ASTM D187 standard test method for burning quality of kerosine
9. Preparation of Apparatus
9.1 Drain the lamp reservoir completely of any previous kerosine sample (Warning - Combustible. Vapor harmful), and rinse successively several times with a small portion of the kerosine sample to be tested.
9.2 Clean the lamp burner thoroughly with ASTM precipitation naphtha solvent (Warning - Extremely flammable. Harmful if inhaled: vapors may cause flash fire), removing completely any deposits from the wick-guide, air holes, and ducts.
9.3 Soak the new chimneys for 24 h in dilute HCl (Warning - Causes burns. Vapor harmful) (approximately 6 N), clean with a test tube brush, rinse thoroughly with distilled water, and dry completely. Then subject the prepared new chimneys to at least three preliminary 16-h burning periods. Clean chimneys with detergent and hot water, rinse thoroughly with distilled water, and completely dry between each preliminary burning period. New chimneys are satisfactory for use only if the last of the preliminary burning periods results in deposits essentially similar to those obtained when burning the same kerosine for 16 h with seasoned chimneys. Continue preliminary 16-h burning periods and cleanings until seasoned chimney performance is achieved.
9.4 Place several wicks into an insulated Soxhlet extraction apparatus in such a manner as to prevent distortion and extract with boiling water (Warning - Avoid skin contact with exposed hot surfaces by use of protective equipment) for 3 h from the end of the first siphoning cycle. Remove the wicks from the Soxhlet extraction apparatus, lay flat between sheets of filter paper, and press gently to remove excess moisture. Extract the wick with Formula 3A denatured ethanol (Warning - Flammable. Denatured - cannot be made nontoxic) for 3 h in an uninsulated Soxhlet extraction apparatus, drain the ethanol as completely as possible from the Soxhlet extractor and continue the extraction with ASTM precipitation naphtha (Warning - Extremely flammable. Harmful if inhaled. Vapors may cause flash fire) for 1 h.
