5、 JUN2005 Stability and Compatibility Criteria for Additives and Flushing Materials Intended for Aftermarket Use in R-134a (HFC-134a) and R-1234yf (HFO-1234yf) Vehicle Air-Conditioning Systems RATIONALEThis document is being revised to reflect the requirements for R-1234yf refrigerant. 1. SCOPE This
6、SAE standard applies to any and all additives and chemical solutions intended for aftermarket use in the refrigerant circuit of vehicle air-conditioning systems with belt-driven compressors, except as noted below. This standard provides testing and acceptance criteria for determining the stability a
7、nd compatibility of additives and flushing materials (solutions) with A/C system materials and components, that may be intended for use in servicing or operation of vehicle air conditioning systems. This standard does not provide test criteria for additive, compressor lubricant, or flushing solution
8、 effectiveness; such testing is the responsibility of the additive and/or solution manufacturer/supplier. This standard does not cover additives or flushing materials for electrically driven compressors. The use of additives with electrically driven compressors might cause electrical shorting and co
9、mpressor failure. It is not the intent of this document to identify the requirements for ultraviolet leak detection dyes. Such dyes must meet the requirements of SAE J2297 for the intended refrigerant. Additives for mobile air conditioning systems are not tested under this standard for system enhanc
10、ement or performance. This standard only indicates if the additive is chemically compatible with materials used in the system components. Flushing solvents, when used, completely fill the component/system being flushed and, hence, should not harm system components at 100% concentration. They are not
11、 intended to remain in the system, either as a solvent or as an additive, but, because it is not possible to remove all of the flushing solvent, an indeterminate amount remains. The residual remaining in the system depends on many factors, including system/component configuration, component blind sp
12、ots where liquid cannot be removed, the volatility of the solvent, the procedure(s) used to remove the solvent, and evacuation capability and procedure. No means exists to identify and/or specify the amount of residual solvent that either can, or will, remain in any given system after the procedure(
13、s) have been followed. This standard does not address the flushing solvent procedure or its effectiveness at removing residual flushing agent. 1.1 The purpose of this standard is to provide testing and acceptance criteria to evaluate the stability and compatibility of chemicals, including flushing m
14、aterials and additives (e.g., to enhance lubrication, durability, cooling performance, energy performance, prevent/fix leaks) intended for use in either R-134a or R-1234yf vehicle air conditioning systems using belt-driven compressors. Successful completion of all requirements contained in this spec
15、ification indicates acceptable compatibility with the AC system materials, but does not suggest that the additive improves system performance in any way. R-134a systems and R-1234yf systems are different systems. Additives must be identified as applicable to the specific refrigerant and pass the req
16、uirements of this specification for that particular refrigerant before referencing SAE J2670 on the product container. SAE J2670 Revised FEB2011 Page 2 of 82.

SPECIFICATIONS AND GENERAL DESCRIPTION 3.1 The additive or flushing solution shall be certified that it meets this specification by a qualified, ISO certified laboratory. The laboratory shall maintain documenta
21、tion of testing to this specification for each change in formulation certified, including all calibration data and equipment calibration dates for a period of 5 years following the end of the production run for a certified additive. 3.1.1 Certification of compliance with this Standard can be verifie
