Appearance: Transparent, free from suspended particles, mechanical impurities, and undissolved water. Visual inspection. 1) 1/can. Flash point (closed cup), °C ≥ 33. GB/T2611. 1/can. Colority, number ≥ 25. GB/T3555. 1/can. Aromatic content, % ≤ 15. 2) SH/T0118. 1/can. Rosin butanol value. Reported as per GB/T11134. 1/can. Bromine value, gBr/100g ≤ 5. GB/T11135. 1/can. Driscoll test: Pass. SH/T0174. 1/can. Boiling range: Initial boiling point, °C ≥ 140. GB/T6536. 1/can. Temperature at which 98% of the liquid evaporates, °C ≥ 200. Copper sheet corrosion (100°C, 3 hours), grade ≤ 1. GB/T5096. 1/can. (50°C, 3 hours), grade ≤ -1. Density (20°C), kg/m3: 750–816, ≥ 790. GB/T1884. 1/can. Note: 1) Pour the oil sample into a 100 ml glass measuring cylinder and observe it at 20±5°C; the sample must be transparent, free from suspended particles, mechanical impurities, and undissolved water. 2) This indicator allows the manufacturer and the user to negotiate based on the user’s needs. 10
