Scope: This standard specifies the specifications and operating instructions for glass capillary kinematic viscometers, and also specifies the calibration methods for these viscometers. This standard applies to glass capillary viscometers used in the determination of kinematic viscosity of petroleum products according to the procedures of GB/T 30515. The types of viscometers specified in this standard are modified Ostwald (Ostwald) (Ostwald) viscometer (Appendix A), suspension viscometer (Appendix B) and counterflow viscometer (Appendix C). Other glass capillary viscometers that can meet the precision requirements of GB/T 30515 kinematic viscosity determination can also be used.
