The IIR

Food quality and safety from farm to consumer Comfort in homes and commercial buildings Health products and services Low temperature technology and liquefied gas technology Energy efficiency Use of non-ozone-depleting and low global warming refrigerants in a safe manner The International Institute of Refrigeration (IIR), an independent intergovernmental science and technology based organization, promotes refrigeration knowledge and associated technologies that improve quality of life in a cost effective and environmentally sustainable manner including:

60 member countries worldwide 500 experts 600 corporate and private members

Services: F RIDOC, a refrigeration portal with over 100,000 references Journals: the International Journal of Refrigeration (IJR – the best scientific journal in its field!), IIR Newsletter, books, Informatory Notes, and Statements. Activities: Conferences Working Parties Research Projects Preparation of Standards

I NCREASING NEEDS OF REFRIGERATION I NCREASING ENERGY AND ENVIRONMENTAL CHALLENGES

8 The replacement of current HCFCs and HFCs: CO 2 Ammonia Hydrocarbons Low GWP HFCs, HFOs Others  Safety issues: Different designs Accidents possibilities without safety measures Refrigeration and Safety

9 Current regulations often not adapted technical evolutions the need to replace current HCFCs and HFCs Barriers for the current solutions Countries started to revise them (USA/ hydrocarbons, France / ammonia …) Standards discussions / class A2L These decisions will influence the global market of refrigerants  Looking at standards as well as regulations is needed Refrigeration and Safety

10 A standard is a voluntary commitment from private companies. However, they often are similar to a regulation. Many regulations are based on adopted standards Standard organizations are thus public bodies or associations at national, regional (ex.: the EU) and international levels. Participants to the definition of standards are experts, particularly from important companies. Building a standard is a long and huge work; they also must be similar all over the world.  The challenges for a country: Participating to the definition of the standards in order to represent its interest Adopting the standards already built.  Looking at standards as well as regulations is needed Standards and Regulations

11 Participating to the definition of the standards: very useful, especially for local companies however, difficult for many developing countries. Adapting and adopting international standards is necessary. It needs in any case a cooperation between governments and professionals (associations of refrigeration industries…).  Ozone officers should encourage these associations to work with them and other national bodies. Standards and Regulations

12 National systems: (More or less linked with governments)  Japanese Standards Associations (JSA)  Association Française de Normalisation (AFNOR)  Egyptian Organization for Standardization and Quality Control (EOS)  Standardization Administration of China (SAC),  American National Standards Institute (ANSI). “more than national” systems:  American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE). Regional systems:  Comité Européen de Normalisation (CEN), (+ CENELEC). National, Regional and International Systems

13 International systems:  International Standardization Organization (ISO)  (+ International Electrotechnical Commission = IEC)  for all kinds of products and systems of production (environmental management systems …).  A coordination between electricity standards and other standards (CEN – CENELEC, ISO-IEC) and between technical committees of these organizations. National, Regional and International Systems

14 A complex organization, in order to avoid overlaps. ISO: about standards and 300 committees. For refrigeration and air conditioning: TC 86 (however, others are interesting: TC 59 on Performance of household and similar electrical appliances, TC 61 of the IEC; The IEC has less members than ISO….) Within TC86, there are sub committees, particularly:  SC1 (Safety and Environmental Requirements for Refrigerating Systems and Heat Pumps).  SC8: Refrigerants and Refrigeration Lubricants. The sub committees often build one or several working groups to prepare a standard. (similar processes at other levels). National, Regional and International Systems

15 The ISO: formed in 1947 with 162 countries. At the beginning: developed countries; progressively more developing countries however, certain are still not members. Several memberships:  member body  correspondent member  subscriber member Members are national organizations. Only full members have voting rights. Costs and possibilities of influence vary according to the status chosen. National, Regional and International Systems

16 -The process (ISO): A national body proposes a new standard or a revision of a standard to the relevant committee Set up of a working group with representatives of industry and other experts  Preparation of a draft standard Revision by the technical committee and the secretariat The draft is shared with all national members who make comments New works if not enough votes for a text Publication of the standard. National, Regional and International Systems

17 Language for the work: English, but official final translations in French and Russian In some cases, the draft standard is inspired by a national standard (ex.: ASHRAE…..) In other cases, national or regional standards are built in parallel with ISO standards (CEN). In others, the adoption of a national standard follows the adoption of the international standard. However, the duration is several years. Afterwards, national regulations can refer to standards. National, Regional and International Systems

18 There are several ISO standards related to refrigeration and air conditioning. The main important ones regarding safety challenges are:  ISO 5149: on Mechanical refrigerating systems used for cooling and heating- safety requirements.  ISO 817: on Refrigerants – Designation and safety classification. ISO 5149: has recently been revised with some difficulties (previously published in 1993; revision started in 2002)= issues of charge limits for flammable refrigerants…. ISO 5149 and ISO 817: the challenges

19 ISO 817: Previously published in 2005, was revised with the delicate issue of the class A2L. The blends: more and more to classify. Constraints on natural refrigerants are also an issue in these standards as well as corresponding regional and national standards.  Evolutions on refrigerants are rapid; thus, new amendments are and will be presented in the near future regarding safety conditions. ISO 5149 and ISO 817: the challenges

20 Standards are a really important issue. Countries must adopt standards in order to avoid accidents. They must be built in connection with the industries. They must be evolutive; participating to international discussions is a way to rapidly evolve. Conclusion
