Presentation of ECC Eurovent Certita Certification is a major European certification body providing voluntary 3 rd party certification in the field of heating, ventilation, air-conditioning and refrigeration (HVAC-R) Eurovent Certita Certification certifies product performances as well as data needed to implement regulations. As an accredited certifier (accreditation n 5-0517 according to ISO 17065 by COFRAC, international recognition EA/IAF) Eurovent Certita Certification product performance certificate is recognized with a legal ground in a very large number of countries. EA : European Accreditation IAF : International Accreditation forum

Presentation of ECC Eurovent Certita Certification is: Owner of the ECP Brand: Mandated to deliver the following brands: Notified to deliver the CE marking - mandatory certification

ECC in numbers A dedicated team of 50 people based in Paris 44 certification programmes in residential domestic buildings or in industrial facilities 600 industrials certified in 44 countries in the world 1800 annual tests and 400 factory audits 2700 certificates delivered each year Eurovent Certita Certification operates with commissions responsible for the harmonization and integrity of the programs. Commissions include : Authorities, Consultants, Laboratories, Manufacturers. A Market Intelligence department that provides data on the HVAC-R market in EMEA EMEA : Europe, Middle-East and Africa 2 complementary departments among ECC : Copilot: certifies HVAC unit commissioning ProdBim: certifies Data in BIM (Building Information Modeling)

Examples of ECP programme More than 30 ECP programmes: Fan coil units Air-conditioners Filters Chilled Beams Refrigerated Display Cabinets Dry-coolers Air Handling Units Rooftops Condensers Chillers & Heat-Pumps Air to air heat exchangers Cooling towers Drift eliminators VRF

The ECP brand The Eurovent Certified Performances brand: The ECP programmes consist in independent third-party checking of product performance to encourage honest competition and to assure customers that the equipment is correctly rated on the European market. The certification relies on a continuous verification process: Analysis of the Declaration file that includes all models in the scope of the programme and selection of the units to be tested Product performance testing performed by independent and accredited laboratories On-site factory audits Check of selection software Selection software: Any kind of tool made available within the participant s organization to assist and generate an offer to customers and provide technical definition and performance of a product.

History of the IT Cooling Units programme EXISTING: ECP Close Control (CC), sub-programme of Comfort Air Conditioners (AC) Requirements, content and expectations not suitable AIM: Recast completely the sub-programme in a new dedicated programme ECP IT Cooling Units

History of the IT Cooling Units programme Key steps: February- March 2017: Call for participation to the LC 6 Launching Committees (LC): April 2017: First Launching Committee LC1 January 2018: Last Launching Committee LC6 March 2018: CPPC programme validation May 2018: Kick-off meeting Composition of the Launching Committee: 7 major European OEM of IT Cooling units 2 External independent EU laboratories 1 certification body Promotion of the ITCU programme: EU Commissions: GPP Green Public Procurement for Data Center EU ErP project commission Exhibitions: DCW

Scope of the programme The IT Cooling Units certification programme covers IT Cooling Units specifically designed and used to regulate air temperature and optionally air humidity of an enclosed space containing critical equipment such as IT equipment or telecommunication equipment. The IT cooling units shall be factory made units designed as a single packaged unit or a single split unit. Technologies covered: Computer Room Air Conditioners Direct Expansion (CRAC) air cooled or water cooled Computer Room Air Conditioner Chilled Water (CRAH) HYBRID technologies pairing these technologies Are excluded from the scope: Packaged CRAC air cooled units, Multi-Split units, Partial IT Cooling units with missing elements such as fans.

Scope of the programme Air flow directions: Down-flow Up-flow Horizontal-flow Air flow configurations: ROOM Based Cooling unit ROW Based Cooling Unit RACK Based Cooling Unit Features: Ducted/non-ducted units With/without floating-floor 50 Hz and 60 Hz frequency units

Programme Features The IT Cooling Unit certification is a stringent and exhaustive certification that includes: The Certify-all principle, which means that all the units sold by the participant on the EU market within the defined scope, shall be declared to ECC and can be subject to controls during the certification process. Annual random selection of units and tests in an independent and accredited laboratory chosen by Eurovent Certita Certifcation Between 2 and 6 tests, depending of the number of models manufactured Test realized under standard and non-standard conditions Software certification that extends the certification of the units to non-standard condition functioning points. An annual factory audit that guarantees a high level of quality of production and the relevance and accuracy between what is declared and what is produced and sold. Units tested are controlled during Factory Audit.

Thermal performances Certified performances Failure treatment: When the measured value differs from declared value Beyond Acceptance criterion: rerate of unit and BMG on the catalogue and on the software Beyond High deviation threshold: rerate and 1 additional penalty test Beyond Mean deviation threshold: a ratio that takes in consideration repeated failures along test campaigns. Leads to suspension.

Test conditions Test conditions: Each selected unit is: tested under the standard testing conditions tested under a non-standard condition Standard test conditions: Four classes of application Declaration on class 2 mandatory: For CRAH units: Class Indoor Air Entering Dry Bulb Temperature Indoor Air Entering Relative Humidity* Class 1 24 C 50% Class 2 30 C 35% Class 3 35 C 27% Class 4 40 C 20% Non-Standard test conditions: all other conditions enabled by the software

Factory Audit What is declared is what is produced by regular production: or or Finite products stock Declaration file, Technical Data Sheet, Software

Factory Audit What is offered and sold is what is declared: or or Declaration file, Technical Data Sheet, Software

Factory Audit What is produced is what is tested during the certification test: + Key control points Uniformity of the production Sampling Representativeness Test samples Whole production

Certification procedures Overview of the certification procedures: Qualification procedure Repetition procedure Declaration list: contains unit performances and technical characteristics of the components. All the OEMs models are declared in the list under the standard conditions.
