulation of wall related to aperture framing
  one stop shop test situation possible to cover
  both insulated and non-insulated walls
• Number and thickness of boards only relevant when
  no aperture framing is used
• Sandwich panel constructions are not covered!
• Constructions with uncovered studs are not
  covered (e.g. shaft walls)
• Applications in rigid walls ( thickness,
  density) are covered (exception pipe closure
  devices within the wall)

32
EN 1366-32009 What to do with old test results?

• 2009 version offers more options (e.g. mixed
  penetration seals) but is more detailed and
  restrictive in standard configurations and field
  of application rules
• The difference has to be considered when test
  results from 2004 version are planned to be used
  
• e.g. only rubber cables of 2004 version may be
  considered gt tests to be repeated to get full
  cable coverage!
• Classical max/min size approach for collars/wraps
  not sufficient more tests necessary
• Tests laboratories have to make sure that a
  common approach is used throughout Europe
  training necessary also for lab staff!

33
The Future? - CPR (Construction Products
Regulation)

• First reading in Parliament passed with
  considerable number of amendments
• Discussion in Council Working Group not yet
  finished
• Current draft not consistent in itself
• Obligation for products with European Approvals
  under discussion high number of Member States in
  favour but no qualified majority so far

34
Highly safety relevant products excluded from
harmonisation?

• The bizarre situation that harmonisation for
  highly safety relevant construction products for
  applications with a special European
  classification system should be voluntary must be
  changed!!

CE Marking mandatory -
