31、d to the fact that a refrigerant other than R-134a would require special handling by someone with specific expertise and equipment. 6. FUNCTION DESCRIPTION 6.1 The equipment must be capable of continuous operation in ambient temperatures of 10 C (50 F) to 49 C (120 F). Continuous is defined as compl
32、eting recovery operation with no more than a brief reset between servicing vehicles, and shall not include time delays for allowing a system to outgas (which shall be part of the recovery period provided by this standard). 6.1.1 The equipment shall demonstrate ability to recovery a minimum of 95.0%
33、of the refrigerant from the test vehicle in 30.0 minutes or less, without prior engine operation (for previous eight hours minimum), external heating or use of any device (such as shields, reflectors, special lights, etc.), which could heat components of the system. The recovery procedure shall be b
34、ased on a test at 21 to 24 C (70 to 75 F) ambient temperature. The test system for qualifying shall be a 1.4 kg (3.0 lbs) capacity orifice tube/accumulator system in a 2005-09 Chevrolet Suburban with front and rear A/C or the test option described in Section 9. It is recommended that, prior to use,
35、recovered refrigerant be checked for the presence of other refrigerants by using a refrigerant identifier certified to meet SAE J2912 or J1771. 6.1.2 The equipment shall demonstrate ability to recover a minimum of 85% of the refrigerant from the test vehicle or system of 6.1.1. in 30.0 minutes or le
36、ss, at an ambient temperature of 10 to 13 C (50 to 55 F), subject to the same restrictions regarding engine operation and external heating. 6.1.3 During recovery operation, the equipment shall provide overfill protection so that the liquid fill of the storage container does not exceed 8RIWKHWDQNVUDW
37、HGYROXPHDW C (70 F).
