The following ratings are verified by test for the Reclaimed Refrigerant Certification Program:
a.Water (ppm by weight)
b.Chloride (pass/fail)
c.Acidity (ppm by weight)
d.High boiling residue (% by volume or % by weight)
radiation
e.Particulates/solids (pass/fail)
f.Air and other non-condensables (% by volume)

n and air-conditioning products within the scope of AHRI.
1.1.1 Intent. This standard is intended for the guidance of the industry including manufacturers, reclaimers, repackagers,
distributors, installers, rvicemen, contractors and urs of fluorocarbon, hydrocarbon and carbon dioxide containing refrigerants.
1.1.2Review and Amendment. This standard is subject to review and amendment as technology advances or as additional
data becomes available. This data can be submitted to AHRI for review.
Section 2. Scope

Section 5. Sampling and Summary of Test Procedures
5.1Referee Test. 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 test methods are employed, the ur shall be able to demonstrate that they produce results at least equivalent to the specified referee test method.
5.2Refrigerant Sampling.
5.2.1Sampling Precautions. Special precautions should be taken to ensure that reprentative samples are obtained for
analysis. 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 pha without special handling.
Note: Flammable refrigerants which are ASHRAE 34 Class 2L, 2 or 3 prent additional safety challenges and require additional measures for sampling safety procedures compared to nonflammable halocarbons documented in this standard. 2
