The referee test methods for the various contaminants are summarized in the following paragraphs. Detailed test procedures are included in Appendix C to AHRI Standard 700. If alternative
45、 test methods are employed, the user shall be able to demonstrate that they produce results at least equivalent to the specified referee test method. 5.2 Refrigerant Sampling. 5.2.1 Sampling Precautions. Special precautions should be taken to ensure that representative samples are obtained for analy
46、sis. Sampling shall be done by qualified personnel following accepted sampling and safety procedures. Refrigerants with critical temperatures near or below ambient temperature cannot be reliably sampled for both liquid and vapor phase without special handling. Note: Flammable refrigerants which are
47、ASHRAE 34 Class 2L, 2 or 3 present additional safety challenges and require additional measures for sampling safety procedures compared to nonflammable halocarbons documented in this standard. AHRI STANDARD 700-2015 3 5.2.2 Cylinder Preparation. Place a clean, empty sample cylinder with the valve op
48、en in an oven at 110C for one hour. Remove it from the oven while hot, immediately connect it to an evacuation system and evacuate it to less than 56 kPa. Close the valve and allow it to cool. Weigh the empty cylinder. 5.2.3 Vapor Phase Sampling. A vapor phase sample shall be obtained for determinin
49、g the non-condensables. The source temperature shall be measured and recorded at the time the sample is taken. 5.2.3.1 Special Handling for Low Critical Temperature Refrigerant. A vapor phase sample is required to determine non-condensables and volatile impurities, including other refrigerants. The vapor phase sample is obtained by regulating the sample container temperature to 5 K or more above the refrigerant critical temperature. 5.2.3.2 Handling for Liquid Refrigerants with Boiling Points Near or Above Ro
