  1. IECEx Industry SymposiumShanghaiIECEx and EuropeIntegrating IECEx and ATEX Ron SinclairManaging Director – Baseefa

  2. Two ATEX Directives • 94/9/EC – concerned with trade of manufactured equipment intended for installation in hazardous areas“The ATEX Product Directive” • 1999/92/EC – concerned with safety of workers and the public in respect of installations in hazardous areas“The ATEX User Directive”

  3. ATEX Directive 94/9/EC • Council Directive 94/9/EC of 23 March 1994 on the approximation of the laws of the Member States concerning Equipment and Protective Systems intended for use in Potentially Explosive Atmospheres • ATEX = “Atmosphere Explosible” = Potentially Explosive Atmosphere

  4. ATEX Directive 94/9/EC • Applicable throughout European Economic Area (EEA) = EU (25)+ EFTA (3) (+Switzerland) = 29 • Voluntary application since 1996 • Compulsory application since 2003 • It is a “Trading Directive” • Concerns safety only to set minimum levels to prevent concerns on safety being a barrier to trade

  5. ATEX Directive 94/9/EC • Broad Scope • Equipment (Motors, Luminaires, Diesel Engines, Pumps, Fans, Conveyor Belts Instrumentation, etc.) • Protective Systems (Flame Arresters, Suppression Systems, Venting, etc.) • Safety Related Devices (IS Safety Barriers, Motor Protection Relays, etc.)

  6. ATEX Directive 94/9/EC • Defines Categories of Equipment based on risk of becoming an active ignition source • Definitions for mining and surface industries differ slightly • IEC TC31 has adopted the principle and has started to allocate “Equipment Protection Levels” (EPLs) with similar definitions

  7. ATEX Directive 94/9/EC • Category 1 • Very high level of protection • Ex ia, Ex ma, techniques in 60079-26 • Category 2 • High level of protection • Ex d, Ex ib, Ex mb, Ex e, etc. • Category 3 • Normal level of protection • Ex n, Ex ic

  8. ATEX Directive 94/9/EC • Category M1 • Intended to remain energised when an outbreak of gas has been detected • Ex ia, Ex ma • Category M2 • Intended to be de-energised when an outbreak of gas has been detected • Ex d, Ex ib, Ex mb, Ex e, etc.

  9. 94/9/EC plus 1999/92/EC • The two ATEX Directives work together to create safe installations • Allocate Categories of Equipment for use in Zones (unless a specific risk assessment allows different) • Category 1 – Zone 0, Zone 1 or Zone 2 • Category 2 – Zone 1 or Zone 2 • Category 3 – Zone 2

  10. ATEX Directive 94/9/EC • Compliance against “The Essential Health and Safety Requirements” (EHSRs) from Annex II • Standards have a subsidiary role supporting claims of compliance • Harmonised standards are deemed to demonstrate compliance • Use of other standards has to be justified

  11. Harmonised Standards • IEC 60079 series (and other IEC standards) are being adopted as EN 60079 series, etc. • These replace older Cenelec Standards in EN 50014 series • Europe is committed to adoption of IEC standards in Ex Field by “parallel voting”

  12. Harmonised Standards • For list of current harmonised standards see http://ec.europa.eu/enterprise/atex/stand.htm • For information on how to deal with changing harmonisation status seehttp://www.baseefa.com/page58.asp

  13. ATEX Directive 94/9/EC • Compliance against EHSRs to be reviewed against “State of the Art” of technological development • Harmonised standards are presumed to show “State of the Art” • Other standards may be even more valid but justification for use must be provided

  14. ATEX – Is it Certification ? • ATEX is a mandatory legal device • Only partly certification • Process depends on Category • The key document, “The Declaration of Conformity” (DoC) is always issued by the manufacturer without any monitoring by a third party • The DoC may, or may not, be reliant on evidence from a third party

  15. IECEx vs ATEX • IECEx is a true Type 5 Certification Scheme for all equipment, giving the identical level of confidence for everything • ATEX only approaches Type 5 level for Category 1 (and M1) Equipment and Protective Systems, giving progressively lower confidence for the lower Categories

  16. IECEx vs ATEX • IECEx • ExTR + QAR >> Certificate of Conformity (issued by IECEx Certification Body and searchable on IECEx web site) • ATEX Category 1 (or Cat. 2 electrical) • EC-Type Examination Certificate + Quality Assurance Notification (or ??) >> Declaration of Conformity (issued by manufacturer on own responsibility)

  17. IECEx vs ATEX • IECEx • ExTR + QAR >> Certificate of Conformity (issued by IECEx Certification Body and searchable on IECEx web site) • ATEX Cat. 2 non-elec. + Cat 3 • Manufacturer constructed Technical File >> Declaration of Conformity (issued by manufacturer on own responsibility)

  18. ATEX Advantages • Flexibility • need not stick to exact wording of standards if alternative justification against EHSRs is contained in Technical File • BUT • Not transparent as the only publicly available document is the Declaration of Conformity • Technical file invisible to purchaser

  19. IECEx Advantages • Transparency >> Confidence • Conformity is exactly against requirements in declared IEC Standards and Certificates are available on web site • BUT • Cannot use useful developments in draft standards until finally published and included in ExCB scope

  20. ATEX Advantages • Notified Bodies are readily appointed by Member States • Plenty of choice for manufacturers • BUT • Some bodies have limited expertise and basis for notification is not clear • Some bodies treat essentials (such as provision of a report) as a chargeable extra

  21. IECEx Advantages • Appointment of ExCBs and ExTLs is by a system of peer assessment • Transparent and leads to mutual confidence • Reporting is obligatory and subject to random peer review • Leads to customer confidence in the scheme and therefore value of certificates • BUT • Prevents those that may be so inclined from cutting corners

  22. The Route for Europe • Target End Point • IECEx Certificates of Conformity fully accepted without further paperwork • Problem • IECEx is about Safety • ATEX is about Trade • European Commission would need to change the whole structure of its approach to trading directives !

  23. The Route for Europe • Interim Solution 1 • IECEx Documentation accepted with an ATEX “Cover Sheet” • All the technical work is done once within the IECEx framework • Possible currently for all 60079 series standards plus some others

  24. Interim Solution 1 • Works best when single body does all the work • ATEX QAN based on IECEx QAR • EC-Type Examination Certificate based on ExTR • N.B. Purpose of IECEx CoC and EC-Type Examination Certificate are different

  25. Interim Solution 2 • Involving two certification bodies • One outside Europe • One inside Europe • Need for additional report to show how the ExTR is accepted for ATEX • Need for QAN based on QAR • Issues of accreditation, notification and public liability insurance for the European Body

  26. Interim Solution 2 • The ATEX Notified Body has to take full legal responsibility and show the necessary paperwork • The Notified Body is responsible to the European Commission via its national government

  27. The Paper Trail • All certification activities require a paper trail • The IECEx Scheme paper trail is prescribed to a major extent within the scheme • The ATEX Directive does not prescribe particular forms of paperwork

  28. The Paper Trail • The IECEx paper trail is satisfactory for ATEX • Most forms of paper trail devised for ATEX would not be acceptable for IECEx • It is not unknown for a European Notified Body to refuse to release the report to its customer !

  29. The Baseefa PhilosophyProduction Control • All work being done for ATEX QANs is being reported in a format acceptable for an IECEx QAR • The customer gets exactly two for the price of one • We do no extra work, so there is no extra charge

  30. The Baseefa PhilosophyDesign Test and Assessment • If our customers are able to use standards acceptable to IECEx, there is no extra charge for the technical work • There are additional sheets of paper to cover ATEX and IECEx, but the cost is minimal for most projects

  31. IECEx plus ATEXThe Benefits • For very little extra cost • Future proofed acceptability throughout the world as the IECEx Scheme grows • Legal acceptability in Europe
