"DB13/T 1219-2010 Method for Determination of Viscosity of Hydroxypropyl Methyl Cellulose" is a local standard in Hebei Province. It specifies the method of measuring the viscosity of hydroxypropyl methylcellulose solutions using the Uchlein Viscosity meter and the swirl/spin Viscosity meter. The standard is applicable to samples with a viscosity range of 5200,000 mPa · s in a 2% aqueous solution at 20 ° C. Low viscosity samples (5100 mPa · s) use the Uchlein Viscosity meter, and high viscosity samples (100,200,000 mPa · s) use the swirl/spin Viscosity meter. The main contents include solution preparation, equipment requirements, measurement steps and result calculation. The standard provides a scientific basis for the quality control and performance evaluation of hydroxypropyl methyl cellulose, which is widely used in chemical, pharmaceutical and other industries.
