1.1本规程涵盖了将任何温度下的运动粘度（单位:厘斯托克斯（cSt））转换为相同温度下的赛氏通用粘度（单位:赛氏通用秒（SUS）），以及将122和210°F下的运动粘度（单位:厘斯托克斯）转换为相同温度下的赛氏Furol粘度（单位:赛氏Furol秒（SFS））。运动粘度值基于1.0038 mm的水 2. /68°F（20°C）时的s（cSt）。 注1-测量运动粘度的基本和首选方法是使用试验方法D445中概述的运动粘度计，建议以厘斯托克报告运动粘度，而不是赛波特通用秒（SUS）或赛波特糠醇秒（SFS）。 因此，保留该方法用于根据过去文献中出现的SUS和SFS数据计算运动粘度。一厘斯托克等于每秒一毫米平方（mm 2. /s） 。 1.2运动粘度的国际单位制，mm 2. /s、 在这种做法中，以华氏度为单位的温度是标准的。

1.1 This practice covers the conversion tables and equations for converting kinematic viscosity in centistokes (cSt) at any temperature to Saybolt Universal viscosity in Saybolt Universal seconds (SUS) at the same temperature and for converting kinematic viscosity in centistokes at 122 and 210°F to Saybolt Furol viscosity in Saybolt Furol seconds (SFS) at the same temperatures. Kinematic viscosity values are based on water being 1.0038 mm 2 /s (cSt) at 68°F (20°C). Note 1-A fundamental and preferred method for measuring kinematic viscosity is by use of kinematic viscometers as outlined in Test Method D445, It is recommended that kinematic viscosity be reported in centistokes, instead of Saybolt Universal Seconds (SUS) or Saybolt Furol Seconds (SFS). Thus this method is being retained for the purpose of calculation of kinematic viscosities from SUS and SFS data which appear in past literature. One centistokes equals one millimetre squared per second (mm 2 /s). 1.2 The SI unit of kinematic viscosity, mm 2 /s, and temperature in degrees Fahrenheit are the standard in this practice.
