The

18、liquid portion ofthe HFC Blend B must not completely fill the containersinternal volume at any temperature up to and including 130F(54C). The maximum permitted filling density for HFC BlendB shall be 58 lb/ft3(930 kg/m3). Filling density requirementsare specified in Title 49 CFR, 173.304 and Title 4

19、9 CFR,173.305.5.2.5 Handling of materials should be done in a manner thatprevents contamination or commingling of halocarbons otherthan HFC Blend B.5.2.6 Cylinders shall be free of dirt and contamination thatwould contribute to or would cause deterioration of productduring shipment or storage. Preca

20、utions should be taken toprevent the entry of oil, water, or any other foreign matter intocontainers. Unique coatings or preservatives applied prior toshipment to protect the containers are not considered contami-nation.5.3 Transportation:5.3.1 Transportation shall be as specified in accordance with

21、DOT regulations of Title 49 CFR.5.3.1.1 Shipment of materials between collectors, recyclers,and reclaimers should be within approved DOT guidelines forClass 2, Division 2.2, regulated materials. Any further provi-sions for special transportation or packaging should be agreedupon between the collecto

22、rs, recyclers, and reclaimers.5.3.1.2 The minimum design pressure requirements shall beas indicated in Title 49 CFR, Part 173.304. The pressure insidethe container at 70F (21C) shall not exceed the servicepressure for which the container is marked. The pressure insidethe container at 130F (54C) shal

23、l not exceed54 times theservice pressure for which the container is marked. Fig. 1 andFig. 2 illustrate the effect of temperature on a typical storagecylinder filled with HFC Blend B. Extinguisher filters filledwith HFC Blend B may be under additional nitrogen pressur-ization and isometric diagrams

24、for these conditions are pro-vided in Figs. 3-6.5.3.2 Transportation shall be by suitable vehicles to pre-clude cylinder damage by excessive mechanical vibration,shock, freezing, or deleterious high temperatures throughoutthe entire transport route.FIG. 1 Saturated Vapor Pressure of HFC Blend BEngli
