The Vienna Convention for the Protection of the Ozone Layer and the Montreal Protocol on Substances that Deplete the Ozone Layer logo was developed to provide a distinct brand for the two treaties across various communication assets and applications. The visual identity guideline is designed to provide a comprehensive overview of applications and correct use of the logo.
This interactive tool presents a non-exhaustive list of international, regional and national safety standards relevant to Refrigeration, Air-Conditioning and Heat Pump equipment developed by relevant Standards Organizations.
The standards are broadly classified into two categories: Main system safety standards, subdivided into Vertical system safety standards and Horizontal system safety standards, and Supplementary standards.
Categories of laboratory and analytical uses no longer exempted |
Reference |
1. Refrigeration and air-conditioning equipment used in laboratories, including refrigerated laboratory equipment such as ultra-centrifuges 2. Cleaning, reworking, repair, or rebuilding of electronic components or assemblies 3. Preservation of publications and archives 4. Sterilization of materials in a laboratory |
Decision VII/11 |
5. Testing of oil, grease and total petroleum hydrocarbons in water 6. Testing of tar in road-paving materials 7. Forensic finger-printing |
Decision XI/15 |
8. Testing of organic matter in coal |
Decision XIX/18 |

Cold-chain systems typically use high-GWP (Global Warming Potential) refrigerants and grid electricity based on fossil-fuels, off-grid diesel-based generation and transport. The urgent challenge is delivering social and economic benefits by expanding cold-chain capacity quickly and affordably, while ensuring minimal pollution and adverse environmental effects.
