1. Regulation, Approval & Understanding of EN12101-3, ISO 21927-3 and SI 1001-pt7 Jamie Slowgrove Regional Manager – Asia + Flakt Woods (UK) Ltd, Colchester Factory

2. Common ground between Legislation European manufacturers are required to provide certified products to comply with EN12101-3: Smoke and heat control systems. Specification for powered smoke and heat exhaust ventilators. International Manufacturers are required to provide compliant products to ISO 21927-3: Smoke and heat control systems - Part 3: Specification for powered smoke and heat exhaust ventilators. Israel Manufacturers will be required to provide compliant products to SI 1001 Part 7: Fire Safety in Buildings: Smoke and control systems – Powered smoke and heat exhaust ventilators. EN12101-3, ISO 21927-3 and SI 1001 Pt7 are essentially based upon similar legislation requirements.

3. Background to the Legislation The Kings Cross fire (1987), and the resulting regulatory changes within the UK gave the subject of smoke control and emergency tunnel ventilation visibility, and directly drove industrial fan manufacturers product development. Further disasters in Europe, including but not limited to Mont Blanc and Tauern, have raised the profile of smoke control and emergency tunnel ventilation in Europe. European Union member states have taken action, Council Directive 89/106/EEC and Harmonised Product Standards are superseding national regulations relating to emergency smoke ventilation.

4. In 1992 the European Single Market was created. The objective was to remove barriers to trade through the European Economic Area. New Approach Directives are intended to place control on product design, with the principle objective being to provide a level playing field for product safety requirements across the European Community. The primary function of New Approach Directives is to ensure that products are sufficiently well designed and built, and that they are fit for the purpose which they are sold. The European Single Market & Directives The same principle applies to the Israel Market – the implementing of SI 1001 Part 7 will ensure all manufacturers (local or not) will operate on a level playing field.

5. The European Single Market & Directives Directives contain two distinct sets of requirements. Protection Requirements These lay down the essential health and safety requirements that must be met in order to comply with the Directive. The detail of exactly how specific products comply is left to product standards which are developed by multinational committees. Administrative Requirements, form the part of the directive that defines what manufacturers must do to enable them to demonstrate compliance with the requirements of the Directive. These are referred to as Methods of Attestation of Conformity.

6. In compliance with EN12101-3 the visible manifestation of compliance with the construction product directive is the appearance of the CE logo on the product which contains: identification number of the notified body the name or identifying mark of the producer/supplier, and the last two digits of the year in which the marking was affixed, and the appropriate number of the EC-certificate of conformity, and the number of this standard (EN 12101-3), and type of product (powered ventilator), and response delay (s), and fire resistance class Motor rating Identification & Labelling: The CE Mark It should be noted, although EN12101-3 is the basis for ISO 21927-3 standard (and therefore SI 1001-Pt7), there is no requirement in ISO or SI for CE Marking or display compliancy labels on products*. * Although existing Israel marking Tav Teken labeling will likely remain, its not required by the standard

7. The Construction Product Directive (CPD) is Council Directive 89/106/EEC of 21 st December 1988 relating to construction products. The directive lays down essential performance criteria under six general headings, including safety in case of fire. Performance requirements apply to the products as a whole, not simply to each individual components (very important for HT fans) 1. 1.Blades / Impellers 2. 2.Motor 3. 3.Casing The Construction Products Directive

8. Smoke control products are identified as having a critical role to play in the event of a fire related emergency. EN12101-3: Smoke control fans are subject to approval based on independent assessment of their performance and the on-going control of their manufacture. EN12101-3: Test houses able to perform the independent assessment are notified to the European Commission and all governments within the EU are bound to accept their test results. Conformity With the C P D There is no third party testing requirement in ISO 21927-3 standard (and therefore SI 1001-Pt7). Non-EU Manufacturers can self certify compliance to the ISO & SI standards – EU Manufactures must obtain EN12101-3 to comply.

9. The Harmonised Standard EN13501-4 The standard EN 13501-4 Fire classification of construction products and building elements – Part 4: classification using data from fire resistance tests on components of smoke control systems supports essential requirements of the construction product directive. EN 13501-4 supports the construction product directive by defining a harmonised procedure for the classification for resistance of fire of construction products. It interprets the functional requirements for the different groups of building products and explains the method for deriving their classification on the basis of test results for individual products.

10. The Harmonised Standard EN13501-4 The classifications derived for powered smoke and heat exhaust ventilators within EN 13501-4 are: F200 A constant temperature of 200C for 120 minutes. A constant temperature of 250C for 120 minutes F300 A constant temperature of 300C for 60 minutes. F400 A constant temperature of 400C for 90 or 120 minutes. F600 A constant temperature of 600C for 60 minutes F842 A constant temperature of 842C for 30 minutes. Original Israel requirements of 250C for 2 hours*, although not an official temperature classification class, would have been considered as F300 or 300C for 2 hours. *Not operating under temperature rated airflow conditions.

11. SI 1001 – Part 7 ISO 21927-3 The Harmonised Standard EN13501-4 EN 12101-3

12. The Harmonised Standard EN13501-4 Fans that are intended to be installed as part of a powered smoke and heat exhaust ventilation system, including tunnel fans, fall within the scope of the Harmonised Standard EN 12101-3. The standard was developed under Construction Product Directive Mandate M109 and compliance with the requirements of EN 12101-3 and consequent CE marking has been possible since 17 th March 2004. Compliance became mandatory within member states who have adopted the Directive on April 1 st 2005.

13. Testing, Approving & Certifying a Range

14. The standard provides a procedure for approving a range of fans. Rules allow the approved range to include scaled diameters from 0.63 to 1.26 of those tested. EN 12101-3, ISO 29127-3 & SI 1001-Part 7 Product Approval

15. EN 12101-3 Product Range Testing Requirements Tested Fans to cover full Product Range Test Approved Sizes covered by tested fans Clauses & additional requirements needed to certify the range.

16. EN 12101-3, ISO 29127-3 & SI 1001-Part 7 Product Approval EN 12101-3, ISO 29127-3 & SI 1001-Part 7 - Annex A States:

17. At least two fans must be tested at their highest rotational speed. The fan with the most highly stressed impeller must be tested. Fans powered by motors with the smallest and largest frame sizes at their highest output must be tested. The fan must be set up for test in a way that represents the conditions to which it is exposed in service. (Horizontal, Vertical, F200, F300, F400, insulated, non-insulated etc.) EN 12101-3, ISO 29127-3 & SI 1001-Part 7 Product Approval

18. Range certification may be obtained by defining a product range, and then conducting a series of type-tests that comply with the requirements for range certification. A draw back of range certification is the difficulty associated with modification of the design to accommodate a client request, or improve the product. As such range certification might be a block to product development. Single product certification may only be obtained, by manufacturing and testing an additional fan to that being sold.

19. EN 12101-3, ISO 29127-3 & SI 1001-Part 7 Product Approval Testing large tunnel fans requires a notified test house that can carry out the test. At the time of writing, only a minority of test house are able to test fans over 1.6 meters in diameter At the time of writing we believe that no notified test house is able to test the largest 4.0 meter diameter non-series produced central tunnel fans.

20. EN 12101-3: Sample Axial Fan HT Test (F400) 2 minutes, power off 2 Hour Duration

21. HT Testing Rig Examples

22. EN 12101-3 Compliance Laboratories Horizontal or Vertical installation, non- recirculating airflow. Insulated furnace

23. EN 12101-3 Compliance Laboratories Vertical installation

24. EN 12101-3 Compliance Laboratories Insulated Furnace Associated ancillary items must be tested to the same rating as the Fan

25. EN 12101-3 Compliance Laboratories Recirculating airflow, insulated, vertical mounting Furnace

26. EN 12101-3 Compliance Laboratories

29. EN 12101-3 Compliance (and subsequent ISO 21927-3 and SI 1001-Part 7 Compliance)

30. Six different and independent factors that must be adequately taken into account during a high temperature test are identified: Horizontally mounted vs. vertically mounted. Internal hot gas only vs. surrounded by hot gas. Insulated vs. non-insulated. Uni-directional vs. reversible. Auxiliary systems, direct on-line or inverter driven during fire. Form A vs. form B running. EN, ISO & SI Compliance Testing

32. Only notified bodies can perform EN12101-3 testing in order to certify fan manufacturers high temperature fans. Currently any fan manufacture can state compliance to ISO 21927-3 if they can test the product. It is possible, (although expensive) to certify large fans and or custom designed fans. e.g. Fläkt Woods has successfully EN12101-3 certified a 2.65 meter diameter fan with a 900kw motor. Fan manufacturers outside the EU who are required to comply with ISO 29127-3 and SI 1001-Part 7 will be able to self certify their product. Manufacturers inside the EU will be required to obtain 3 rd party independent certification. EN, ISO & SI Compliance Testing

33. The certificate issued by the Swedish notified laboratory SP for the Ventilator Nam Wan, a 2.64 meter diameter 900Kw fixed pitch axial fan certified at the F200 temperature / time category. Specific to one Product. EN, ISO & SI Compliance Testing

34. The certificate issued by the UK notified laboratory BSRIA for the Flakt Woods JM Aerofoil HT Range. Certificate covers F200, F300 and F400 of multiple product variations. Third Party independent Range Certification. EN, ISO & SI Compliance Testing

35. ISO 21927-3 The standard ISO 21927-3 does not contain the requirement for CE marking in accordance with the Construction Products Directive. The requirements of ISO 21927-3 are presented in: Sheard, A.G. & Jones, N.M. (2008), Approval of High- Temperature Emergency Tunnel-Ventilation Fans: The Impact of ISO 21927-3. Proceedings of the ITA–AITES World Tunnel Congress and 34th General Assembly. Agra, India, 19–25 September, pp 1817–26. In practice ISO 21927-3 is the international version of EN 12101-3 for application outside EU member states.

36. The standard SI 1001 Part 7 is ISO 21927-3, with the introduction and some key elements translated into Hebrew. The majority of SI 1001 Part 7 is the text from ISO 21927-3, to the extent that the ISO 21927-3 reference remains at the top of each page. Any product that compiles with the requirements of ISO 21927-3 also complies with the requirements of SI 1001 Part 7. SI 1001 Part 7

37. Currently there are no standards to certify HT Products for the Israel market. The existing requirement for 250/2 does not account for the fan running under load test. All European manufacturers who are EN12101-3 certified will qualify for compliance to SI 1001 Part 7 as a matter of course. All manufacturers who do not have existing EN or ISO compliance will need to either invest in their own temperature test rig or pay an existing test house to carry out the test. A reasonable timescale should be considered to allow the transition into a working standard. SI 1001 Part 7 – Implementing the Standard

38. Definite inclusion of jet / induction fans for tunnels and car parking garages. Application of EN12101-3 to very large or bespoke fans for major projects. Rules for motor interchangeability or assessing motor design changes. Rules for use with Frequency Converters by 2013. Future Amendments to EN12101-3

39. Fläkt Woods Fläkt Woods policy is to supply fans for emergency application that comply with the requirements of EN 12101-3. Fläkt Woods have EN 12101-3 certified products certified at 200C for 2 hours, 300C for 2 hours and 400C for 2 hours. Fläkt Woods have tested the highest power fan in accordance with the requirement of EN 12101-3 – a 1000 kW fan (at 400C for 2 hours), and the largest diameter fan – a 2.8 meter fan (at 300C for 2 hours). Fläkt Woods has spent ten years and in excess of £1,000,000 undertaking certification in accordance with the requirements of EN 12101-3. All Fläkt Woods products certified in accordance with the requirements of EN 12101-3 are also compliant with the requirements of ISO 21927-3 and SI 1001 Part 7.
