This investigation was authorized by Mr. Paul Erdek using signed quote Q500499876. The testing began on 1/3/2014 and will be completed on 2/10/2014. A sample in good condition was provided by TSI Supercool and was received on January 2nd, 2014. The recommended dye concentration was stated to be ¼ Oz per 8 Oz of lubricant. The lubricants used for the test mixture were as follows: 1/3 4GS Mineral Oil, 1/3 CAR Quest PAG 46 and 1/3 NL POE 68. The sample was assigned the unique identification number COL1401021202-001 and tested at Intertek s facility at 1717 Arlingate Lane, Columbus, OH 43228, USA. CONCLUSION: This report concludes the evaluation of Leak Dye #22816. Based on this evaluation of Leak Dye #22816 submitted by TSI Supercool PASS the acceptance Criteria of SAE J2297 (Feb2011) Ultraviolet Leak Detection: Stability and Compatibility Criteria of Fluorescent Refrigerant Leak Detection Dyes for Mobile R-134a and R-1234yf (HFO-1234yf) Air-Conditioning Systems.

Section 7- Stability Testing: Clause 7.4.1 Neat R-134a and Lubricant Mixture TAN (mgkoh/g) 2X Recommended Dye (0.50 OZ / 8 OZ) in R134a and Lubricant Mixture TAN (mgkoh/g) Range: 3.44 5.49 Range: 4.14 4.96 Neat HFO-1234yf and Lubricant Mixture TAN (mgkoh/g) 2X Recommended Dye (0.50 OZ / 8 OZ) in HFO-1234yf and Lubricant Mixture TAN (mgkoh/g) Range: 0.58 0.94 Range: 0.38 1.19 Following the aging process for 14 days and 175 C, Using Rank Order Analysis, TAN in the sealed tubes containing double the recommended concentration of dye showed no increase in TAN compared to control samples using rank order analysis and therefore PASS the requirement. Clause 7.4.2 Following the aging process for 14 days and 175 C, for R134A, metals in the sealed tubes containing double the recommended concentration of dye did show evidence of darkening and slight copper plating but no increase was seen compared to control samples and therefore PASS the requirement. For 1234yf, metals in the sealed tubes containing double the recommended concentration of dye were untarnished, with no evidence of copper plating or corrosion. Metals in the control tubes containing neat lubricant also were untarnished with no evidence of copper plating or corrosion. Using Rank Order Analysis, test samples showed no increase in corrosion or copper plating compare to control samples and therefore PASS the requirement. Clause 7.4.3 Following the aging process for 14 days and 175 C for R134a, the liquid in the sealed tubes containing double the recommended concentration of dye was cloudy and had evidence of precipitate or insoluble material but not increase was seen compared to control samples and therefore PASS the requirement. For 1234yf, the liquid in the sealed tubes containing double the recommended concentration of dye were clear with no evidence of precipitate or insoluble material. Liquid in the control tubes containing neat lubricant were also clear with no evidence of precipitate or insoluble material. Using Rank Order Analysis, test samples showed no increase in precipitate or insoluble material compare to control samples and therefore PASS the requirement. Page 3 of 13
