5、quisition and Use of Authentic and Conforming Refrigerant RATIONALE This document is intended to provide guidance and requirements for users during the purchase and use of refrigerants. FOREWORD To assure customer satisfaction, industry organizations must produce, and continually improve, safe, reli

6、able materiel that meet or exceed customer and regulatory authority requirements. The globalization of industry and the resulting diversity of regional/national requirements and expectations has complicated this objective. End-product organizations face the challenge of assuring the quality and inte

7、grity of materiel purchased from suppliers throughout the world and at all levels within the supply chain. Suppliers and processors face the challenge of delivering materiel to multiple customers having varying quality expectations and requirements. This document standardizes requirements, practices

8、, and methods related to: (a) refrigerant supply chain management, procurement, inspection, and tests/evaluation to assure the authenticity and conformance of refrigerant being acquired, and (b) response strategies when suspect or confirmed counterfeit refrigerant is discovered.

SCOPE 1.1 Protocols for Refrigerants Counterfeiting of refrigerants has seen a dramatic rise over the past two de

12、cades. This rise can be partially attributed to global restrictions placed on production and use of refrigerants by the 1987 Montreal and the 1997 Kyoto Protocols (1, 2). These Protocols regulate the gradual phase-out and strict regulations on the use of refrigerants with high Ozone Depletion Potent

13、ial (ODP) and high Global Warming Potential (GWP). These protocols require that older refrigerants shall be replaced with newer, more expensive, and environmentally friendly chemicals (3, 4) and necessitates redesigned or replaced equipment to operate efficiently with these new refrigerants. 1.2 Rea

14、sons for Counterfeit Refrigerants These Protocols require the staggered phase-out of these refrigerants allowing unrestricted countries a longer time to comply with the phase down. This staggered system has created an opportunity for brokers diverting high ODP and/or GWP refrigerants from unrestrict

15、ed countries to restricted countries, where they can be sold to support the needs of legacy equipment. The increasing use of air conditioning and refrigeration in developing nations has increased the demand and cost of refrigerants, which makes counterfeiting refrigerants a very economically viable

16、criminal activity. Refrigerant changes since the 1980s CFC Chlorofluorocarbons HCFC Hydrochlorofluorocarbons HFC Hydrofluorocarbons HFO Hydrofluoroolefins First, the very environmentally damaging (high ODP) Chlorofluorocarbons (CFCs) were replaced by Hydrochlorofluorocarbons (HCFCs). However, since

17、HCFCs also have ODP and GWP, they were replaced by Hydrofluorocarbons (HFCs). But that was not a perfect solution since some HFCs have significant GWP, so they are in the process of being replaced by Hydrofluoroolefins (HFOs). 1.3 Counterfeiting Refrigerant Counterfeiters primarily target non-refill

18、able/non-returnable 30 pounds/13.62 kg cylinders and 1 kg or less cans of refrigerant. Methods may include tampering with the non-refillable valves; refilling or topping-off the contents of the containers; painting or repainting and re-stenciling the exterior cylinder/can to more or less match genui

19、ne products; and/or replacing the valves. Forged trademarks and falsified outer markings, or fake company names with similar appearance to internationally known manufacturers are examples of labeling used by counterfeiters on generic cylinders/cans. Counterfeiters may also reuse genuine brand name p

20、ackaging or manufacture counterfeit packaging, and then put the forged/falsified generic cylinders/cans with unknown contents inside. 1.4 Extent of Counterfeit Refrigerants Counterfeit refrigerants are flooding markets around the world, with European and United States Armed Forces reporting signific

21、ant contamination in vehicles/equipment returning from the Middle East (12, 13, 14, and 15). The countries/areas currently most prone to counterfeit refrigerants are Indonesia, China and the Middle East, per the United Nations 2011 Report “Risk Assessment of Illegal Trade in HCFCs” (5), but they can

22、 and have been identified world-wide. The areas targeted are hot climates with high demand for refrigerants, limited inspections and/or a lack of general knowledge about the issues with counterfeits. The April 2013 United Nations Threat Assessment “Transnational Organized Crime in East Asia and the

23、Pacific” estimates that counterfeit refrigerants and illegal trafficking in high ODP refrigerants has a flow volume of 3660 tons per year totaling around US $67.7 million (11). HFOs CFCs HCFCs HFCs SAE INTERNATIONAL AS6886 Page 4 of 19 Example: In 2011, it was reported that methyl chloride (R-40) wa

24、s one of several ingredients being used in counterfeiting of various common refrigerants (6). Methyl chloride is currently not used for refrigeration because it is highly toxic (Class 2B per ASHRAE 34), corrosive and unstable - use was discontinued for the most part when the much safer and less corr

25、osive CFCs were developed (7). It is still commonly used in the production of plastics, and is very inexpensive to purchase, which makes it ideal for counterfeiting. When R-40 is blended with other refrigerants, the mix will mimic the pressure/temperature curve of R-134a, making it difficult to dete

26、ct using conventional pressure gauge tests. According to the Safety Data Sheet, R-40 is a colorless gas with a faint sweet smell (8) and is flammable. It is a suspected human carcinogen and is also a potent narcotic (9). Methyl chloride reacts with moisture in air or with water to form hydrochloric

27、acid, and explodes on contact with magnesium, and sodium. R-40 is extremely corrosive to plastics and aluminum. Furthermore, when corroding aluminum, R-40 also reacts with the aluminum to form trimethyl aluminum (a clear fluid), which is pyrophoric in air, and reacts violently with water, carbon dio

28、xide, halon, oxidizers, alcohols, carbon tetrachloride, halogens and halogenated hydrocarbons, and many other substances. (In other words, when exposed to air, the trimethyl aluminum will spontaneously combust, and then when trying to put out the fire using common fire suppressants such as water, ca

29、rbon dioxide, or halon; it can explode violently.) The first recognized incidences of R-40 being used to counterfeit R-134a involved explosions of compressor units fitted to refrigerated shipping containers (called reefers) in Vietnam and Brazil (10), which caused civilian fatalities and multiple ph

30、ysical injuries to personnel. In Southern Europe, there were multiple physical injuries (passenger poisonings when R-40 escaped the air conditioning containment), explosions, and a maintenance facility fire at a public transportation service caused by counterfeit R-134a containing R-40. R-134a is no

31、t the only refrigerant being counterfeited and many substances other than R-40 (methyl chloride) are being used as the counterfeiting refrigerants. Other common refrigerant counterfeiting schemes involve recovering refrigerants from old equipment and/or using other “filler” materials such as flammab

32、le hydrocarbons (methane, ethane, propane or butane) to increase the output of the counterfeit refrigerants. Obviously, there can be unknown/dangerous interactions from mixing multiple chemicals and contaminants. 2. REFERENCES 2.1 Applicable Documents The following publications form a part of this d
