Test Methods, Reproducibility And Conformance To Specifications

(1) The test methods referenced for use within the applicable Standard Specification shall be used to determine the specification values for enforcement purposes. When no ASTM methods exist, accepted industry test methods specified in rule shall be used to determine compliance. (2) Premium Diesel - The following test methods shall be used to determine compliance with the applicable premium diesel parameters: (a) Lubricity - ASTM D6079; (b) Cetane Number - ASTM D613; (c) Low Temperature Operability - ASTM D4539 or ASTM D2500 (according to marketing claim); (d) Thermal Stability - ASTM D6468 (180 minutes, 150°C [302°F] ). (3) Conformance to Specifications: KEROSENE AND MOTOR FUELS QUALITY INSPECTION REGULATIONS CHAPTER 0080-05-12 (a) Conformance to Specifications - The most recent version of ASTM D3244 “Standard Practice for Utilization of Test Data to Determine Conformance with Specifications” shall be used in determining the compliance of a test value to the specification limits except that no allowance shall be made for the precision of test methods for aviation gasoline and aviation turbine fuels or other product specifications whereby the limit has been determined to be a critical specification limit. (b) AKI Limits - when determining the antiknock index (AKI) acceptance or rejection of a gasoline sample, the AKI reproducibility limits as outlined in ASTM D4814 Appendix X1 shall be acknowledged when determining conformance to the specification using ASTM D3244. (c) Tests Other Than AKI - the reproducibility limits of the ASTM or other accepted standard test method used for each test performed shall be acknowledged for determining conformance to the specification using ASTM D3244 , except as indicated in 0080-05-12-.08(2)(a) and in 0080-05-12-.02(2)(b)4.
